hey, I recently bought a Geforce 6600GT, and a new PSU (from 350watts to 600watts) but when I try to play a game I can play it online for about 3 -4 mins and then it just crashes to my desktop, first of all I throught it was a graphic card, so I sent it back and got a replacment but I got the new one today and it does the same god dam thing. Does anybody have any suggestions on how to fix it or what to do my pc specs are below

Epox EP-8KKMEI
AMD Atlhon 2600+ (1.95ghz)
512MB Of Ram
660W PSU
TV Card,
Sound Blaster Live
80GB Maxtor HD

I have tryed updating the driver, I have flashed the bios to the lasest version but still nothing, any help would be great

Thanks again

David

What game? or all games?
does dxdiag show anything wrong? (what version of DirectX?)

Are using the drivers from NVidia or from the graphics manufacturer?

Yep i am

the game is any, quake 4, Cs:S farcry you name it, it happens

I got directx9c which is all working correctly no problems reported from dxdiag

I also dont think its a overheating problem my max temp goes upto a max of 50degrees,

try enabling/disabling fastwrites

Where are you getting the temps from? Is that "max50" from a log or where?

And what's the brand of the PSU?

I am getting the temps from a monitor which came with my motherboard, and the psu is WinPower (i think 660W)

Maybe the gfx card is overheating? I have the exactly same card you have and it died on me a few days after I've purchased it. Thank god I had warranty and got a brand new one. I've upgraded my PSU and it has been working fine since then.

I recommend you to check the gfx temperature and CPU temperature after you've played a couple of minutes. A little anti-virus, anti-spyware and defrag might help.

Are you overclocking? Some games will crash if you are overclocking. Same goes to the graphics card too.

I am pretty sure I am not overclocking Bios says its 1916mhz but in windows it reports 1.95ghz

also my gfx isn't overheating when the game plays I enabled a special monitor, and it doesnt come up yet

You might check in the display properties to see if the video card is overheating. Try and set it to output a log file if that is possible. The motherboard utility will only monitor the CPU and motherboards temps NOT the temps on the 6600.

Also use the official nvidia drivers, if you are not already. Try using a utility called "Driver Cleaner Pro" to reinstall your drivers, google it you will find it. Make sure you follow the instructions carefully. Also make sure you have the correct and the latest motherboard drivers, as these things can happen with outdated motherboard drivers.

But I suspect the power supply, you might try using 3dmark05 and run it in a loop and see how long it takes to crash(if it does at all.) If it crashes at a specific point all the time it's probably the card, if it's completely random it's probably the PSU. Although, that is not an exact science.

I'm assuming of course, that this did not occur with your previous card.

Not with my MX4000, yeh

Also I did send the same card back becos i throught it was fauty and I got the new one yesterday and its got the same error,

and I have tryed driver cleaner pro and its no help

and setting Log to file I cant seem to do that

My temps when Idle running mozilla msn etc..

VCore: 1.680 V
VAgp: 1.488 V
+5V: 4.919 V
+12V: 12.160 V
Vio: 3.280 V
VDimm: 2.624 V
VBat: 3.168 V
5VSB: 4.921 V

System temp: 32°C/89°F
CPU temp: 39°C/102°F

So does it crash with another video card? or just the 6600?

just with the 6600

Try reinstalling directx.

If it's just the 6600 then I'm thinking the card. Does the manufacturer have anything on their page about it? I would probably return the card for one made by another company.

I already returned it once saying its faulty, but it isn't the card its my pc since i was getting the same sytoms with it

also I have tryed reinstalling directx but no luck
