I'm new here and have a problem. I hope you guys will help me out. As far as I can see you're helping alot of people and doing a very good job. I got a gtx 295 for my birthday (june 3rd). Windows loads just normal, but when I try and start any 3D application (3D mark vantage, crysis, ...). My pc reboots before the program even starts. This only for a couple of programs, untill yesterday crysis warhead ran just fine, so did cod4. But when i played warhead, the pc reboots too now. I have the latest 185.85 drivers, a 1000 watt power supply, core 2 quad q9450 (2.66 ghz)and 4 gigs ddr3 1600 mhz. I use Windows vista 64 bit home premium. This happens when i installed my new gtx 295 card with my previus card (9800 gtx) everything run just fine. Sry i cant give you guys more information untill this evening (local time belgium). If you guys have any questions i'll try to answer them (i'm working at the moment, so dont expect a swift reply). Thank you guys for your help and i hope to hear from you soon.
Check temps. If they seem to be ok, and this keeps happening, make sure your card is hooked up right with your psu, sometimes a 6 pin has lower power out on multi connects coming from the psu. It could be a power issue, not that the 1000 watts isnt enough, but your particular hookup isnt quite right. It could also just be a faulty card.
Usually, if its played fine in the past, it isnt drivers, unless youve noticed a change in performance since you changed drivers. Unchanged drivers, my bet is, faulty card, heat or power connects
If your PSU has multiple rails, you might not be load-balancing them. Of course, it's hard not to when you can only use one type of connector. Either way, you should have at least 4 6/8-pin connectors. Keep one of the original plugs in and replace the other with one of the available connectors. I'm just shooting from the hip here lol.
When I install my bfg gtx295 I have a similar problem, it's happen because the 295 need lots of power, too resolve that I used 2 separate 12volt rail on one side for the gpu I think, and 2 separate 6 pins for the fan. After that everything work really well.
First of all I want to thank you all for helping me. Second I have an epsilon 1010 power supply, but I dont really understand the rail thing (sry bit of noob on that part) But I used a 6-pin power cable for the card and a 8-pin power cable for the card. They have multiple connections on the cable but I'm not using them, is this what you're talking about?
As for my temps: 50°C idle, 75°C/80°C on load (this is stock fan, I can set the fan speed to 85%. In that case my temp never goes over 70°C).
Temps seem fine. If you have your documentation for your psu, see if all your 6 pin connectors are the same for power . One may be rated for higher power output, and that maybe where the problem lies, if you dont have that particular one hooked up to your card, and a lessor/weaker one is, and your card could be underpowered.
Its either that, or your card may be faulty
