Mac Pro :: Usb Not Working / Just Fans And Hd Spinning
Jul 12, 2009
Ok, so I got a Mac Pro I believe it's a 2007 model or some where along those lines, it's 2.63 ghz quad core.None the less here is what happened.Came home one day to find my USB not working at all it would charge but not connect to the computer.
So I reboot still not working. I turn it off and take a look inside nothing, reseat the ram just to be sure. Ok, turn it on, nothing happens, no screen I hear the fans spinning and the hd spinning.So I take out each card and try one by one to see if any one them are causing a problem nope.As a side note the computer light comes on, but if I like the power button it just shuts right off. Also the computer power up when I put the plug in the back without pressing the on button.
today i took the computer apart to see if I could find any blown caps... hmm nope. Went to the local computer store but they don't test for anything mac so he said I could try out their power tester nothing would light up on the tester but it may have been wrong pins. CD drive showed all voltages but 3.3v.Now im not sure if it's the MOBO or the Power supply is there any way to test this out? or if I toast something else? I have no clue.

I opened up my G5, to install more RAM, and saw that one of the hard drives was unplugged (I just got it used), and so I connected that, blew some compressed air into it, installed the RAM and closed 'er up. Then I tried to power on and it didn't work (No Chimes, just fans spinning, no video, not even the start up chime). So, I disconnected the hard drive, took out the RAM I put in, and closed it, and it still doesn't boot. Same thing. My keyboard is wireless, but the wireless dongle thing doesn't get any power when it is "powered on". The fans are spinning all the time. (Except when it's powered off, obviously)

For the last couple of days my fans have been going crazy, spinning at 6200RPM non stop. I installed fan control last month but the issues just started. When I open up fan control it says my fan should be spinning at 4000RPM. I had smcFanControl installed before and its still installed. My bluetooth module over heated yesterday so I used SMC to rev up the fans. I don't know if that is the issue because it isn't running now. I'll try uninstalling that now.

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.

Exactly the same issue on Macbook Air and new iMac both running Safari 5.1 and Lion 10.7.3Â
When I open Safari it does not open a page, it just shows a spinning beach ball and shortly after the fans kick in and the activity monitor shows 1 webprocess at 99 - 100% or sometimes 2 web processes at 50/50% all coming from the User. When I inspect the process it says it's "Parent Process (Safari 450)"Â
When I quit safari the web processes stay at 100% and will only stop when I quit them in activity monitor. I have reset Safari but no joy. Firefox etc works fine. The only update I ran was a 1Password update but they say it's not them.Â

My parents have an older 20-inch white Intel iMac that has run great through the years. But about a week ago it just started spinning the CPU fans up to 3500-4000 RPMs and it won't bring them back down. Istat shows that the CPU temp is around 90 degrees and the computer remains cool to the touch.
So it isn't overheating. My parents keep it off most of the time because they don't want to ruin it, but they're planning on using it in their business they're trying to start up. We've done some web searches and nothing seems to fix it.

My father owns one of the original G5s, so its power pc not intel. Today while browsing an excel spreadsheet he says part of the screen turned black, then the monitor shut off, then the monitor came back on but not video. Mean while the fans started spinning out of control. Now when he tries to turn it on, he gets power, but all that happens is the fans spinning faster and faster and faster until he turns it off. No video or anything. Just speeding fans. He fears the CPUs died since they control the fans. Any suggestions? He also says the fans were spinning unusually fast these last few days.

I was wondering if anyone has had this problem or would be able to help me out.I've installed Windows 7 on my 2006 mac pro (mac pro is still in Leopard 10.5 and have'nt used any bootcamp drivers). Everything installed fine and seems to work ok but after about 30mins or so all the fans appear to shut down which can't be a good thing. Should I've installed it with Snow Leopard?

I am using a MacBook Pro 15inch (bought last April) Recently I have noticed that after short periods of time of using it, the laptop seem to get very very hot, a lot more than usual. I have also noticed that the fans get quite loud when it is doing some heavy processing, but a lot more than normal..My main concern is hot it gets, is there some way to check if my fans are working properly.

