need advice

HP desktop
P4 XP SP2
Motherboard: socket 478 (sorry thats only what i heard from the repair man)

so im getting confuse with this problem
when i came in the office, my pc its running, im sure that i shutdown it properly last night
it will not take long, and it will restart itself (properly shutdown, then start)
but later, when the restarting runs, it will not load the welcome screen it will restart again

im in the internet cafe as of now (for to log this)

we try to take out one by one from connection:
we take out first HDD (then we try to start, but still same problem)
then Floppy drive ..........(same problem)
then RAM..........(same problem)
then CD drive..........(same problem)
then we try to use another PSU but still same problem

only the proccessor and mother board is not yet check because we dont have extra (in the shop) same item

any idea which one is the problem? or where is the problem? or what is the problem?
need your kind assistance
thanks........

 

well did you try booting it to safe mode
by hitting F5

 

Safe mode is f8

srry

 

You're doing all the hard stuff first infoseeker.

See how this goes>

To start your computer by using the Last Known Good Configuration feature, follow these steps:
1. Start your computer.
2. When you see the "Please select the operating system to start" message, press the F8 key.
3. When the Windows Advanced Options menu appears, use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER.
4. If you are running other operating systems on your computer, use the ARROW keys to select Microsoft Windows XP, and then press ENTER.

 

thanks for all the reply
i try in safemode--- still same problem
Last known Good........... nothing works
i (we, together with the technician) that the problem is the switch on
there is something losing contact or what
This is really crazy, we check all the hardware install but the only problem is the smallest thing i think
But thanks all guys, im still looking for this switch cause ist not available in pc shop, i must look in electronics

 

What do you mean by shutdown properly by itself? Went through the usual procedure?

Maybe you picked up a worm?? Have you got anti virus boot disc's to try?

 

yes the usual procedure
Worm? hopefully not
Yes im using AVG ang last week im been in thourogh HJT with CHASLANG assistance (and all is been fixed)
Actually its (pc) in the shop now, and the switch is in my hand to look in the electronics shop (as of now im in the internet cafe) and its running okey (naked)
Because as in my LOG quoted, we take out first the HDD then we try to start in 2 seconds after it shutdown then follows the other hardware (listed above)

so hopefully we got the right one (switch)

By the way thanks for the reply, as soon my pc is fixed i will let you know (probably by thursday morning- phil. time)
