Aero randomly crashing

hi there


i have some issues here
i had alot of black outs that killed my old PSU and GPU (which was Geforce 295 gtx from Gigabyte)

i replace them with Geforce 295 GTX from XFX and AcBel R88 1100W

after that i notice that the win7's AERO turn off often (which never happened to me before with this build since i had it.. and i had it for 2 years allready...)

i thought to myself that it probably issue with my OS and because i planed to format anyway i thought that i have nothing to worry.
then i reinstall Mass Effect 2 to finish its DLCs before 3 will come out and saw that the game crash for me with TDRs and black screens, i played ME2 two years ago with that pc and had no issues at all....
i tried to change my driver (which was the 295.51 beta) to other old drivers, i tested the 260.99 which usually was stable for my older 295 gtx card and the issue still was there.... i tried 3 more drivers and still no luck...

then i formatted and notice that the pc working a bit slower at some parts, and after each 20 mins my Aero was turning off again before i install any drivers, it never happened to me in this pc with my old GPU and PSU and i formatted it really alot. after that i installed the 260.99 driver again for a test and let win7 to test my system points and in the middle of the test my driver crash and when i tried it again i got black screens and had to forcely turn off my pc! after that i fully delete the 260.99 and installed the 295.51 beta again..., the sudden aero issues stops and win7 test my hardware without TDR or BOSD, But again when i play different games i get ton of TDRs! i never get such number with my old 295 gtx, what do you think it is guys? maybe it my CPU?

does Gigabye was way better then XFX? we talking here about the total same cards... it just other brand...

Thanks for the replay :). However I 100% sure that it hardware issue and not driver issue, I never OC my system and I not plan to do it too. By BSOD I meant to black screens and not blue... does it count? , it happened mostly because of the video driver , I think that it hint that the driver is not getting along with this video card..

Btw my pc is reformatted again atm and I don't have either the log anymore and still not install any program on it so i don't think that I can send the file atm..

Umm did someone marked my case as solved? O-o cause it not...
And I don't see JMH replys anymore...

Oh that explain it xD

And yea, because I worte it in hurry from my iPhone I thought that post 1 made alot of misunderstooding so I decide to completely edit it from my pc :)

Thank for your help though

Thanks
I want to rep you but I can't do it atm because I'm using my iPhone
So I will do it later

Btw where you said that I can see the report about the BSOD case? Cause I can't see it at the event log

Nope , but suddenly when I restart my pc my screen either turn off and back on or either I have black screen with only mouse for a few seconds before I can see the desktop.... My pc only been formatted ysterday what can it be? My video card?
