The system:
Motherboard: MSI 890FXA-GD70 - http://www.msi.com/product/mb/890FXA-GD70.html
CPU: AMD Phenom II X4 965 3.4GHz
GPU: Sapphire Vapor-X 5770 (ATI Radeon HD 5770) 1Gb - http://www.sapphiretech.com/presentation/product/?psn=0001&pid=305&lid=1#
PSU: Thermaltake TR2 600W - http://thermaltakeusa.com/Product.aspx?C=1247&ID=1898#Tab0
Windows 7 Prof 32 bit (clean install, nothing else installed but drivers and games for testing)
The problem is that while I'm on Windows on non intensive tasks such as web browsing, periodically I will receive "Display driver stopped responding..." errors after the PC freezes for about 4-5 seconds then recovers.
When playing a game, this will happen more frequently, and it will send me to a Blue Screen crash, often citing atikmdag.sys or dxgmms1.sys for the cause of the error, although I've seen many more windows files as the cause (like tcpip.sys, ntfs.sys, etc).
Recently I started switching components between other machines to weed out the problem, but the only thing I can replace is the GPU card with another pc's nVidia Quadro FX 3500. With this card the errors still keep happening, except they behave differently: I never see the "Driver stopped responding error..." on Windows, only when playing games it'll freeze for a couple of seconds, audio gets garbled and then it recovers with no error messages. For a second after the freeze I notice that the Frames Per Second go all the way down to 1 (the game until then is steady at 50-60 fps).
I've yet to try swapping out the CPU and PSU for other working ones (I don't have ones that are compatible with the mobo, and I don't want to buy new ones just for them not to be the problem), but now reading the PSU guides and the importance of 12V rails and everything else I got the doubt that the PSU may be the problem (and also the PSU is the only thing I didn't research when buying the system), I just need anyway to confirm this, and if so, which PSU would be the best to replace it?
I plan to add to the system another GPU or upgrade to a better one when I need it (now almost every game I play runs smoothly on max settings) and maybe add a fan controller (I got 4 case fans in there).
Thanks for reading and hope you can help me with my problem.