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

When I have documents open and I walk away for a few minutes, when I come back and resume working, my computer freezes up and the little pinwheel starts spinning. I literally have to unplug it to get out of this frozen state. This has been getting progressively worse over the past three months. They told me to add more memory, which I did. However, the problem persists. Do you know why my computer would freeze up after the screen has had no activity for just a few minutes? My screen saver is set for an hour so I know this is not the problem.
Info:
iMac, Mac OS X (10.4.11)

I don't know what my wife did to her 13" white MacBook, but Firefox is slow as molasses. Safari is working perfectly, but all of her bookmarks are in Firefox. I made sure she was on the correct network, than added opendns settings to DNS. I downloaded and installed the most recent Firefox and repaired permissions on the drive. I rebooted - same problem. Random beachballs causing the app to be useless. Safari works perfectly, so it's not an Internet issue. I haven't tried other apps to be sure but right now it seems confined to Firefox.

I just acquired a G4 MDD Power Mac. Dual 1 Ghz processors.I pulled the HD out of my older g4, connected it, and powered the machine up. The HD has OSX 10.5 and works fine in the older G4.
The first thing I notice is that the Small fan (in the door) is spinning, but the Large fan under the Power Supply is NOT. The red light on the Motherboard is on.
What happens is that all I get is a white screen, with the Apple Logo, and the spinning circle. it never acceses the hard drive and boots into 10.5 What does this point to? I hope the Dual processors are not the problem here. But that large fan not spinning worries me.

When I wake from sleep, my mouse cursor is a beachball that is NOT spinning. I can use my mouse like normal, move it, and click on things, but its still a beachball. I beleive it stays like this until the mouse is actually supposed to be a beachball (when I open a few programs at the same time and the computer starts "thinking"), then it starts spinning and after that it goes back to the normal black arror cursor.
Might be a problem from the 10.5.3 update? anyone else experience this?

So lately I've noticed my Macbook Pro to be quite noisy. According to iStat menus, the fans seems to always be running at 4,000 RPM, even if I am just staring at my desktop, with nothing open.
They speed up normally when the CPU is under load, but they never go lower than 4k.
I tried using SMCFancontrol to restore the default settings, but they still run fast. I even reset the SMC the other day hoping that would fix it, but it didn't.
I've checked activity monitor and used a few terminal commands to check for any processes that are causing high cpu load or anything weird, but I haven't found anything.

Does anyone now if there are available power ports on Mac pro 1,1 logic board for some additional fans, without running cables down from the optical drives.

My OWC RAM is working just fine, but I am growing increasingly concerned about the temperatures at which it runs. I have the 3.0 (120W) MacBook 2008 with 18 Gb RAM (4x4Gb + 2x1Gb apple stock). The RAM in memory module A2 & B2 is getting up to 80 Celsius without even much of a workout on the RAM. What's more, the MacPro fans are not increasing - right now the hottest module is at 76 Celsius and fans haven't increased at all (see screenshot below).
I have installed SMC fan control, which I understand is supposed to set the minimum fan speed, which I have set at 730 because my RAM was running hot even without any workout. How concerned should I be about this? Is this a) a defect in my mac pro b) a design flaw c) a problem with OWC memory, or d) is everything OK and I'm making a mountain out of a molehill?

I saw a single post somewhere on these boards about something called "coolbook" which is a utility that undervoltages (is that even a word?) the chip to make it run cooler.
It's $10 to give it a try. Wonder if anyone with fan issues would give this a try to see if it changes the heat/fans much?
Google coolbook and you will find it.

I've been advised to clean my MBP fan's out with compressed air, since I've owned it for 6 months now. So my question is, where would I actually spray the compressed air without opening the chassis? I'm scared to use it on the keyboard because I've heard keys popping off that way, and wondering if I spray into the vent below the screen, I would just blow the dust deeper into the computer...

