My screen shuts down while playing

Hello

I 've been having this problem for a long time but it goes off and come back !
My screen shuts down when i am playing heroes of newerth after like 10-30 mins its like theres no video output tho that the pc is still working normally , so i 've to restart my computer . my drivers are up to date and i just installed windows 7 ultimate x64 i tried everything i used chkdsk and memtest and i use Evga precision to check my graphic card temparature and it's fine ...

My specs are :

Windows 7 ultimate x64
Gefore 8800 ultra
Nvidia nforce 680i sli
Intel Core 2 Quad Q6600 @ 2.40 Ghz

Hmm this might seem like a stupid question but when u told me to test again with speedfan is there somekind of a tool in it that tests it ? or u just want me to play and see if theres overheating ?? (A)

I don't know or play the game so I don't know how good the coding is (hogs pc resources like GTA4 for example) so I am going to say that you rig is more than capable of handling it, perhaps the 8800 ultra is getting a little long in the tooth but it should be able to handle the game fine. The 680i were good boards as well.

This concerns me a little bit... I assume that you updated drivers after installing Win 7 and not before, and by up to date, you don't mean, the drivers that came with Win 7 Windows Update, right?

What version of drivers do you have and how did you updated the drivers? sorry, a lot of people do this the wrong way.

Did you also updated your audio drivers?

What kind of monitor do you have and is there a dedicated driver for it? this may not be pertinent but I remember having some issues, quiet similar to yours and it turned out to be the std/generic monitor drivers that came with win7 or at least, once I got dedicated monitor drivers, my problem went away so I always check... whether this holds any water or is related to your problem, I don't know.

Do you have your monitor set to sleep if idle [screen saver or what ever it is called]- Sometimes they can go to sleep if so lil touch of the mouse it is back on- And can do it in some games or even using some players to watch full screen videos what ever and the player or app what ever settings say do not let the monitor sleep. You would think playing and using the mouse the whole time it would not do it but they can in some games etc- I have had it happen to me in both xp and w7. I do not play this game tho- just saying is all.

Maybe it is a glitch or something and not supposed to go to sleep when in use but can be trying to or is doing so anyway. It is a fast simple test to turn off monitor sleep from display settings [or power saving I can not remember now] might fix it instantly- can change it before and after playing if it fixes your prob- good to go. If not it only took a sec to try any way..

Wish ya the best- see ya..:)

What kind of power supply do you have?

It's either you are overheating or the powersupply is overtaxed, which is likely.

sorry for the late reply @ richard : i downloaded the program isntalled and opened it while i am playing and the problem occurs nothing changed .

@ asta : Nope by the updates i dont mean the ones coming with the windows , i got like 4-5 different windowses after this problem started , and theres something else ( i dont know how but i dont have any problems for a few months then boom the problem comes back ) , its not a problem with my monitor 100% because i tried it on 3 different monitors and the problem is the same .. and no i didnt update my audi drivers !

@ ezeht : i checked what ur saying from power options and it is set to never sleep or turn off display and the problem happens if i open game or games with v.high graphics etc.. and i just noticed now that my GPU temp while playing is 75 while my Graphics card fan is set on 100% !!! .. there's only 3 things i didnt change in my computer since this problem started " Mother board - processor - power supply " ...

@ Matt : I think its overheating . but i dunno what to do i put a fan beside my computer on maximum power and still the screen goes off :s .

i will try changing the mother board / processor / power supply tommorow with my brother i hope there 'll be a difference .. Thank you all for tryin to help me <3 :)

hey guys i'm having the same problem and tried the speed fan test. i'm no computer guy but my GPU temp is at 93c and there's a flame beside it so i assume its overheating... how do i check my gpu fan?

In the BIOS, there should be an option for the fans, if its overheating, you may want to run them at 100% all the time or check to see if there is an AUTO option so it only runs them at Max when it needs it.

If its already set at Auto, then switch to 100%, your rig will get loud but its better than the alternative!
