I've got a Packard Bell that started turning itself off and on again, at random intervals but repedadly. My first (and most hopeful) thought was PSU. I replaced and it worked for a little while but the the problem 'started up' again (no pun intended).

I started pulling bits out till I was left with: motherboard, processor & ram (tried two different sticks one at a time.. left none in and it just gives out one contiunous bleep). Still got the same problem. Surely cant be a hd or virus issue then. And that leaves the only three bits of hardware right?

So I by new motherboard and processor bundle that came with new ram (all three bits it could possibly be?) replaced. Put it all in current case, with new power supply. Turn on for a bit and it works for a while.

I Start plugging things back in one at a time try it for a bit turn off and stick something else in; gfx card, sit around in bios, seems ok for a bit,plug in cd drive, sit around in bios for a bit, then hard drive. I go into windows and attempt to start installing new drivers, plug network cable back in (into new motherboard onbord netowrk port) in-case it needs updates, and after a while it turns off again.

I pull out hd, sit around in bios and it turns off again. Can't be the case could it?

I am thoughrouly confused!

As I suggested, power switch to mobo faulty I think. You can 'short' the connection on the mobo to re-set or switch off.

Now you have two PCs see if you can search for a new front panel, complete with power switch. If you can, test it, and sell on Ebay without an OS. At least you might be able to recoup some of your costs.

I have an old on/off switch (in my junk box), if you want it to try- i'll dig it out for you

Have you actually phyically checked the motherboard where the swich plugs in, in case you have a dodgy wire or loose connection? (unplug check and plug in again.)

im thinking maybe replace the case, if it is a faulty button. how long have had the pc and have you cleaned out the dust from the inside. I take it the fans are still working.

do you know the temperature of the motherboard are and are the fans colling it. Can you test it wi the panel of then case.

T was going to recommend speccy as it can tell the temp speccy but this may not be feasible
