So here's my issue: My PC sometimes fails to boot (monitor just turns black) and reboots itself for a few times. Also, when I turn my computer into sleep mode, and I tried waking it up (moving the mouse, pressing the keyboard) it won't wake up. What seems to be the problem? Thanks in advance!
Note that this occurs only once in every three times I start my pc. If I get to start it, there seems to be no problem at all.
