PC shutting down suddenly

    Working on a friend's COMPAQ PRESARIO SR1230 PC.Had to restore the system for him from the original disks supplied.Everything went fine.When I was finished with the restoration and installed all additional software etc , the PC was working fine for 3 days.

    Suddenly, at boot up the computer shuts down.I have opened the case and found all the fans and coolers are working.The CPU doesn't get hot at all.I have set BIOS to default settings.Still no help.

    The point of failure seems very different and unpredictable,ranging from within 10 seconds of power ON to a few minutes until I see the log in screen.After shutdown, I can't restart the PC.I have to physically unplug the power cable from the PC and wall socket and then plug it back.ONLY then does the PC start.

    I have not added any new hardware.The PC has an on board video.

    Has anyone come across such a problem?Any help appreciated

    TIA

    My folks computer is shutting down inexplicitly too. Usually after being on for some time though, and starts up almost straight away, so I'm hoping it's not a heat issue.

    No malware present, and I got them to check the smart data of the hard drives and they seem healthy.

    Which OS are you using? Is it all up-to-date with updates?

    OS is XP Home.

    But ,it doesn't even get that far.Many times,it is on the BIOS screen,the PC shuts down.Very rarely, the PC boots into XP and I come to the user login screen.

    TIA

    Random shutdowns could be - PSU, virus(?), overheating - to name a few.

    Open the case and check for dust bunnies. Heat is the number one cause of random shutdowns.

    OP, yours sounds like a misinstalled driver. Check your device manager for exclamation marks or crosses

    Faulty PSU connection

    I'd double check that first....otherwise you could try a hundred different things before you end up checking it.
    I had this before, and took the computer apart twice..literally...and buillt it from scratch..and kept getting the errors.
    Finally narrowed it down to the PSU, got a new one for 50 quid. Sorted

    You could do well to reseat the memory too etc.

    Hope goes well for ye

    On proper reading of your post - have you tried safe mode? Sounds like a driver/windows issue as previously mentioned
