I've got an unusual problem with my computer. When ever I reboot my computer it won't boot, I get a few beeps from the BIOS and nothing else, however if I wait for a few minuets the computer will boot perfectly.

I tried to count the beeps and I get around 7-9 of them; the first two are noticeably closer together than the rest. [Edit: I'm now reasonably confident it's 1 long followed by 8 short beeps. That would be a display related issue: http://www.bioscentral.com/beepcodes/amibeep.htm]

My BIOS is American Megatrends Inc and version P1.80, the Motherboard is an ASRock X58 Extreme (both according to dmidecode)

Here's an output from LSPCI, I'm not sure what else might be useful but I can provide whatever's asked.

Did you check you MOBO manual to see if the beeps mean anything? they usually have some meaning... –  Kyle Apr 4 '12 at 15:19
    
I recorded the beeps properly and listened a few times. I think it's 1 long followed by 8 short beeps. It might possibly be 10 very short beeps though, the first one does sound like a long beep. I didn't find any beep codes in my mother board manual but a quick search did find a page for American Megatrends: bioscentral.com/beepcodes/amibeep.htm According to this it appears to be a problem with the graphics card –  Benjamin Confino Apr 4 '12 at 16:00
    
Then test switching graphics card. If you don't have a spare, try just unplugging it and see if the beep signal changes. –  Daniel Andersson Apr 4 '12 at 17:29

Check your temperatures. I had this problem with a computer that ran far too hot, which didn't crash the computer (though it throttled the CPU down), but a restart would fail since the BIOS would not let the computer start at that high temperature.

This is consistent with that your problem goes away after a few minutes, when the components have cooled down (most likely the CPU).

Solution for me: install an extra fan.


Update after temp details became available: 60°C on your cores is not low by any means. The 127°C mark from temp3 is most likely just a sensor error.

60°C on your CPU might very well be something that the BIOS complains about. If you have a somewhat working CPU fan, the high temp is probably caused by bad air circulation in the chassi. Try installing an extra chassi fan.

First and foremost, it would be good to conclude that the temperature actually is the problem, though. Run the computer without the side plate on the chassi and monitor with sensors to see if the CPU temp drops to, say ~40°C. Then try a restart. If it works then, its most probably temperature related.

If the temp never drops that low, perhaps your CPU fan is clogged with dust. Google for cleaning methods and see if its efficiency goes up.

Now I have the beeps properly recorded I'll install a temperature monitor. –  Benjamin Confino Apr 4 '12 at 16:02
    
@BenjaminConfino: Do you have dual accounts at SU? :-) –  Daniel Andersson Apr 4 '12 at 16:04
    
Nope ;) I just wasn't paying attention and posted without logging in the first time. –  Benjamin Confino Apr 4 '12 at 16:08
    
Temperature details are loaded up and in the moderation queue. –  Benjamin Confino Apr 4 '12 at 16:52
    
Ok, I tried booting into diagnostic mode without the sideplate. Even on that low load temp2 was consistently above 60C. The air coming of the CPU felt nice and cool, but the fan looks EXTREMELY dusty so I'm going to try cleaning that and seeing if it helps. Fingers crossed :) –  Benjamin Confino Apr 5 '12 at 10:32
