If I could find my mobo's manual
Okay, it beeped again only one short beep alone.
I opened it up to clean it, turned it on, nothing, black screen.
Tried again, it worked, but it gives OC Fail on a black screen with text. I don't do overclocking, what does OC fail mean?
If I skip that message by F1, I feel PC is lagging more than usually. Also, I think the GPU's fan is moving too slow.
