AMD randomly restarting pc?

[kennykse1]

I am playing dayZ in windowed mode today and the pc has started just randomly restarting. No idea why. I will just be playing the game and boom. No signal on the screen then i see my BIOS startup menu.

My setup is:

Operating System
Windows 7 Professional 64-bit SP1
CPU
AMD FX-6300 41 °C
Vishera 32nm Technology
RAM
8.00GB Dual-Channel DDR3 @ 671MHz (9-9-9-24)
Motherboard
Gigabyte Technology Co., Ltd. GA-970A-DS3 (Socket M2) 26 °C
Graphics
MON-SIS289 (1440x900@60Hz)
HDTV (1360x768@60Hz)
4096MB ATI AMD Radeon R9 200 Series (Sapphire/PCPartner) 34 °C
Storage
1863GB Seagate ST2000DM 001-9YN164 SATA Disk Device (SATA) 29 °C
Optical Drives
TSSTcorp CDDVDW SH-224BB SATA CdRom Device
Audio
Realtek High Definition Audio

Recently I purchased the new CX600M power supply and has been running fine for the past two months as well as the new Sapphire card.

I have done a system memory test and everything was fine there.
Any thoughts on what this could be??

Thanks!

Try a different PSU, the CX line is crap, from what I have heard.

Any way to know for sure if it is the PSU?? I don't have the money just to buy another right now...

It may be the PSU, you can check this by underclocking it and because that uses lower power if it runs (obviously slowly) then you probably have a BAD PSU and you will want to replace it as soon as possible because when it goes BANG it has a chance of taking some components with it.

Did it do this before you overclocked? It could be a bad overclock or a bad PSU. If it is the PSU then it will have to be replaced one way or the other. Either you replace before it goes or you wait until it dies (and it will die). if you wait though you might end up replacing more than just PSU if it takes other stuff like the HDD, video card RAM with it. Either way I would set your settings back to default and see what happens.

Yeah I agree with rds1220 you should try resetting your BIOS to default settings although you could risk messing up your boot tables which means you'll need to set your hard drive as default boot peripheral again.

As far as I know i have done no overclocking?? I have never touched the BIOS settings or the overclock for anything. Can you give detailed descriptions on what to do to test something and see if that is the problem. The PSU will still be under warranty

Try running something like Prime95 which puts the CPU under 100% load, although if your PSU is bad it should reboot or could go bang, do this at your own risk but if it reboots quickly it's your PSU not giving out enough power; you can download Prime95 from here http://www.mersenne.org/download/index.php

O I thought you had said you overclocked it. In that case then it is probably the PSU. Besides dying out is it giving any BSOD?
