I know that there are heaps of posts with a similar issue, but none seem to fit mine.
I've just built a PC for my friend on a budget, when I plug the graphics card in and try to start the PC it takes forever to get through the mobo splash screen then goes to a black screen with a flash underscore.
This only happens with his graphics card. It works fine without it plugged it, it works fine with my HD 7850 plugged in, and his card works fine in my rig.
My guess is that it's the PSU, but I'm not sure.
Specs are:
i3 3225 3.3GHz
Overclocked Geforce GTX 650 TI
Corsair 8GB 1600MHz
Seagate Barracuda 1TB 7200RPM
Huntkey Green Power 550w PSU
Intel BOXDZ77SLK50K ATX mobo
a c 95 U Graphics card

it's your psu. try another psu in the build... i bet the problem goes away. If that doesn't work (and it should) i'd try to clr_cmos and see if the gpu loads up... that said i'm almost 100% certain the problem is the psu.

sidenote, even if the problem doesn't go away i would throw that psu out before it burns your friend's house down. that psu is a legit fire hazard and i'm surprised you found it for sale anywhere. if you don't believe me read this review. bad psus are disasters waiting to happen. i don't think your friend will thank you for burning down his house or blowing up his computer. http://www.hardwaresecrets.com/article/Huntkey-Green-St...

seriously dude, i know you tried to do your buddy a solid by building him a machine, i would man up, drop $40 of your own cash on a corsair CX430 psu and apologize for making a bad choice on the psu.

It was my fault for accepting a change in part over the phone. I was in a rush and didn't have time to research. :(  That'll teach me.
