Question Why my PC crashes even after I disabled overclocking?

Oct 18, 2019
I recently bought a new PC for gaming. It was working totally fine. One day I opened the bios of the motherboard by pressing "Del" while booting and from there I turned on "Game Boost" & "A-XMP" which overclocked my CPU & RAM. After that when I started a game it ran only for about 10 seconds and my system crashed and restarted. I quickly opened bios again and turned off "Game Boost" & "A-XMP". Now when I run any game my system runs only for around 20 mintus and then my system crashes. Can anyone help me with this? Will clearing cmos will fix the issue?

My PC specs:
CPU : AMD Ryzen 5 3600
GPU : MSI GTX 1660 Ti
Motherboard : MSI B450 Tomahawk Max
RAM : 16 GB DDR4 3000Mhz (2 sticks 8 GB each)


I recommend that you clear CMOS like this:
  • Unplug the PC (PSU).
  • Then press the Power Button for at least 30 seconds.
(the on board ROG LEDs will sometimes flash after 20-30 seconds to show that all power has been drained from the board).
- Use a flat headed screwdriver to short the CLR CMOS (JBAT1) Jumper (Touch both jumper pins with the screwdriver) for at least 15 seconds.
JBAT1 Jumper location is shown on page 37 of your manual:
  • Plug the PC back in.
  • Press the Power Button to turn the PC on.
  • Repeatedly tap the DEL key
  • A screen should come up telling you to press the F1 key, do that.
  • Set the Optimized Default settings and Press OK (this is on the EXIT tab)
  • Save and exit the BIOS.
  • Tap the DEL key again to enter the BIOS and change any settings you want changed then save and exit again.

Then answer Lutfij questions.
