Recently one of my ram sticks failed so i removed it and put in a working one to boot the system. It would give me one beep with no signal . I reset the CMOS battery to try and get it to boot up it did . Then when I was normally browsing my pc suddenly stopped working and it was stuck i couldn't do anything then it started beeping 5 times. When I restart it works fine for about 30 min and after that it again suddenly stops working and beeps 5 times . I'm not able to figure out what the issue could be? ( I have an asrock Mobo )
