This week I've twice gotten a blue screen that said something about display drivers and BIOS while watching youtube/twitch. NFS Rivals experienced some bad graphical glitches with textures disappearing. Fallout New Vegas froze up and wouldn't respond at all and I had to reset the whole PC. I'm 90% sure this is videocard related but think it could also be a hard drive thing. Can probably rule out the power supply since I upgraded that last year in anticipation of getting a R9 290x but then didn't because I would've had to upgrade the motherboard as well.

Graphiocal Glitches and Freezing point more towards the Graphics Card then the HD ... any chance you have an old/spare one you could test?

With symptoms like that first thing I think of is overheating. There are also issues with files like (I think) atimag.dll and atikmdag.sys. I believe one theory was that updating drivers doesn't properly overwrite these files so you are using old versions which causes BSOD. That's just a theory though.

Have you tried doing a clean install of the drivers?

Have NFS Rivals and Fallout been acting up before, or did you just get them?

How old is your video card? And the hard drive?

Do you have a way to monitor the temperature?

I just had to replace my own card, and while I'm no expert, we could try to compare notes.

Nah I don't have an old one.

I should delete those files?

Haven't updated drivers recently but I'll try that.

No they haven't acted up before. Had NV since it came out and NFS since December.

They're both nearly 4 years old. Like I said, planned to upgrade last year but only replaced the power supply.

No temp monitoring but I'd imagine it can't be that hot watching youtube vids?

Go download BlueScreenView.exe, it reads minidump files and should point you in the direction of the offending Software/Hardware.

I assume the pink highlighted ones at the top are the cause? atikmpag.sys dxgkrnl.sys dxgmms1.sys

So what do I do with them? Delete and re-install the drivers and directx?

If those files were the source of the BSOD then you can guarantee the GPU or GPU Drivers are the cause here. Consider loading older GPU drivers if you can't find new ones.

I recommend looking for the latest driver updates for your graphics card. Uninstall any current GPU drivers along with Catalyst Control Center before installing new ones. Be prepared to use video output from the MoBo, just in case.
