Aero randomly crashing

hi there, sorry for reply so late, i took my time and reinstalled all my stuff so it took me some time...
i think that i will send my GPU to the store and ask for other card (if it possible)

i done some research and found that the issue of my BSOD at startup can be caused by some WIN7 update...
‏
KB2607576 if i don't mistake...however it far too late for me to just restore the system to the time before it was installed... =[
so i was wondering... can i just delete it? it not going to make my system unstable or something of sort? also do you know more other "problematics" updates that MC released? i had some experince with annoying ones.. however they all usually was fine when i reinstalled them each time after i formatted my pc so i have no idea what can cause it...

Yup =] (allready send my gpu)
but if the issue is relate to some MC update then even the warranty can't help it xD i need to know the update that give me the issues.

i guess that it was my GPU fault when it come to the TDRs , but the black screens on startup start to occur after i installed WIN7 updates.... i think that KB2607576 is the one to blame... but i don't sure, win7 have alot of updates after all xD

thanks

my issue was: after i formatted and startup the login screen, the entire screen will goes black or enter my monitor to power save mode for 1 sec , then i can see the cursor and there is a startup sound but all the desktop was black for some secs,
however after i installed some stuff the black desktop issue was solved but the "enter power save mode" is still there and happen randomly, i also notice this issue before i formatted my pc when i thought that i should try the updates that i ignored so far because i read that they gave hard time to some users, after i tried some updates i saw that my screen goes black on startup, but i thought that if i will install it after formate all will be fine.. now i see that it not... i need to fine that update that start this issue... but aside from KB2607576 i don't remeber the others =[

as for the pc run really slow issue and random TDRs and BSOD i believe that it was my GPU, now that i happened to test other GPU i 90% sure that it was the old GPU so one problem hopefully has been solved, through some users said that update KB2607576 made their pc slower, high their hardware temp, and done other annyoing stuff, so it may be realte to my issue as well

yup but these BSOD comes from the nvidia driver, the other black screens come for 1 sec after i start up my pc and then gone (and it happened randomly).

today i delete this update after i notice that my ram that usually was on 37% when i don't use it gone to 45-50% without any reason, after i delete this update the power saving mode issue come back.. only for once though, then i notice that my ram turn back to 37% and after another restart my ram stock in 40-+ %.... i really don't know what going on... my pc was just formatted =(

it must be either hardware issue or software issue (MC updates)

any chance that you know how i can detect the cause for it?

like to test if it hardware issue?

what it a DMP? down memory power? xD
where i can find it ?
