I got the parts below and put a new gig together, installed windowns 7 and the thing works just fine first boot went well no issues.....untill I tried and connected the video card, I was using the in bord video till then...
I unplugged the power cable turned off the swicth and connected the 6950 to the pci express slot.
Plugged the power back and when I turned it on, the gig would start but after5 seconds or less it would just turn off and die.
also when I attached the card , the computer does not let me turn it on with the case pwer button, because when I am plug back the power supply and turn the power switch on the computer automaticly starts before I even press power....
Sometimes when I touch it it also starts wi th out me pressing the power button....
When I unplugg the video card I need to reset the cmos otherwise no boot...
After cmos reset and vga unplugged the computer works just fine using the onboard video only....
Any one have any idea why is that ?? All I can think is bad pci e but then again it starts but it dies later....
Dont know if it should start if the pci e is bad....
Please help

Hi and welcome to TSG.

A bad motherboard (pcie slot) is a possible problem, I would also look at the power supply aswell. You PSU is a good high wattage and a good brand however, even the good manufacturers sometimes have bad units that make it out to the buyer, so always worth checking.

It could also be the graphics card itself that is at fault, I would lean toward one of those 3 areas at the moment based on your description and the fact it works fine without the 6950 installed.

Quick question, did you plug in the power connector into the back of the video card?
