My Mum has just turned on our family computer- an iMac G5, 1.9ghz 17" (first model with built in iSight).
It gets to the grey screen with the apple, with the loading icon below it, then after about a minute the fans turn out pretty loudly, and it goes no further, just stays on the grey screen.
I have an iBook 500Mhtz PPC G3, 384 RAM, 10GB HD, Dual USB. Several months ago, I opened it up and it simply would not start up. No start up sound, no noise from the fans/HD/anything, motionless. Completely dead. I've held (many times) the PMU, and tried almost anything. Is there anything else I can do to get it to AT LEAST turn on? The battery is dead, and the charger is fine, but the battery won't charge. I tested the charger on a PB G4. I'd rather sell the whole computer as a working computer. I figured I'd get more money that way. do I need to sell it for parts?
View 3 Replies View RelatedMy parents recently bought an iMac. Yesterday my mom was playing a game when the computer froze. Neither force quit or holding the power button was doing anything so in her frustration she unplugged the system. Today, after plugging in the system again, it won't turn on.
I press the power button on the side of the wireless keyboard and the green light on the keyboard turns on for about 3 sec and then starts flashing. No fans start up and the screen does nothing.

My fans are constantly going on my g4 powerbook and the noise drives me nuts. I do all sorts of work - graphics (CS2), music recording, multimedia... but even when I am just not doing anything intensive the fans are on.
The fans are at full speed now and the temp reads 37C / 98F. I've used an icurve since I got the machine.I've put up with this noisy sound for a couple years now. One person said I need to clean the air vents, like dust is causing the noise. Does anyone know about this?
its a g4 titanium powerbook 867 mhz 768 RAM (ancient I know but it still works!)
My Mac Pro started having issues about 2 weeks ago. The screen would go blue every now and again for about 3 seconds and then go back to normal. It kept doing this off and on.
Two days ago the Mac Pro started making a buzzing/humming sound, loud enough to hear in the other room.
I shut it down and tried to fire it back up and it began making a clicking noise, then the humming came back. The screen froze at the grey screen and did not show the white loading wheel.
I've swapped out the drives and still the same.
The Mac is about 2.5 yrs old and I use it for video editing (FCP) and photo editing (Adobe CS3). I've never had any issues until now.
Macbook Pro can't start up beyond the grey start up screen. There's a spinning wheel and bar that moves to 1/4 before Macbook Pro shuts down automatically.

I'm trying to fix a friend's G5 desktop, 1st generation. 1st LED comes on, 2nd LED comes on when I press start button. Power supply voltages are correct. Hard drive runs, but fans don't come on. I have power to fans. 5 and 12 volts. No beeps. Pressed SMU button as well, and nothing changes. Don't see any bulging caps. Someone else changed a few before I got it. Also jiggled RAM chips.

i Was surfing the Internet and all of the sudden my computer turned blue. I closed the screen to 'refresh' it and when I opened it back up some of the pixels seemed to be missing and then it started beeping at me in increments of 3. I **** it down and tried to restart it. when the screen booted up it still seemed to me that the pixels were screwed up. I've managed to get past the blinking image of the earth, however after that disappears a grey screen comes up for about a minute or two and then the entire computer shuts down. This is in the middle of my finals and I cannot lose any of my work!

I am currently experiencing problems booting up my imac 17-inch, 1.6GHz (2004 model I think). When I hit the power button the machine starts but the screen rmains black and after about 3 mins of this, the fan goes into overdrive! The only way I can turn the computer on at the moment is to remove the casing and use the on switch located inside the the machine, although this is no guarantee it will work, sometimes it does but the majority of times it will be the same black screen as before. All I am waiting to hear is the part in the top corner (hard drive~?) to click into gear and then it's fine, and the machine seems to work perfectly. But this is not a solution and I fear it is only a matter of time before the machine just explodes altogether

I purchased my Macbook in 2008, roughly July.
My fiance unknowingly shut down my macbook in the middle of start up. Before that it was running perfectly fine, I had no issues. After my fiance stopped the start up, the macbook won't turn on. It'll load up to the grey loading screen (example here)... It doesn't make much noise as it starts up either. I have all original discs that came with the macbook, if that helps any.Â

Went to turn on my Mac book pro 2011 or 2012 and it went to the grey loading screen with an apple, spinning gear and a loading bar. Once the loading bar completes my Mac book just turns off. It just keeps doing this, I tried to do a safe boot, but once it was done that it turned off and continues to do this circle of grey screen loading than turning off.

My MacBook Pro (The oldest one, I believe) won't start. After OS X 10.6.5, it will sit at the grey screen with the spinning gear. Safe boot does the same. Verbose mode shows it stuck at "vmnet: netif-vmnet8: Adding protocol 2." I can boot off the install CD and single user mode

View 10 Replies View RelatedWhen i start the computer and the grey screen comes up with the apple logo etc., a grey "loading" bar has started appearing in the bottom of the screen. Takes a few minutes for it to go away. In the meantime the computer gets very hot and the fans are up to 6000 rpm. Then the os starts up, and I cannot download anything, due to the fact that it thinks my harddrive is full, though i have more than 100 gb of free space.I cant even download the 10.6.2 now due to the harddrive appears to be full

My computer started having problems some two weeks ago.First it was very slow then it blocked during the use of Photoshop.At that stage I used Apple jack to test and solve the problem and it worked.But two days later the problem came again as a verry slow start-up.I checked the disk and there was no problem signaled.I tried to boot the computer on the installation disk in order to execute the Hardware test...The test gave the folowing error code: 4HDD/11/40000004:SATA(0,0)Â

I have a Macbook Air. I thought I had lost it, so I erased it from Find My Iphone. Then of course I found it, my computer was completely erased. When I started my computer I hear the chime, but then a blank grey screen (no apple). I have tried every start up command and reset. I have tried Command R, Option, with and without connecting an Toshiba hard drive that has my computer backed up. I have tried disconnecting everything more my computer. I'm not using an external keyboard.Â
Again, when I try command R, option, command n, D,T, the shift button, etc. nothing really happens the screen is still grey.
just installed 10.5.6 on their last gen. iBook.She left the iBook plugged in to the mains and came back to find that the iBook was alternating between the grey Apple screen and a light blue desktop screen where she could see the cursor. Sometimes it would also switch to a blue screen without a cursor.
I've tried holding shift during startup - no effect.
I've tried rebooting NVRAM - no effect.
Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.
Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.
I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.
So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.
I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?
I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?
I'm really confused by all this, and would appreciate any help I can get.

Fairly new MacBook Pro with OXLion. When I try to turn on the computer, the startup noise and screen appear (grey loading screenwith apple icon). A loading bar at the bottom of the screen fills about a third up, then the computer shuts down again.