My Unibody 17" MacBook Pro (10.5.8) Is having a few issues that I cant figure out how to deal with.
I got this laptop I think in April. And a few weeks ago I noticed the a loud humming noise that wasnt there before. It seems, after finially looking into this problem, that my fans are running at full speed from the second I hit the power button, right until the machine shuts off. I installed istat and it says the fans are running at about 5700 rpm. I guess the good news is that It doesnt ever get warm. Although this fan noise is kinda annoying and Im worried it will burn out the fans before their time.
Also some time later I realized that the backlight on the keyboard didn't work and I couldn't get it to turn on manually. As well as the auto brightness adjust for the screen stopped working.
I have installed labtick and the keys do light up with that program (although I liked it when apple did it auto for me)
I read some threads here and really thought I had it with the reset the SMC. But to no avail. I also tried resetting the PRAM, which also didn't help.
I'm not sure If any of these problems are related or If this is just the most bunk MacBook Ive ever bought.

I have the new unibody 17 MBP 3.06. The unit doesn't get hot and I love it, but my fans run at a constant 3300-3500 rpm (istat and SMC fan control). The lowest setting on SMC is 1000 rpm I wanted it to run around 2000, but when I set it up the fans rev down then 1 second after revving down to the slower speed run right back to 3500 area. Is this normal? I thought SMC was to override the apple settings. Just 2700 rpm's makes a sound difference on my MBP. I was in a rush and forgot to mention that I just added SMC. I have had the computer for a month now and istat pro had it at 3500 rpm since I have gotten it and that is just surfing the net and at an idle. Since installing SMC Fan control didn't fix it I am wondering if I should take it in to an apple store or not?

I have a late 2009 Macbook Unibody that get extremely hot. From using SMCFanControl it tells me it's at 80-90 degrees celcius which to me is extremely hot. The fans also do not kick in at all when it gets at this level. When using skype, it skyrockets over 100 degrees celcius which causes my computer to slow down.
Is anyone else having this issue? Do you think it's a hardware malfunction?

I realize this probably wouldn't work due to the different smc controllers, but I'm wondering if the nice quieter 17'' mbp cooling fans would fit in the 15'' mbp's. Does anyone know if the fan sizes are the same? I know that the model #'s are only one letter off. The 17' mbp fans are quieter than the 15 due to having fewer blades(?) or a different design, and I think they actually spin at a lower speed. This would probably be super dangerous as the 17'' fans might not be compatible with or do a good enough job of cooling the 15'' mbp effectively, but it would be a cool mod. Anyone have info on the feasibility?

I have an older PowerPC G5 with dual 1.8 GHz. Recently I replaced the Power Supply and now the two fans on the back run at high speed all the time. There is no heat problem anywhere. In fact after an hour or two of running I opened the case and everything was cool to the touch. Not even warm! Is there a way I can get the fans to slow down?

Well my MacPro 2009 has this weird error where the fans will kick in and a restart wont restore them to normal a sleep cycle will though. It seems to only happen with OpenCL intensive apps but not Cuda intensive apps?? this may be random coincidence.

I noticed that on my macbook pro retina, i never heard the fans spin up.Â
I tried Prime95 to stress the CPU, temperature went up to 98°c and the fans stayed at about 2000rpm... I immediately stopped to avoid damages.  Â

My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed. No hard drive activity, no monitor activity. I swapped out the memory for the original factory mem - same problem - reset the switch... nothing.

I recently was given an old 2x1.8Ghz PPC G5 in order to build a personnal server but I have troubleshooting with CPU's temps that are really too hot (75?C with no app open, only Finder).
I know these temps are not that "hot" but I can't imagine what it would be when I'll open Safari, iGetter, iTunes, CyberDuck, Adium and Photoshop CS4...).
I first unmount everything, blown inside some bottled air to make sure there were no dust creating overheating inside and remount everything.
Installed Leopard (last OS installable on PPC machines), made the last updates possible and restart.
Everything is working well althought this CPU's temp is so damn high and fans's speed are still at 300rpm. I was looking for some app that would do the same as SmcFanControl for Intel based Macs but for PPC's ones.
After many internet searches on many forums I finally admitted there were no software able to set fans's speed, the only way was manually editing the AppleFan.kext integer's values.
WhatI did, reducing the integer values to lower rates (256x multiples), then restarted the Mac but nothing happens. As I check the changed values, they indeed are the ones I edited but the fans still are at 300 rpm and the CPU's temp 75?C...
Does somebody have any solution for that issue, I feel I checked everything that was possible but nothing seems to work.
