Windows XP random log off issue

[gopher_yarrowzoo]

My PC has suddenly started to log me off for no reason, it just goes back to the login box which is obviously annoying IF i'm doing stuff as I run project if / when I want and not as services and obviously IF I'm downloading then that screws the download up..
Any thoughts only recently started, think it's profile related I've not got SP 3 in so it's not that.

gopher_yarrowzoo does your Computer reboot or just log you out as a user
Both can lead to the same place and hard to pin down unless you see it happen
If you have a 3.5 floppy put a non system disk so your PC will Hold at the boot
I have had Power supply's that made this happen as well as CPUs with burned out heat grease Or even the Fuss of death that can clog a heat sink

[gopher_yarrowzoo]

It's going to the login prompt not fully reboot thus the "warm" reboot i.e windows doesn't stop running.

If it happens at work, does that mean you can go home? :hifi:

Oh yeah, and Home or Pro? 32-bit or 64?

[gopher_yarrowzoo]

It's XP Pro 32-bit, it is on a AMD 3200+.
Now here's the wierd thing it's stopped doing it now!

may you have hibernate checked in the power options???

i know ive done this on a fresh install many times and

forgot to uncheck the disk shut off and computer hibernate

options have to set them to NEVER if its a cruncher

[IronBits]

Vista Power Options: Peformance
Never Hibernate ... never sleep...
XP: power always on, turn off monitor in ~10 minutes... ;)

[gopher_yarrowzoo]

Yeah no hibernate on this PC, it does it now and then, no idea why can't be a bad bit of memory as I've really loaded up the PC and no crash then it just does it totally random - could be temp, could be something else no idea :(... Maybe a fluffed dll somewhere but I don't got XP with SP2 slipstreamed on to it anywhere.

check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and make sure Userinit value is listed. Data field should be c:\windows\system32\userinit.exe. If that value isn't there and you need to create it, use String Value when you create it.

[Death]

check system log in "manage computer". win should write down what it doing.

[gopher_yarrowzoo]

This has been resolved basically. Think combination of too much peek power draw on 12v line, there was only 20A available but I'm suspecting a lot less than that swapped out PSU from another machine which I'll get up an running again as soon as well erm I can source a decent PSU for it, dust and plenty of it no idea where it all comes from computer attracts it I think and fairly tight enclosed space with poor ventilation and you have disaster..
I've replaced the PSU, removed a load of the dust, closed it up once more since I did have it open to aid ventilation in the enclosed space it was in,and it seems to be much happier now, with only the very minor randomness which I suspect is programs exiting badly and XP borking and rebooting the PC, so damn annoying but still it works! 99.9999% of the time.
