    Default PC is turning off ?

    Hi, The last few days my pc has been cutting out on me, i had just done a fresh install of win 2000 and XP before this started to happen, it can happen at any time but it mostly happens when i have just stated it, then if i push the start button i get no response at all.
    However, if i take out the video card and put it back in it starts first time.
    A couple of days ago, i got a message saying " cmos error defaults loaded "
    So the i went into BIOS and noticed that the date and time was wrong, so i corrected that and have not had that message again but it still cuts out or reboots itself again.
    I took the little battery out for about an hour or so, as i thought i seen it somewere that it helps this sort of thing happening, but it made no differance at all.
    I have run all antivirus programs, Spybot,AVG, Adaware, and they say there is no problems .
    any help is very much appreciated.

    ***We need full configuration of your System.

    When PC turns off like this, It may have a power problem. Did you add anything extra on your motherboard?. How many watts is ur psu>?.

    Try putting the video card in a different slot.

    Update your bios.

    How can you put the video card in a different slot if there is only one? (I know it is possible on some PCI-E mobos.)

    One of my friends had a similar problem, his computer would turn off or restart randomly. Turns out the problem was caused by the cpu overheating All the dust in the heat sink (yes there was a lot) had severely reduced the airflow by clogging up the heat sink fins.

    Check the bios to see what kind of temprature reading you're getting

    Thanks everyone that replied,
    Forgive my lack of pc knowledge, " full configuration " i am guessing that you mean the pc spec's ? if it is, pent 4 / 3.0 mhz, gigabyte mobo GA-8IPE 1000 PRO 2 [-W], 2X 512 mb memory, [excact matching], Zalmans cooler, psu which is only 4 weeks old, can't remember the name of it, but it has XP550 on the side of it, 1 lite-on dvd recorder & 1 pioneer dvd as well.
    running dual OS's - win 2000 & xp sp2 and installed in that order.

    CPU heat range form 25 C - 44 C max, mobo sits on 26 C , just fitted another heatsink fan for it, exhaust fan as well, " query " - after i fitted the heatsink fan, i did check the /mobo manual after and i didn't hook the connection up to the one its suppose to near the cpu, would that cause this problem ? thought it should be ok because of the good heat range of the cpu.
    I have experienced shoty PSU's previuosly , were after flicking the psu switch on and off repeatly, the psu would startup, but in this case it does not do anything, it only reacts when i take out the video card and put it straight back in it starts every time.
    I have never updated the BIOS before or nor have i updated the video bios, this is a dual BIOS, so i'll have to work that out and unfortunatly i have to nick off for most of the day, but i will get back to you as soon a poss'.
    thanks very much.
