Computer switching itself on. :(

Messiah Khan · 17 Jan 2007 at 10:26

Following on from my Tagan woes thread, my computer is sort of behaving itself. It however keep switching itself back on after ive turned it off to go to bed for the night. Ive checked all the wake on LAN settings, reboot after AC failure settings etc. Anyone have any suggestions as to why it might be doing this? Im having to switch it off at the back of the PSU to keep it off.

Sticky power button ?

Nope, stripped it all down so its not even in a case now.

power surge?

Initially thought this when the computer kept switching itself off randomly, but its stopped doing that now. But I hightly doubt it, as it does it EVERY time I switch my pc off. I turn it off, then 10-20 seconds later, it boots back up again.

Yup. As I say ive stripped the whole rig to pieces and put it all back together on my desk. Theres deffinately nothing shorting the powerswitch pins on the motherboard, as I have to manually short them to get it back up and running. Oh, and thats another point.. when I want the computer back on, i can flick the PSU power switch to on, and it doesn't boot itself up. It only seems to want to do it after ive switched it off. And when I say 10-20 seconds, its as long as it takes for the fans to stop spinning etc.

ATI motherboard chipset by any chance ?

Nope. Nforce4. The motherboard is a MSI K8N Neo4 Diamond.

How's about the other wake up events!... PS2 or even USB (summut might be resting on the keyboard!!... or the mouse might be a bit flakey!!)... My board (NF8-V2) has settings in the BIOS and jumpers on the board (near the USB/PS2) to set/unset this!!..

I'll have a look at this when I get home.

Nope, not that. All wakeup events are off.

I know this really isn't helpful, but my friend has the exact same problem! He's tried everything, and he temporarily stopped it by taking his sound card out... but he needs his sound card, so that wasn't a permanent option. He just switches it off at the back after shutting down before it gets a chance to turn back on

Yeah, thats what im doing at the moment, but im getting watercooling and phase cooling soon, and want the actual rig to be behaving itself before then, as if it really falls to pieces, I don't want to have to drain the loop etc.

Well if it's not shorting.......hmmm, perhaps it's the motherboard thats had it? Only thing I can think of.

Yeah, ive come to the same conclusion tbh. Im looking at getting a DFI Lanparty SLI-DR Expert off MM to replace it. Fingers crossed thats the problem.
