PC dies after less than 1 month

[Monkey muppet]

I built a new system fairly recently

GA-K8NF-9
A64 1.8 Winnie
2x512 value (mixed, but worked in dual) pc3200
Akasa 400w (2x12v = 29a total)

I had several BSOD's with "beginning dump of physical memory", the PC would randomly kill the explorer process and the swop file would be heavily accessed.

So I did the usuall of checking for virus, spyware, malicous ware, etc, etc and found nothing (other than a couple of tracking cookies).

I ran Memtest for 10 hrs last night and found nothing - so I then removed the floppy and did a normaly restart. I then received 1 long, continous beep code from the MB. The MB manual states this as a DRAM error.

Diagnosis is either:

1) RAM
2) MB
3) PSU voltage to the ram slots.

What should I now be checking when I get home??

Update

I ran Memtest when I got home 1 pass, rebooted, and all worked OK.

Ran superPi on all tests - all OK.

Can you guys recommend anything else to stress test this rig as I'm not convinced that all is OK

try booting with just one stick, one of each at a time. Then clear your cmos and see if it does anything.

Have you tried running with just a single DIMM at a time?

EDIT: too late, yet again

I havn't yet - reason being, I wasn't sure if running non-dual mode would be OK for the memory controller

superpi!

My guess would be the PSU
what's the number under the RU symbol on it?

Superpi - what will this check??

What is the RU symbol and what number are you after???

 

[ribbon13]

SuperPi calculates digits of pi. If you have bad ram you will find out in a hurry.

The RU symbol on your PSU. The number under will be it's UL file.

try one dimm, dual channel set ups can work in single channle

OK - very strange:

I got home and ran memtest for one pass and the MB was giving me the single long beep, then restarted in safe mode.

After the restart I didn't get the bleep code. Windows will now boot with no problems.

I have no idea what has just happened

I still don't know what figures you are after on the PSU

+3.3v = 30a
+5.0v = 28a
+12v (1) = 14a
+12v (2) = 15a

Alot of the times when you get reboots, crashes, or BSOD's that seem to resolve themselves afterwards, it is a PSU issue. You may want to try using a quality PSU to see if it happens anymore. It tends to happen under a big load & when overheating, so a better PSU would resolve those issues. Good luck.

Quality PSU you say, well I have the 400w version of the one mentioned Here
