So, my computer has been running slow this past week and it freezes while gaming or watching videos on Youtube, and I have to force restart it. I installed a fresh copy of Windows 8.1 thinking it was a virus but the problem is still present. so I started taking out parts (gpu and ram) to see if it fixes and now I cant place my second ram dim because when I turn on the computer it starts beeping constantly without showing anything on screen and then restarts.
Specs:
Sentey BRP600 Psu
Gigabyte B85M-D3H
Intel i5 4440(stock cooler)
Sapphire R9 270x
2x4gb Kingston hyperx blu 1600Mhz
1tb WD caviar blue

How do you reset cmos?
Yeah, I went to windows update many times until I reached a point where there was one update that gets stuck at 4%.
And I don't think flash is up to date.
