Windows 7: BSOD's after Video Card Installation

BSOD's after Video Card Installation

I had an nVidia GTX295 that started going bad and was causing system freezes. EVGA replaced it under warranty with a GTX480. In anticipation of installing the new card I completely uninstalled the drivers, installed the new card and freshly reinstalled the latest drivers. I started getting BSOD's 12 times a day or more, all with different stated causes.

I ran all the standard trouble shooting steps like System Restore, memtest, System Files Checker, Norton Internet Security, Super Anti-Spyware, Malwarebytes anti-Malware and Uniblue Power Suite to clean and tune registry and update all drivers. None of this worked but then on one boot up I got a message that new drivers for the video card were available and I installed them and the BSOD's stopped for about 16 days then they started up again although I had made no changes in hardware or software to my system!

Now my system will go for hours sometimes with no problems then BSOD in less than an hour with no apparent cause & effect. I got a program called Blue Screen view and look at each crash report but at my level of expertise it's mostly all Greek to me other than it shows about a dozen different reasons for the crashes.

I built this system about two years ago and up until now I had only two BSOD's that never recurred. This is driving me crazy and ruining my computing experience. Any help would be greatly appreciated. I just hope I can get this written and posted before the next BSOD occurs...

There are many different fingers pointing in all different directions a lot of them have to due with corruption in the system. Run an elevated command prompt by going to start>programs>accessories>right click on command prompt and run it as administrator and type in sfc /scannow and let the system repair any integrity violations. I also saw a dump that was connected to Norton (that sounded kind of funny) anyhow it could be causing some issues as well...

Although it was one of the very first things that I tried to fix things I re-ran it as per your suggestion and got the results "Window Resource Protection did not find any integrity violation". If it could only have been that simple... Thanks for your suggestion anyway

I ran a CPU/memory stress test for an hour using prime95, :-[/url]

I ran the stress test for just over an hour without a hiccup. I monitored the CPU temps with Core Temp and my system didn't even break a sweat. I've attached a screen shot of the core Temp screen at the end of the stress test that show the highs and lows of all the cores.

Over the past two days I had a period of nearly 36 hours with no BSOD's and then out of nowhere a series of them one after the other, all with different messages:

During the periods of no BSOD's I had several total system freezes with no BSOD's while my son was playing Grand Theft Auto IV. Only way out was the reset button and re-boot.

I also ran 3 passes of MEMTEST86+ v4.20 with no problems. Someone else has told me that unless I run at least 8 passes it's no good. 3 passes took 8 hours so I haven't had the available time to run EIGHT passes!

During these periods of No BSOD's there was no apparent cause or reason of anything I'm doing when I get a run of them one after the other. This is so frustrating!
