Computer Freezing and Requiring Restart from Power Button

[CaddyQuinn]

Hello All,

I was wondering if I could get some assistance regarding a freezing issue I'm encountering. I'm currently on Windows 8.1 and have noticed that when I leave my computer alone it will freeze completely, including the screen. I was having issues where I would put it into sleep mode only to find that it booted back up later on and froze. Then I added a screen saver instead of putting it to sleep and the issue persists.

Any suggestions on what the possible causes may be? I've recently replaced the graphics card to a NVIDIA GeForce GTX 750 Ti and I'm unsure if the problems started after that.

Thanks for the help!

Try going into Device Manager and deleting the card. Then reboot. Windows will detect the card and reinstall the same driver you deleted. This is a support trick that works quite often. If it does not work at least it has the virtue of being very low risk.
