436728 2006-03-08 06:21:00 I've realised that my computer has started booting itself up, at random times.

When the computer is properly shut down, after a non-specific or routine timescale, the computer will start itself up again and boot into windows.
Now i normally turn off the power supply (psu) switch when the computer is not in use lol.

I am not sure what is the source of this problem. It might be the motherboard, the switch header, or just the OS.

hopefully this is not such a big problem, as i have examined the board for any leaking capacitors and such. But i would like some advice on why this happens, after all, it could be a serious problem!

My system is as follows:

Processor- AMD Duron 1.3Ghz (morgan)
Motherboard- ECS L7VTA rev1.0
HDD-Seagate ATA V 100 barracuda 60GB
RAM- Veritech 512MB non-ECC DDR400
CHipset- Kt400 and Vt8235
GRaphics- ATI R9250L- C3H 128MB
PSU- HEC 250L (250Watt)

Btw, i have not messed around in the bios or anything,
But i have loaded optimised defaults/reset CMOS jumper.

Any ehlp would be appreciated,
Thanks all!

436729 2006-03-08 06:32:00 Well, it sounds like an option in the BIOS has been turned on by someone, somewhere.

A system can turn on if:

Its on a network/LAN and an option in the BIOS option for this may have been enabled.

Some mobos can be turned on at certain times, thru the BIOS (even tho you havent changed anything, someone else may have).

Some mobos / systems can also be turned on by pressing the keyboard, moving the mouse (like some ASUS mobos). I doubt there's anything wrong with the mobo / or capacitors. It wouldnt go at all, if they were leaking.

436730 2006-03-08 06:36:00 check bios for any startups. "wake on ring" "power on after power loss" are two comman ones (may be worded differently) the first will wake the pc when the phone rings the 2nd will turn the pc on after a power cut (or slight power glitch). tweak'e (69)
436731 2006-03-08 07:00:00 Yes, good point.
My computer isn't Lanned or anything and is not currently connected to the internet :(

I have had problems in the past when another computer of mine, restarted everytime a phone-call came in. Windows turned out to be the problem so i reinstalled it

I have checked the bios settings, and nope, "wake on ring" has been turned off.
when you load optimised defaults, wake on ring is turned off anyway.
Yeah, thanks for helping out, further information would be appreciated
thanks

436732 2006-03-08 07:04:00 did you check for any power related ones ?

i wonder if could be a PSU starting to fail (low standby voltage?) ?

436733 2006-03-08 07:15:00 nah I reckon the powersupply is all good.
HEC powersupplys are pretty trusted.

I dont think systems are meant to restart or power on themselves, espesially if its actually in "shut-down" mode.

436734 2006-03-08 07:44:00 If it loses power, does it start up when the power is back on? Greven (91)
436735 2006-03-08 19:25:00 I had EXACTLY the same problem with me ex girlfriends computer, it would turn on at the most random times, i never did find the solution and now we've split up who cares lol but i always wondered if it was some sort of virus that was doing it Jimmy D (2061)
436736 2006-03-09 00:03:00 I'd agree with previous posts, either a "wake up" setting in BIOS, or possibly a wiring fault / intermittent short. kingdragonfly (309)
436737 2006-03-11 05:09:00 okay thanks everyone,
problem was sorted after i unplugged the bloody modem phone cable :)
