Random PC Crashes

Bonglord · Apr 10, 2014

So I have just installed my new motherboard and PC case and I am certain that everything is connected correctly. All of my drivers are installed but my games will not work (black screen) and when i refresh windows experience index my PC goes off without warning. I also can run a simple youtube video easily and I once got a game to start up but my PC again crashed. Help would be appreciated.

Thanks!

SPECS:
MSI GTX 670
MSI 970A-G43
8GB RAM
1TB HDD
650W PSU
AMD FX-8350

Because you use the fx8350 with MSI 970 MB, it maybe the same problem like the link. http://www.overclockers.com/forums/showthread.php?t=733680

So if this is the reason (sorry I do not fully understand this) then there is a problem with voltage levels to the CPU? And there is no fix for this? Or do I need to update BIOS?

Because the MB has lower power phase 4+1 ( VRM) that is for the cpu, also there is not heatsink on the VRM section. When you install the fx8 series cpu, they try very hard to power the CPU and will produce more heat that cause MB overheat then you know the PC will shutdown. Also we know MSI is not the good MB for the fx8 series cpu at least for now on. You can google it you will see a lot problem for the MSI MB with AMD CPU. So if you add the small fans on the VRM section like in the link to cooler it down, it will help. Otherwise you need the return the MSI MB and get the ASUS M5A97 (R2.0) or GIGABYTE GA-970A-UD3P if you want keep the fx8350.

There is an even bigger problem now. I reinstalled my old motherboard and the same thing is happening except I CAN run games (after a few attempts and it takes longer but my PC will eventually turn off without warning. I also had bought a new case with more fans and LED's which will obviously draw more power. What can I do? Go back to my old case aswell?

What is your old MB? You need the CPU cooler and also small fans to cooler down the CPU and the VRM section, where is the 5 small square shaped objects in the left hand side of the cpu socket.

I think you are better to return the MSI 970A-G43 MB.

My old one is the 78LMT-USB3 http://www.scan.co.uk/products/gigabyte-ga-78lmt-usb3-amd-760g-am3plus-ddr3-sata-ii-3gb-s-raid-pcie-20-(x16)-d-sub-dvi-d-hdmi-matx

I also noticed yet another problem. Random spikes in the power of my PSU while playing games, it goes up to 98%!!!

(I'm not sure which square objects your referring to but it all worked fine before)

That one is same, it also has only 4+1. I add other link you can see the note: MSI has confirmed that 8-cores exceed the safe limits of this board (970A-G46). https://spreadsheets.google.com/spreadsheet/pub?key=0AgN1D79Joo7tdE9xMUFlMEVWeFhuckJEVF9aMmtpUFE&gid=0

Look like you have the PSU problem too, usually we will buy the good PSU, here is the psu tier list. http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html
