Help with non-responding pc

Specs: XP Pro srv pk 2, 600Mhz
My pc randomly stops responding. It sometimes takes hours, days or weeks to occur. Sometimes after running for a short while, sometimes when Ive been running it non-stop for days, it'll stop responding.

When it happens, the mouse still moves, I can do a couple of clicks like try maximizing an app but it wont finish redrawing it, then the pc stops responding all together but the mouse can still move and turns to hourglass over an app like firefox if Ive tried to maximize it. Nothing is then clickable and the clock is frozen.

* Nothing is shown in the Event Log.
* Ram testing comes up with no errors.
* Chkdsk shows no problems with drives.
* Tested with different cpus so its not a heat problem, checked also with speedfan.


XP Pro Service Pack 2,
Dual PIII 600,
Gigabyte GA-6BXD mobo,
1GB Ram,
Nvidia GeForce4 Ti 4200,
LG DVD Writer,
4 Maxtor HDD attached via Promise ATA-133 Ultra TX2 card,
Soundblaster Audigy,
Belkin (NEC chipset) USB pci card.

Help appreciated.

Sometimes when its happened, one of the drives doesnt get detected on reboot, so I thought it might be a wiring or plug problem, so I reseated all plugs and checked connections. It'll detect it again, but the freezing still happens and the drive is detected fine on rebbot then.

If Im playing music in foobar during a freeze, it'll carry on playing in the background but wont goto the next one.

I noticed one time, the pc stopped responding when I came back to my pc which had been left for a couple of hours, the clock was correct when I returned but as soon as I moved the mouse, it then proceeded to stop responding. So what can cause it to stop responding before XP has a chance to log the error?

What happens when XP has not been used for a while and then the mouse is moved? I dont run screensaver.

Can you get into task manager to see what processes are running? That might help narrow search down

Not when its stopped responding no. When it happens it'll only allow a couple of furthur activity like clicking but it wont finish redrawing the app.

It can happen when pcs not doing anything or when Im in the middle of doing something.

Sorry if I suggest things you may have already tried.
Try resetting the screensaver to off (even though its off now)
Try checking power settings, temporarily set all power off settings to 'never'
Try disk clean up
Try cleaning browser history, etc.
Open task manager to see what's running that shouldn't be
DeFrag all drives
Update with Microsoft update and do it manually, first priority updates, then again for 'hardware' (drivers)
If nothing else helps, Try moving your primary drive temporarily to your motherboards's EIDE port to eliminate the possibility that the ATA-133 card is not the problem

When you actually get it running stable, turn off system restore temporarily for a minute and then turn it back on again to reset this new stable state as your new restore point.

In your list of specs, there is nothing about the power supply. I would also run the diagnostics from Maxtor on the hard drive

How full is your hard drive? Is it nearly full or still lots of space on it? Full hard drives can affect your computer's responsiveness slowing it down dramatically. Does your hard drive continue to tick along when the screen is locked up as you described?

@Fingers: I have done all those things except try putting the XP drive onto the mobo. I do suspect its the ata controller card driver but I dont know why it would start doing it when it had been fine for a very long time.

@kx5m2g: PSU=235W, have tried with less PCI cards to reduce current draw to no avail. Had run the Maxtor and Spinrite utilities on all drives, all clean.

@breader: Lots of space on drive. I have noticed the drive sometimes continues to light up, but I dont know which one as its one light for all.

When I have to do a hard reboot, XP doesnt do a disk scan or acknowledge it had been forcibly restarted.

Fixed by downgrading the Nvidia graphics card drivers. They have so many its a bit hit n miss which ones will work fully, as a couple wouldnt allow Hibernate to function properly.

Ones Ive tried (theres "only" another 8 to try if I have time!):

v43.45 - Works but Hibernate doesnt
v45.33 - Works (Currently using)
v71.84 - Freezes PC
v93.71 - Freezes PC

Probably some conflict with the motherboard. Hope it helps someone.

Edit: Spoke too soon. Worked fine for a month after downgrading gfx drivers, now its doing it again. Arrghhh.
