GTX 660 Tech Help

[Persephone]

Hello, so I've recently purchased an EVGA GTX 660 and I've been having some technical issues. Prior to the 660, I had the GTX 260 and I had drivers issues all the time (it crashing, etc). I thought it was because of the GPU since it was my brother's old card & is pretty dusty. Anyways, I uninstalled the old drivers, put in the new 660, and then downloaded the new drivers from the web. However, sometimes there would be graphics lag that would crash my computer and I've gotten the BSOD twice. Also, after booting up my computer, I would get the "Disk read error" message & I would be prompted to restart by pressing Ctrl + Alt + Del. After restarting, I wouldn't get anymore errors. This does not happen every time either- maybe 1/2 chance. In a game on normal graphics settings, I would get slight graphic lag occasionally; it's not that big of a deal but definitely noticeable.

Yes, I have tried uninstalling drivers & redownloading them and I made sure I'm not using the onboard graphics.

I'm not overclocking it, I believe I have a sufficient power supply, & the drivers are correctly installed. What could the problem be?

Specs:

Mobo: ASRock Z77 Extreme4 LGA 1155

PSU: Corsair CX600 (600W)

CPU: Intel i5 3570K

RAM: 8GB

HDD: WD Velociraptor 300GB 10000rpm

OS: Windows 7 Ultimate

P.s. I'm not very computer proficient so excuse my ignorance :(

Fight be time to clean your computer of nasty junk files and what not. I like to reinstall Windows once a year, but that's just me. Run CCleaner for both junk and registry files, and do a thorough scan with Malwarbytes, see if any of your problems are related to that.

I don't think so.. there was an issue with the old GPU and that was when all the parts were brand new. Everything is now < 3 months old and I do use CCleaner regularly.

Have your tried drive sweeper? If that doesn't work after a fresh install of the drivers then its something more than the graphics card or the drivers.

Fresh windows install will always be good, but if you dont want to do something like that try CC cleaner, its very good software... If that doesnt help, let us know maybe something else we can think of that can help :)

Install a clean driver removal utility and completely remove any video drivers from the system, restart and install the new drivers .

Some people keep repeating how AMD/ATI drivers are bad, but it's completely baseless, people experience driver issues with both nVidia & AMD drivers all the time .

Don't forget to boot into safe mode.
