I am trying to get to the root of why my PC has started crashing after upgrading my GPU and PSU to a Radeon 7770 (Diamond) and Dynex 500w PSU. Game play is great, it's nice and smooth, I can max out the settings no lagging occurs. However even at lower graphic settings certain games will do one of three things,

1.Freeze for a couple seconds with sound continuing to play then it unfreezes and I'm able to play again.

2. Freeze then send me back to desktop with Display driver crash error/

3. Freeze and Blue screen of death with system restart.

My temp ranges on my GPU range from 55c to upwards of 77c

I have had advice kind of range from defective card to cheap PSU and was hoping with more detail someone could really narrow down a solution. Thank you for your time.


EDIT : I wanted to add this also its the MSI afterburner results I have no idea how to read this properly maybe there is something in there that can help determine what is causing the crashes
