Build has been working fine for 5 years, but in the last couple of weeks it started being weird.
Parts:
ASUS P7P55D-E Pro
i5-760
ATI HD5770
Coolermaster G750M PSU
2x2 GB Kingston RAM
The first sign of problem was about 3 weeks ago, when the screen turned black when I was gaming. Thinking it was a thermal problem, I restarted it and monitored the temperatures and it seemed fine. Went on to use the computer for half a day without problems, temps were ~60C for GPU and ~75C for CPU when running Prime95/Furmark. The next day, it crashed again (black screen/no BSOD).
This time i cleaned the gpu/cpu's heatsink. Over the next 2 weeks i started getting more frequent crash and a couple of BSOD related to the GPU (0x116/0x117). Tried different drivers old and new and it did not seems to have fix it.
Then 1 week ago, when I tried to start the computer in the morning, the fans power on for a few seconds and reboots itself. Tried removing components 1 by 1 until leaving only the MB/CPU/PSU, and it still reboots every few seconds. Then I placed the parts back in, and it seems to somehow work again.
The next day when it crashed again, it went into the same reboot loop. It still starts if I keep restarting it by using the switch behind the PSU to switch it off (power button doesn't seem to stop the reboot loop)
The next 3 days it seems to work without any problem, until today when i started it, it went into the reboot cycle and looks like it finally broke this time.
I have tried
-Clearing CMOS using jumpers
-Taking out BIOS battery and placing it back (check the voltage, was 3.3V)
-Reseating all connectors
-Running it with only the MB/CPU/PSU (same problem)
-Noticed that if I do not connect the 8pin CPU connector, it doesn't reboot itself but gives the CPU LED stays red.
-Took MB out of the case and sat it on a towel (same reboot loop)
-Tested PSU by starting it with a paper clip, tested voltage on all the cables.
This is also the third PSU, the first one(AMA AXE 650W) blew up after 1 year (Made sparks and smoke, blown fuse, tripped mcb/elcb) when i tried to start it in the morning. Replaced it with 700W OCZ, and that too exploded after 3 years. The current one also seems trip the circuit breaker when I connect it and turn on the mains power.
Any ideas if the PSU or the MB failed? Maybe something else? I'm planning to get a new PSU and test it, if that doesn't work, a new MB/CPU.
