graphics card recognition

[Osiris01]

Hello everyone. I need some help i recently built a pc for a friend and hes having problems with his graphics card. when i built it, it worked perfectly fine and did so for about a week. he called me and said it wasnt working so i went over and reseated the gpu then it worked again. Now sometimes when he turns on his pc it will either load into windows or not recognize his gpu at all. I tried having him roll back drivers i tried having him reseat it but still nothing. Im not sure as to what the problem is. Im thinking either a messed up graphics card or maybe the slot on the mobo is messed up but i cant test his graphics card or mobo right now because im out of town for a bit. Any ideas?

Wait?

 It could possibly be driver crap.  Driver crap I know little about myself though.  You’ll get better advice from someone else about that bit.

 

The “sometimes” thing says connection to me though.   

If the motherboard is multi slot trying a different slot might be a test of the slot.  The card wouldn’t work very WELL in another slot but if it suddenly did work it could be an issue with the slot

Grasping at straws here one Fairly Low probability idea might be the eraser trick.  Use a pink Pearl brand pink eraser to clean the contacts on the gpu.  Make sure there are no crumbs from the eraser left.  Also make sure there’s not a hair or some other piece of weird crud in the slot.

start by double checking the slot is clean, blow some compressed air in there just to be sure, reseat it again making sure it's really all the way in there on both ends

then I'd say try different cables and ports on the gpu if you can maybe even a different display even a tv would be fine just to test

 

try a bootable usb to test as well see if it happens outside of windows environment, granted if it's throwing an error at boot then this would be pointless it'd clearly be a physical connection issue
