My computers beeps once therefore no problem but after 5 minutes on IDLE it crashes, I restart then press shut down then right as it begins to shut down BOOM another crash, None of this was a problem until I cleaned some thermal grease off my mobo which is a Gigabyte F2-A88XM-DH3. At first I thought it was a hard drive problem, but after it crashed on both drives I knew it wasn't the drives, I don't know what it is because of the one beep please help!!
