Hi peeps,

A couple of weeks ago, I decided to shell out and build myself a nice new rig. I'm reasonably up to speed with PC's and have built several in the past, but this problem has me completely bamboozled.

First off, system specs:

Motherboard: Asus P5KC
Processor: Intel Core 2 Quad Q6600 at 2.4 Ghz
Memory: 2 Gb of Corsair RAM
Graphics Card: Asus Geforce 8800 GT
HDD: Western Digital WD5000AAKS 500Gb SATA II
DVD Drive: MSI x16
Floppy: Generic FDD
Network Adaptor: Netgear Wireless 802.11g

Initially, the system worked fine but then it started to freeze up whilst playing games. The PC becomes completely unresponsive to anything but the power button. No error messages pop up, and there is no Windows recovery message after reboot.

At first, I thought that the system may be overheating (the card is huge and I used my old case), but Speedfan says that all the temperatures are quite low. The only other symptoms are that the sound can pop and stutter occasionally without crashing, but when it does crash, the sound can be stuck in a loop, also after a crash it can hang at the Windows splash screen for a while before continuing.

As I mentioned, initially I thought it may be an overheating problem, as it mainly happened whilst playing games, but now I find that it can actually happen any time, whether I be watching TV, surfing the net, playing a game or anything. Also, it can run for quite a long time before hanging (2-3 hours) or can freeze 5 minutes after a startup when it's cold.

All my drivers are up to date, Windows is updated, AVG antispyware and antivirus are updated as is Zonealarm firewall. I run CCleaner to get rid of junk every couple of days.

Looking at device manager, there are no conflicts or missing drivers and the system passes POST just fine.

I am pretty much at the limit of my knowledge at this point, but was hoping I could get some pointers here before I cave in and take it to shop and pay for it it to be sorted.

Many thanks in advance.

Welcome to BC
Does anything show up in the Event Viewer at the time the problem happens?

You might want to check your memory. You can get a free download here:


I have seen bad RAM do just what you describe.

You didn't say whether this was XP or Vista but if it is Vista I would get another Gig or 2 of memory. Vista is a memory hog.

Good luck.

the ram is prime suspect but it may be set wrong? and still be good


use coretemp to monitor those cores, you should be in the 50's tops under prolonged load


use this to crosscheck the motherboard temps(should be in the 40's

vid card no higher than 70


for a look at how your memory is configured

No. Try not. Do... or do not. There is no try.

I know this is a shot in the dark but have you considered reinstalling the OS? I had a similar problem awhile back and reinstalling the OS fixed it. Don't know if it will help your issue or not.
