I have an AMD FX 6300 on an ASRock 970. We built the computer in the spring and have had it working since (There have been some problems in the meantime that mgiht be relevant, I'll get to them later). Last week, the computer stopped working entirely: I power it on, and after about 10 seconds I get a 5-beep error code. Nothing is POSTed on the monitor (the monitor doesn't even power on to indicate it's receiving signal). I can't find my mobo manual anywhere, but cursory googling tells me that 5 beeps is a processor problem. We've tried booting without hard drives or graphics cards, problem persists. There's no obvious damage to the CPU or board.

Additional background:

• Since the computer was built, I've had a very strange bug. I discovered it when I was trying to install a Linux (Mint KDE 14). As weird as it sounds, if I sit too long in anything EXCEPT Windows, the monitors stop receiving signal. This includes sitting in BIOS.
  
• For the past month or so occasionally after rebooting, Windows tells me that one of my partitions is corrupted and needs to be chkdsk'ed. I let disk repair run and usually that's the end of it for a week or so. However, this problem is made worse by the above, because chkdsk requires me to sit outside Windows for several minutes. However, it seems that even though the monitors stop receiving signal, the computer still runs, because chkdsk finishes even after the signal goes out.

I had the same error code of 5 beeps. I swapped processors, and had the same error code in my case. The 8150 tested fine on an m5a97 in another case.
Thankfully, I continued reading replies, and after despairing, swapped cases. I'd been working in a Raidmax Scorpio, which doesn't have the best reputation. After rebuilding in a quality Thermaltake Armor case, the system worked pefectly. Hooray!
