Oldish pc. Win 7 pro on one side of partition. Gpu is Saphire Radeon HD 4870 2g and Mobo is Asus n13219
Tried to open up Warframe, screen suddenly turned to blue and white checker board pattern. Was able to close game and restart PC, but still messed up, weird white boxes and lines. Shut down completely.
Waited many hours and started again, same but PC suddenly turned off. Opened up PC. Cleaned out much dust and dog hair I never knew was in there. Fist fulls of it. PC starts now, but screen is still messed up and won’t go past bios. Tried to reset bios to defaults, made it worse.
Very desperate to fix, important info and pics on PC plus can’t afford a new PC.
Is it Mobo or gpu? Both? Can I get cheap and compatible replacement?
Ty in advance.
