Hi!
System crash issue, in 3D performance.
i5 3570K (1yr old)
Sapphire Radeon HD7870 2GB GHz Edition (1 yr old), HDMI, temps around 60C.
Corsair HX520W (2 yrs old)
Asus Z77m Mobo (1yr old)
Corsair Vengeance 8GB DDR3 (1 yr old)
Windows 7 x64
When playing games, only when playing games, sometimes as in once a day or less, I get a sudden black screen, no cursor, [no signal] on TV. Lately, as in, since Saturday: once an hour it crashes, or more. I turned off the heat in my apartment and went full speed on all fans including GPU so it can't be heat related. When it crashes I can't even ping the computer, it's full freeze, no image, and I need to hold the power switch for 4 seconds to reboot. I clean the fans and radiators regularly. I never overclock.
Other troubleshoot: reinstall everytihng on SSD, no other disk or power hog. New/other drivers: same. Yes, it does crash more for some games and less for others.
But let's cut the suspense: if for testing I AMD Overdrive to 1200Mhz GPU clock, it crashes sooner. Stock clock is 1050Mhz. If I push Overdrive to the max (1400Mhz) it crashes as soon as I start the game, any game. I had fun trying that out a dozen times times. If I decrease the GPU clock to 800Mhz, it doesn't crash for all day and beyond. So it's the graphics card that can't handle its own stock clock rate, am I correct to assume that?
If it was the 520W PSU, wouldn't it happen even at 800Mhz GPU clock rate?
Thanks in advance! My concern is of course what part to replace as I have no warranty on certain parts (PSU), and more on others (GPU)
