Computer SHUTS DOWN automatically

[smshinde]

Dear All,
I am facing a strange problem with my PC.
Just assembled it two days ago. The configuration being P4 3.0 GHz, 512 MB RAM, 80 GB SATA HDD, Gigabyte motherboard having Intel 865 chipset, Mercury ATX cabinet etc.
My friend, who assembled it, has installed Windows XP and few softwares in it.
Now when i brought it to my home it is not running properly.

It starts and shows memory count, bios name, detects DVD writer ( do not detect hard disk but this may be a hardware issue) and continues operations, but after 2 to 3 minutes it GOT SHUTDOWN AUTOMATICALLY.

As it detects DVD writer so i tried running a bootable disk (Sun Java Desktop system), but after booting from DVD it runs for about 3 minutes and the GOT SHUTDOWN AUTOMATICALLY.

I tried other operations like running BIOS SETUP, but the same thing happens, it runs for 2-3 minutes and then shutdown automatically.

This 2-3 minutes duration of operation is after COLD BOOT but if i hot boot it after shutdown it do not work for even 2 minutes, shows Memory and bios info and then shuts down automatically.

What may be the problem? Is this a power related problem? I checked earthing with the help of electrician, and it is OK.

Is this the problem related to motherboard of processor?

Another thing that i noted is it is showing the processor as P4 2.4 GHz, but i purchased it as 3.0 GHz. Sometimes it shows it as 3 GHz, but sometimes it shows it as 2.4 Ghz?

Please help me ASAP.
Thanks in advance.

Hi there and welcome to the HWF

CPU- purhaps he (your friend) didnt set the correct settings in the bios? (I have an AMD barton 2500+ that always registers as a 1900 or somthing, i have to manually set the multiplier)

As for the shutting down it could possibly be a heat issue, if your friend didnt install the heatsink/thermal compound correctly it could be reaching the max temp and rebooting, go into your bios after you start your computer (F2 or sometimes DEL just after the post starts) and see if there is a temprature monitor you can look at, I'm an AMD man myself but whilst in the bios your CPU temp shouldnt be going above 40ish I'd say.

As for the Hard Disk, do you feel confident enough to take the side off of your computer and check that the sata cable hasnt come loose? That would be my first port of call.
