I had recently air cleaned my computer as it had A heard of dust bunnies in it,and the gpu had stopped working. I got the 1 beep beep code and the whole disconnection shabang. Unfortunately my mobo doesn't have an igpu so I can't check to see if it's working at all. However I did pull a stupid and tilt the can while spraying it and it sprayed the gas on the mobo but the pc was off and unplugged. I left it alone overnight too but the next day it didn't work. I had plugged in am that you to see if the other one broke and it still didn't work. What should I do?
