gpu issue help!

[czguy]

hello!
so i have a zotac gtx 970 and it used to run fine but it started to like black screen when i entered a game and played for like 30sec to 1 min and i then have to force reboot the pc
then one day it just started giving black screen all the time . i tried the pc with integrated gpu and it runs fine but when i put the the 970 in the pc it just shows black screen .. i can hear the pc post noise and the PC runs while the GPU fans spins and everything works but no video and just black screen

also when these issue was ist occurring i tested the system with gpu and cpu stress test for 30 min and everything was fine no crash. good temp
also i tested the vedio card memory and ram test both passed
so why is this happening .

before the issue was occurring i did all the possible test and stress test and it passed

also i wiped the pc for possible driver issue and using a new hard drive still no result

it would be very helpful if anyone can help me with this as its been 6 month i cant get any job done and well no gpu in the market here

Do you have multiple pcie slots on your motherboard? Although it is most likely a x8 or x4 slot... it's still worth a try.
