Computer freezes while gaming.

[Syredor]

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

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.

I would reinstall the Intel graphics driver for the integrated graphics, or just purchase the graphics card you mentioned.

You may have uninstalled or damaged the integrated graphics driver.

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

I already tried reinstalling the intel graphics drivers. So just no gaming until I get a new video card then? And yes, on-board graphics atm.

Windows system log should tell you what caused the freeze....have you looked in Event Viewer ?

Yeah, I checked the logs, and there's nothing out of the ordinary. All the errors just say that the computer was shutdown unexpectedly. I have to hold the power button down to shut it down.
