I have to reset it .

If you need some spec's tell me and i will give it.
Please help
this problem is getting verry on my nervs :|
 
there are many causes for computer freeze-ups, but most are linked to drivers and/or other system files. does this problem you are experiencing happen in all games or just a few? have you installed any updates or new drivers for your graphics or sound card? did you install drivers for the keyboard or any software that shipped with it?

the more we know about the computer the better, so definitely post up the full system specs (CPU speed, RAM, power supply etc..) and include which operating system you are using. with this information we may be able to help you diagnose the problem more efficiently.
 
Hi , Don't watch my typing .
Its because i have a nother forum working also ad this problem i just copyed.
If you have questions.

Normally yes . i had it a few time's when i got windows 7 .
i installed back vista i don't get it in vista but if i play a game it just freezes randomly .

Its a desktop
No mark
I put it together myself .

moderboard is a asus p5e64 ws professional.
Ddr 3 4Gb = Kit 2x2 gb ram
Intel processor Core 2 quad q9450 @2.66 ghz
Nvidia Gtx 295
thermaltake toght power its 850

I try to play the gamed Call of duty WOW
And i got it whit windows vista home premuim

like i tryed an old game Age of empire's 3 a while ago and it also froze :s

tryed a memory test
no problems found .
and i have driver genuis and i did a scan and no up to date driver's where found.

Temp card :

Nvidia geforce gtx 295
1* Value: 53 ° 2*52
1* Min : 50 ° 2* 48
1* Max 54 ° 2*52

Yes but i don't think that their is the problem
Because the fan rotate's now at 25 %
If i use riva tuner i can place it to 100%
So .

But the bizard thing is if i let my computer download somethings
And i leave it on for the night , the same thing happens to
My pc is still on but my keyboard is off and i have black screen .
+ My screens say's : No signal .

I have turn Sleeping mode off ...
Normally he most stay on for the whole night .
And if i look at controle : it say's windows 2 have shut down wrong
Or do you know something better (Progam) To see the error he is doing .
