Crashing - Tried Everything - PLEASE HELP
 

I am ready to EAT A BULLET over this - GEEEZZZZ!:censored: I built a machine less than 60 days ago and have had problems since day 1. Started with a simple black screen and auto-restart if I was playing COD WaW for 20-30 minutes or working in CS2 for an hour or two. Then as time progressed over the last month it has gotten worse. Now shutting down within 5 - 15 minutes once in Windows regardless of the program running (even while sitting at desktop). I have all updates to windows and hardware including drivers current. When the machine restarts it usually goes "blackscreen" and only goes into a loop of restarting. I have to cut all power and allow it to sit. Hitting reset or just powering off and back on does not work I usually have to allow it to sit for 10 - 15 minutes before it will boot to Windows. I have replaced the mobo, HDD, memory, tested video cards in another machine as well as formated and reloaded Windows Vista 64 about 5 times...nothing has helped. I have done more than this, but you are probably tired of reading by now. See machine specs below:

MOBO = Nvidia x58 Extreme Classified
CPU = Intel i7 920
Mem = 6G Patriot
Vid Card = 2 x EVGA 260 GTX (they are SLI'ed)
PSU = Corsair 1000w
Heatsync = Cooler Master V8
HDD = Veloceraptor 300G
OS = Windows Ultimate Vista 64

This machine should smoke...instead it CHOKES!!!!!!!!!! HELP PLEASE!!!!!

on next startup, press f8, select - disable automatic restart on system failure. That should give you a blue screen with an error code, instead of reboot looping. Look for an error code such as 0x000000 or a system file - such as nvs.sys.

I'm thinking heat could be an issue... Did you check the mounting of your V8? Which thermal paste did you use? Did you check the temps? Are all your voltages ok? Did you set them manually? Tell us a bit more.... :)

Where do you live?

Have cleaned and re-seated heat sync. Also used f8 to
disable restart. When disabled it still black screens with
no error code. Have seen 4 blue screens in 2 months.
Split second and no way to see code. I have checked
voltage and temps and all is perfect. Will stay on in
Cmos and bios as long as I want. Even took vid cards
out one at a time and tested in buddy`s machine.
Both worked fine. He has low psu so no way to sli
On his. Therm paste was cooler master. Cpu steady at
30-31 degrees C. Very confusing.

Sorry. I live in houston.

Can you get your hands on a different PSU?

It wouldn't be an issue of being underpowered, but even quality PSUs have issues some times.

Im thinking where the problem is slowly getting worse, its a peice of hardware dying. Sounds like a power supply problem, and especially where youve swapped out just about every part except for the psu. Borrow a psu, and run it with just 1 vid card if it cant support sli.

second the psu thing it sounds like 12v rail. get another psu if you can to try.that's just my take
