wow ... so far so good with the video card driver ... im suprised ... that seems to have solved it for now ... ill find out more later. thanks.

 

nice one glad it works (i do like my games as well)

 

If the problems comes back, try these things:

1. Run a memtest, at least five or six passes
2. Check the temperatures right after crash

 

Welcome to Majorgeeks ipfunny!

Your 12v reading is a bit low on your PSU. But software volt readings can be unreliable. Do you have access to a multimeter? I am glad the driver change has helped you, but if your Power Supply Unit is not working properly, or is underpowered, you may be in for a word of problems down the road.
