Hi!
I recently started having really serious issues. When gaming, computer will randomly freeze and screen will turn into one solid color. Usually it is purple, but other colors are not uncommon (pink, green etc.). Sometimes when it crashes, CPU and other components will still be working for few seconds (I can chat via skype), just without picture
What is weird is that this is mostly happening with low demanding games like Minecraft. But I was not able to reproduce with Loadout for example (ok it is not really that demanding but it is best example one I have) and I was running FurMark for hours without problems with temperatures topping at 60 degrees C.
Temperatures do not seem to be the problem. This is log from SpeedFan several seconds before one of the crashes happened: (all in degrees C)
GPU = 51
System = 33
AUX = 39.5
CPU = -60 (this appears to be Speedfan having issues or something. It is always like that. HWMonitor shows correct temperature though so sensor itself is OK.)
SMIOVT4 = 33.5
SMIOVT5 = 33.5
SMIOVT6 = 33.5
HD3 = 27
HD1 = 28
Core0 = 42
Core1 = 38
Core2 = 35
Core3 = 36
Voltages:
Vbat = 3,31
Vcore = 1,14
+12V = 12
AVcc = 3.3
3Vcc = 3.28
5V = 5
VIN2 = 2.04
VIN3 = 0.76
I can't find real pattern of those crashes. Sometimes I can play for hour without problems, but sometimes it will crash few seconds after entering the game. It appears though that after "silence period", there will be several crashes one after another (game will crash right after entering it for several times).
Windows Event Monitor will only display "The system has rebooted without cleanly shutting down first..." message, so it is likely not something windows can control. I tried with latest drivers and windows update drivers, same story. It happens with Win8 and Win8.1 (recently upgraded).
Two additional remarks that might help somebody diagnosing: Sometimes after rebooting after crash, fan will speed up to maximum speed. And once when I rebooted after crash, I was greeted with "1 Long, 3 short beeps" and no picture. Reset fixed it though.
I was digging around a lot and I narrowed down problem to faulty GPU or faulty PSU not providing enough power to PSU. My problem now is detecting which component is faulty. Any idea how could I achieve that?
I don't really have any spare PSU or GPU so I can't really replace one just for testing. I have old 8800GT in other PC but I guess using that would not help since power consumption is smaller and it might just mask PSU problem?
My specs:
Asus P8P67 Rev 3
Core i7 2600K
8GB DDR3 1333Mhz Apacer
Gigabyte Geforce GTX 570
Kingston SSD (120GB)
Samsung 1TB HDD
650W PSU (Can't remember company name right now)
Thanks.
