Computer shuts down automatically

Specs: Windows XP
Hi guys,

First i have to apologize about my English, though its not my language. i'll try my best to tell the problem im having.

since last month my computer began to freeze while im working. I had to restart the pc everytime. After every restart i could use it for next few hours.
But later on, it happened more offen. even after few minutes when i restart the computer.Next thing i came across since last two weeks is, my computer began to shuts off automatically. sometimes after been freezed, sometimes without any notice. its just gone.

First I thought its my HDD or VGA or Power unit. So i Disconnect each of those including RAMs & ROMs.

I just left Motherboard,CPU, Power unit.
Then i switched on the computer bui I STILL HAD THE PROBLEM.
I tried this fer times. sometimes it came upto bios menu.
but sometimse it didnt even come to bios menu.
Just shuts down after fer seconds.
So i wanted to know whether the problem is with the Powersupply. so i added another PSU and checked. Even this time same thing happened.

So now there are only two thing left
Motherboard, Processor

I removed the processor from board & i switched on the computer. This time Computer didn't shuts down. I waited for 15 minutes. Nothing happened.

So i thought problem is with the processor.

I wanted to claim warranty for this. but when i gave the processor to check. In thier computer processor worked just fine. nothing happened. I had to turn back empty handed.

This is driving me crazy. Please help me!!!!!! Please!!!!!!

(Note: I dnt know whether this is important or not...
But just for ur consideration i think i have to tell u this)

Im using a dongle since last week for high speend internet. i remember first time when the computer freezed i was connected to the internet. Before that i had no problems at all with my computer.

Well when you put the CPU back in your motherboard did you clean off the old thermal compound and apply an appropriate small amount of new thermal grease between CPU and heatsink? How is your heatsink fan behaving? Is it running when you try to boot?

First of all the computer can't run without the processor installed so your test there proves nothing.

Your problem sounds like overheating of the processor. Either the heat sink and fan are clogged up with dust/dirt or the fan is not spinning fast enough. Now that you removed the CPU did you apply new thermal paste according to instructions for your CPU?

You didn't supply any specifications for your computer. That makes it more difficult to help. How old is the computer?

Have you since removed the dongle for high speed internet and tried without?

Don't even turn on the computer until you have re-installed the CPU (processor) correctly. You can burn it out completely if running it without proper cooling. New thermal paste must be properly applied after thoroughly cleaning off the old stuff.

First i have to thank you all for replying me. i really appreciate it.

I'll try to answer all your questions in the best way i can.

First let me tell u my system specifications:
Asus P5s-MX SE motherboard
Intel Core 2 Duo E4500 processor
2*1GB DDR2 667 ram cards
XFX 9600GT 512MB VGA
500W PSU


For Richard59:

I guess i made a mistake. when i tooke the cpu out of the motherboard i cleand the old thermal compund. but i didn't apply anything new when i put it back.
Secondly i had no time to monitor CPU fan speed because at the moment computer shuts down within seconds. but i remember CPU temperature aroud 45C-47C before it shuts down.

For OtheHill :

Im sorry, i really had no idea that i have to aplly thermal paste before i put it back.

And about my hardware,
well... I bought my motherboard 2 years back.
CPU 2 years back, VGA only 8 months, RAMs 2 years back, But the HDD is 9 years old.....and its IDE.

I tried with & without the dongle few times. But nothing changed.

For Kuwese :

I checked the CPU temperature. its 45C to 47C before shuts down.

So do u guys suggest this is because of the overheat or something?

Thanks guys...

Do you know what LOL means? It means Laugh Out Loud. I was kidding you.

If you re-read the original statement I said "Better than many here that speak it (English) as their first or only language".

Evidently English is NOT your first or only language so the comment was NOT aimed at you. While we are on the subject, I haven't had trouble understanding your posts.
