GPU horizontal lines at login then freezes
Hi,
I am stumped here,need help to troubleshoot and finally arrive at a conclusion that what has to be done.
Few weeks back during gaming I encountered horizontal lines ,immediately after that my computer froze and there's the start,problem still persists.
Steps I took
Reseated my card,removed dust(normal cleaning).
Bought power supply tester Amazon.com: PC Computer 20/24 Pin Power Supply Tester With PSU ATX SATA HDD Connectors: Computers & Accessories
but it seems to show that
PSU graphic supply is working.
Installed fresh windows again but still issue remains
Did memory testing with windows memory diagnostic.
Now if I unistall my graphic card drivers,card runs as VGA adapter with no issues (limited functionality can't run games) but as soon as I install drivers the next boot immediately at login horizontal lines appear and then followed by freezing.
I ran my display on igpu ,everything seems to work fine all graphics n little bit of games n stuff.
Now I am confused and need help ,should I think that my graphic card is dead or before coming to that conclusion I should apply thermal paste n try that option.
I am also not sure somewhat power issue might be causing it but as stated above it was tested with at instrument and works fine. (Or do I need to check something else as well).
