I've had a couple of random crashes on my system in the past week or so. Before then, the system has been running solid for over a year. the only hardware change was that I installed a GTX 570 video card (which is dramatically faster than the APU's graphics for Second Life, which is what this machine was built for).
The system used to run with the CPU temperature the same as or half a degree below case ambient. Now, at idle in the BIOS, it's showing 10-11 degrees C above case ambient, and climbs fast whenever I do anything at all that's CPU-intensive (like run the Firestorm viewer for Second Life or run a multicore compile).
I pulled the GTX 570 back out of it, and then cleaned the CPU and cooler and reapplied thermal grease. Nothing has helped, so far.
System specs:
A10-5800K, not overclocked, running standard settings
ASRock FM2-A75 Pro4M motherboard
16 GB (two 8 GB DIMMs) Crucial Ballistix Tactical RAM
Xigmatek Gaia 120mm CPU cooler
Rosewill micro-ATX mid tower case with intake and exhaust 120mm fans
FSP Group FSP450-60GHS(85) 450W power supply
Noctua NT-H1 thermal grease
Hitachi 1TB hard disk
ASUS CD/DVD burner
Linux Mint 13 (no Windows here)
What's next?
Edit: I just checked the FSP power supply's specs. It's got two 12V outputs, one rated at 18 A, one at 19A. The GTX 570 card's recommended supply is 550 W with a minimum of 38 A on the 12V rail. That's just barely over spec for my supply. Could I have popped something? The BIOS voltage monitor reports the 12V supply at 11.8V.
Edit 2: The case is a micro-ATX mid-tower, not a mini-ATX or mini-ITX. It's wide enough to accommodate the Gaia, which sticks up from the CPU quite a long ways...
Edit 3: I just swapped in a known good, higher-capacity power supply. No change. At this point, I'm beginning to think I've got a bad motherboard or processor.
