Total lockup/freezing issue on new build

Hi all,

About two months ago I bought myself an upgrade for my battered old pc. All was working well until about 2 weeks ago when suddenly I started experiencing random freezing, I'm not just talking about no mouse, I mean, full on lockup, sound on loop and unable to turn num lock on and off, bad times. It can freeze anywhere from while windows is loading to when browsing Overclockers to playing a game. Its very perculiar.

I have tried all sorts, from re-seating the RAM and CPU to updating all drivers and am thinking about clean install of windows.

I have been reading somewhere that a shabby PSU could be the problem, I have been wondering about this as mine came 'free' with my case, so it can't be owt clever.

By the way I have enough cooling, side fan blowing onto CPU then a rear case fan sucking air out.

Also Event Thing in windows shows nothing expect for when I have done a hard reset.

Anyway I'm just after some ideas as to what it could be because its driving me mad!

My specs are below:

- AMD Phenom II x4 955
- Asus M4A785TD-V EVO Mobo
- 4GB Micron DDR3 RAM
- ATI Radeon 4670
- 1x LG DVD RW
- 1x 500GB Seagate Drive (SATA)
- 1x 250GB WD Drive (SATA)
- Windows 7 x64 Ultimate

The power supply is: EZCool 500W Socket 775 ATX500 JSP??

If you need any more info please ask, I'm totally stuck.



ALSO I can run XBMC for hours watching films but if I go to play a game it simply just freezes after a few minutes of gameplay.

Haha there is another problem! I updated the bios with ASUS EZFlash and all went well until it rebooted and the screen didn't come back on. I got it replaced last week under RMA and the problem still persists with the freezing.

Therefore I don't fancy doing that again!

I did a memtest for the RAM and it seems to be fine.

All settings for RAM are on auto in bios.

RAM not clearing? How would i solve that?


Thanks for your help

the only thing that I can find is from when I have to do a hard reset. Nothing else shows. I'm currently away for the weekend but home later so any suggestions I'll try when I get in


Thanks

What app did you use for the mem testing and how many passes did you run?

Ken

I just used the built in windows one, ran it twice.

Ok, I'm back home and have some info that you might be able to make something of.

I downloaded Prime95 x64 and ran it with default settings. It froze my pc after around 1minute of use.

I then went into the bios and increased the voltage of the ram to 1.135 or something, the first increment that the motherboard is set too and my system wouldn't boot, it would simply freeze on the loading screen for windows. Set it back to auto and it booted fine.

My bets are on the ram, could anyone confirm this?
