Hello, recently when i was on my PC i went idle for about an hour or so, i came back to see my keyboard leds off and my pc was still on but my GTX stopped lighting up as it usually does, i've had this issue before and it was just an issue with dust building up, i have tried blowing in it to remove dust and vacuuming dust but none have worked, if anyone has had this issue or knows a fix please help.
Cheers
