Last month I started suffering power loss issues.

There may have been a power surge in my neighbourhood at the time, which I hope did not cause damage to my PC.

Basicly, my machine has developed a habit of;

1) Turning itself on randomly if the power is not swithched off at the wall.

2) Turning itself off randomly,

3) My Windows shutdown menu appears randomly, which sometimes preceeds a random shutdown.

I'm not a technical genius, and I can think of three different things. Admitedly, not all of them are probably feasible.

1) The power button on the front isn't connected properly anymore. 2) The powersurge could have damaged the PSU or something on the Motherboard. 3) Overall, my machine is 4 years old and the PSU could need replacing.

Hopefully (fingers crossed) it's not going to be something that requires having to get a new machine....... le moolah is not something I'm currently flush with:(

Any help or advice would be greatly appreciated.

Try installing a program that analyzes hardware like Motherboard Monitor (freeware). There are probably others now that are more modern, MB Monitor is just one suggestion. It will track your voltages for stability and levels. You should be using a surge protector too and I'm not sure what you mean by switching the power off at the wall.

Do your household lights flicker at times? Try plugging the PC into another outlet on a different circuit in the house/apartment. The circuit you're on could be faulty. If it's an apartment you may want to have the landlord check the wiring. You could as well try plugging it in at a friend's place to see if you have the same problem.

If you've done upgrades (like a more powerful video card) and/or the PS is old it could just need replacing. Often times when a PS is bad and/or overstressed you will hear it clicking on and off.

I took your advice and tried a different plug socket (for the PC itself, no keyboard, monitor, mouse and other things), then at a friend's place. Unfortunately, the same thing was happening, so we both agreed it was the PSU. On the bright side I've been able to cannibalise my older PC, and use its PSU as a temporary stop gap until I can get a proper replacement. Thanks alot for the advice Omen:)

I had the same problem with computer turning on when i shut it off. There are several different ways of fixing this and my problem was my graphics card that was turning the computer on because it had an problem somewhere. It may be a power supply error. Run regedit and go to HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/currentversion/winlogon Here you will see alot of keys and variables. Check after "powerdownaftershutodown".. This should be "1". Try turning off your hibernate at the power supply in the control panel. This is what helped me. Go to System in the control panel. Click Advanced and then "Device manager". In here take your network card and click properties. Get to advanced and just take "none" on "Wake up capabilities" Hope that this will help EDIT: Saw that u have got your help now :P

Good advice aswell, thanks. Something I'll keep note of for the future:) Unfortunately, getting the machine to stay on for a long enough period (on the previous PSU) is highly problematic..... it turns itself on and off many times in succession before it actually gets to the logon screen now. Still, the stop gap I mentioned in my previous post should give me the chance to try your reccomendation.
