Hi all,

I am currently encountering random restarts with my pc, sometimes it will BSOD whilst gaming, other times the screen will just corrupt and restart instantly when I am in windows doing nothing stressful i.e. browsing.

I am running the following:

AMD 965 BE at 3.8GHz
4GB 1600 MHz RAM
ATI 5770 1Gb at 950/1300
2 x HDD's
1 x DVD Drive
3 X 120MM Fans
Running Win 7 64bit

My overclocks were 100% stable for a long while before this problem started occuring, I have also tried testing with no overclock and the problem is still happening. Temps are not a problem either, I have a Scythe Mugen cooler and CPU doesn't go above 52.

I am running all of the above on a Hiper Type R 480w power supply, which I have had for about 6 years - is it possible this is the cause of my problems? If so, what PSU can you recommend for under £80?

I will be looking to crossfire the 5770 eventually too.

Many thanks for your help.

Hi, I've copied this from another post i did earlier:

I would check your memory first using the Memtest86+ to verify your memory is functioning correctly or you could just try testing your system with just one stick of RAM (assuming you are using more thasn one stick) trying different slots and so forth.

If the RAM fails in on slot but not another, then it's either a faulty Slot (mobo) or memory controller. If the same RAM fails in both slots, but the other stick is fine, then you have found a faulty stick of RAM.. You see whee I'm going here yeah?

Next, check your PSU. You can follow my guide here

Next HDD, run a CHKDSK /r from a command line - CHKDSK checks disk volumes for problems and attempts to repair any sectors and/or system files that it finds

Lastly, check the manufacturer of your HDD and download the Disk Diagnostic software from the manufacturers website. All of the top manufacturers have one. These are normally bootable CDS. Run a disk scan to verify your HDD.

Once you've eliminated the above, you can start pointing at the motherboard.
