PC boots for 4-5 seconds, then stops

Hi,

I've got a similar problem to the threads with titles like this, I press the On button on the PC, and for a few seconds it boots up, then it dies on me. I've gotten to a Laptop to post this, and I have (out-dated) specs about the PC in another one of my threads here I think - I will go fetch that soon.

I've opened the tower up and dusted down the rear and CPU fans, and re-arranged my memory sticks.

Then it booted as normal.

I then turned it off while I reinstalled all the necessary screws, plugs and cleaned up my mess, then when I tried to boot it up after all that, it again did the same thing. I'm back to square one.

Thanks to anybody who can help me.

EDIT: Some of the old specs:

CPU Type Intel Pentium 4A, 2000 MHz (5 x 400)

Motherboard Name Intel Havre D845HV (3 PCI, 1 AGP, 3 DIMM, Audio)

Motherboard Chipset Intel Brookdale i845

System Memory 128 MB (PC133 SDRAM) I now have three sticks of 256mb PC133 SDRAM installed, they have been a great investment and my total ram is 768. Hope this helps

BIOS Type AMI (04/15/02)

 

OK, I hear no beeps but the CPU fan/something inside it makes a click and everything halts.

I'm having no luck at getting it started at all now, maybe if I leave it for a longer while. What's the fast and probably expensive solution?

How would I go about checking BIOS and that stuff when the times comes? I'll try doing that on this system just for the heck of it.

 

This is funny shit.I had the exact same problem last week,
Computer shuts down at anytime ,it used to be in games ,but got worse and worse I did the exact same thing you did...Im pretty sure your cpu is overheating or your power supply is defective ,that was my problem and it now works.

 

what do you mean stops ,does it stop then shut off or stops and freezes.

Btw thats one old system how long have you had it for ,if you had for over 3 years every piece could be broken ,time for an upgrade=(

 

What did you have to do?

 

Your computer is old and can have many problems.What i did was first buy a new cpu fan and stop it from overheating.Then baught a new power supply mine was defective.

 

im not sure were i got the idea that your comp is 3 year old,sorry

 

Sounds like a power issue.. when you say you hear a 'Click' is it exactly that or is it more like a 'Clunk' ?? Check the power lead connection to HD, Unhook your Roms and try one of those power leads to the HD, just connect the HD and nothing else, like disconnect Power to Floppy/Roms as sometimes one of the connectors/leads could be faulty. If it then boots connect back one at a time what has been unpowered.
