8800GT Alpha Dog Problem

[abumuqaatil]

I have recently purchased the Alpha Dog XFX 8800gt,and I seem to be having problems. They are :

1. Fan is always on low even under load, except on boot-up for 1st 3 seconds then goes to low
Rivatuner 2.06 doesnt help either.

2. Under Vista Crysis couldnt last for more than 10 seconds, display driver would stop working

3. 3dmark 06 has never finished under Vista. same prob as above.

My P.C was Overclocked, changed everything to stock still same problems. GFX card always at stock.
600/1800

What I have tried.

1.Drivers 173.xx that came with card, 169.02 and 169.04 = still no change !!

2. Format my HDD and go back to XP = Same problems except 3dmark 06 always gets bad artifacts on
Last SM3 HDR3 test which is the Antartic one, sometimes PC locks up altogether, says O.C failed on reboot
but when I change everything to stock still I still get bad artifacts on last 3dmark test ???

3. Unplug all extras from my PSU = still same problems.
4. All these tried non Vista and XP, XP slightly more stable but still same problems

BTW I have an Intel 2140 on 3GHZ OC 1.6 when stock and 2 GIG Corsair XMS DDR2800, Asus P5K Mobo
Also On GFX box it says recommended 500W PSU = My PSU is a thermatake 480W peak 550, with no native 6 pin PCIe
cable, So i use adapter , 2 four pins into a 6 pin, into one PCie 6 pin slot on card, which came with the card.

I think I have one of 3 problems.
1: Need more powerful PSU
2: Driver related problem
3: Faulty card

PLEASE HELP

It could be something in the system or the video card its self. I dont think its a driver issue as we have been messing with the 8800GT here for some while doing benchmarks and such. 3DMark06, Crysis, Bio Shock, Lost Planet and many other games with out problems. Are you able to try this video card in another system?

How many amps does the 12V rail have in your PSU?

Do you have another video card you can test?

Try testing it in another computer as suggested.
