Recently, I took my video card out of my system(giving to friend as I'm buying a new one) and now when I try to play games, be it Diablo 3, League of Legends, Emulator games, or Rift, my computer freezes after about 5-10mins of gameplay. The system worked great before I took the card out, never having a single problem. I defragged, disc cleanup, ran malwarebytes, ran virus scans, and it was all clean. So I downloaded HWmonitor, and ran prime95 for an hour and my cpu temp never reached above 60degrees celcius and it didnt freeze. So I have no clue what the issue is. Computer specs listed below
Windows 8.1 64-bit CPU
Intel Core i5 3570K @ 3.40GHz 35 °C
Ivy Bridge 22nm Technology RAM
8.00GB Single-Channel DDR3 @ 666MHz (9-9-9-24) Motherboard
ASRock Z77 Pro3 (CPUSocket) 32 °C Graphics
ASUS VS228 (1920x1080@60Hz)
Intel HD Graphics 4000 (ASRock) Storage
931GB Seagate ST1000DM003-9YN162 (SATA) 28 °C Optical Drives
hp DVD-RAM GH82N Audio
High Definition Audio Device
My old video card was an AMD Radeon 6750 core edition. And I did uninstall the drivers. Also my two RAM sticks are both 4gb, but one is 1600mhz and the other 1333 or w/e the speed is for that range.
Basically I just need to know why it could be freezing. Because it should not be.
So now your PC has no graphics card in, when you game you are using the CPU on-board graphics? Will prime95 use the on-board graphics? I suspect the problem is your CPU is getting too hot when on-board graphics are used.
When you get a new GPU, everything will probably be fine again
