Built new PC need help!

[samgwhitney]

Dont know if this is the correct place to put it, but it is a support forum so here it goes...

So this is my second pc I have built so I am not that new to building world. Anyway, the main problem I am having is with the gfx card (Radeon HD 7770). When I power up the computer the fan on the gfx card spins for ruffly 1 second then stops, and displays no picture. When I put the gfx card into my moms old Dell it runs and fine and it works and displays a picture. When i put her old gfx card (Nvidia 8600gt) the fan spins but I still receive no picture. Im not sure if its not getting enough power or I have the wrong parts or what. My computer parts are:


PSU XFX PRO550W
MEM 2Gx2|GSKILL F3-12800CL9D-4GBRL
HDD 1T|ST ST1000DL002 5.9K SATA3G
CPU AMD|PH II X4 965 3.4G AM3 R
DVD BRN ASUS | DRW-24B1ST/BLK/B/AS
MB MSI 970A-G46 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX
VGA HIS|H777F1G2M HD7770 1G R
CASE FAN|XIGMATEK XLF-F1253 R


If I could get any help it would be greatly appreciated.

Have you tried it in both PCIe slots? Your PSU should be fine especially if the Dell can run it. Sounds like a motherboard problem or a bad PSU. See if your mom will let you use the PSU to try in yours.
