Solved Randomly get BSOD, Blank blue screen w/ updated GPU

[funkdoobie]

Hey, I built a computer for the first time and I recently updated my GPU from a Radeon HD 4350 to a Radeon HD 6790. When I played games w/ the Radeon HD 4350, I never got the BSOD and now that I install my new GPU, I start to get it randomly while playing games. I even replaced my 500w PSU to a 775w PSU, but that didn't help.

I also don't know what type of drivers I need for my graphics card. I just downloaded AMD catalyst driver and a profile from the AMD website

Can someone help me out here please.
I appreciate all the help I can get. Thank you.

I also have 2 small fans entering in the front panel and 2 small fans exiting in the back panel. These fans are also the age of the computer case which is about 4-5 years old.

I use windows verifier.exe and it said that dump_diskdump.sys never loaded. I don't know what that means. This time I got the blank blue screen again, but while watching youtube videos. Someone please help me
