Hiya,

Hmm, where to start.

About 3 months ago, my system started freezing after the screen saver kicked in. I'd have nothing but a blank screen (my option for screen saver) and the only option I had was a hard reset. I've have this system for 4 years, and has been pretty much bulletproof before this problem started. I didn't think much about having to reset, just thought that it was odd. Two days passed, computer was on 24/7, and I had to hard reset again with a freeze at a blank screen. Then, it started freezing while working at the desktop, no BSOD's no warning, just a hard lockup.

There are no events logged in the event viewer. Power saving is set to presentation (don't turn anything off). I thought that maybe it was my RAM playing up, as about 6 months before the problem started, I added another 1gig of Ram. I have since tested the Ram, removed it, reseated, swapped etc.. the system still freezes. I have purchased another PSU, this did not help. I upgraded the Motherboard BIOS, once again, no avail. I reformatted my C partition, and did a clean install of XP Pro. Using the old drivers that were supplied at the time of purchase. Still freezing. Now, to make things even more interesting. The system _will not_ freeze if I'm playing a game. I play Eve Online, and if I leave this running, the system will stay up. If I alt tab back to the desktop and start moving / copying files, there's a big chance that the system will freeze.

Thinking heat was another factor, I pulled the system apart and gave it a good cleaning. Heat doesn't seem to be an issue, as I have the side of the case off, and the room is airconditioned. I've disabled all the motherboard onboard features, ie. LAN, Audio, RAID, USB, etc.. to no avail once again, the system will still freeze. It might take 20 seconds or as long as 30 minutes before it does, but it'll still do it.

Oh, I also replaced the nVidia 7800 with an ATI 9800 XT, and yes, you guessed it, the system will still freeze. I've run memtest, mbm5, etc.. I've even added brand new sata hard drives (I needed more storage anyway) and done a clean install of XP Pro. So I highly doubt it's a bootsector virus or anything along those lines.

System:

P4 3.00e Prescott (50-55 temp reported via Bios)
ASUS P4C800-E Deluxe Motherboard (Latest Bios Installed)
PSU Thermaletake Butterfly (480 Watts)
XFX nVidia 7800 GT (Lastest Drivers)
2gig (4x512) DDR2 PC3200 Kingston Value Ram (2xPaired)
2x 750gig Western Digital Sata Hard Drives

Everything else is on the motherboard.

Oh yes, the system will still freeze in Safe Mode.

I really tried everything I can think of, besides a motherboard / cpu replacement. I've ordered new parts for a new system I'll be building, as I can't put up with these freezes any longer. But I'd love to find out what is going on, and hopefully keep this system as a back-up.

Any ideas are welcome, once I have the new system built, I'll be able to play about a little more in trying to locate this problem.

Thanks for your time,

Regards,
Kozza

turn off pat and test

get the right iso, extract it, burn to cd with nero or imageburn

boot your computer with the cd and run memtest

Hiya DaChew,

Well I've tried to turn PAT off, but there's no option to disable it on the P4C800-E Deluxe, only options I have are Auto and Enabled. Looking through a few forus, I found out that there's 2 places in the bios that if I set to Auto apparently disables PAT. After trying this, and a few other settings, the system would lockup a lot quicker, sometimes not even loading XP at all. So... Seems that it is this PAT. I'm assuming the only way to fix this would be manual overclocking, though, this is one thing that I'm not that experianced with. Or, if I wanted to keep the 2gig Ram without overclocking, purcase 2x1gig sticks?

Though, the system would still lockup with only 2x512 sticks. Also strange that it took about 3 months for this problem to pop up.. damn, have to love computers. lol

Regards,
Kozza

turning off pat makes a computer more stable not less?

Hiya DaChew,

Yes. Seems to be the way.. because, apparently, with both set to Auto, that turns off PAT. But I can't even get a boot up with them both set to Auto. Locks up at the Windows XP loading screen. I'm going to play around with the overclocking, and see if I can get some sort of stability.

Kozza

experienced builders and even overclockers had to "play" around a lot with those families of boards, never could get the one I fooled with to quit trying to boot to a usb external drive if it was hooked up

good luck
