Possible Power Supply Problem

adt_clone · 10-03-2007, 10:50 PM

My computer was running fine until a couple of weeks ago, when it completely wouldn't work. At the moment I am on an older computer until I'm able to fix the other one.

In the leadup before the breakdown it was doing strange things. For example, when I turned it on in the morning, it would turn straight off. Second time, it would run for around 10 seconds then turn off. Third time it would load up XP then turn off, and lastly it would run normally. This process happened at least 4 times before the breakdown.

Now whenever I turn my computer on, it runs though nothing appears on the screen, no error messages/beeps. I investigated this, and I believe I have brought it down to the power supply. When I removed it and turned it sideways, I could hear many parts moving inside.

I tried installing a previous power supply with lower wattage, although it did the same thing. This power supply could have been faulty. I also tried a 220W supply, and it just wouldn't turn on at all.

I am going to be purchasing a new power supply, although before I do, I would like to know if there would be any other cause for this other then the power supply. This will save me a lot of time, thanks. :D

What is your system specs and the psu that bit the dust?

Uhh, this is what I believe:

512 DDR RAM
Radeon 128/256mb RAM Video Card
2.6mhz Intel Pentium 4
I believe 440W power supply, somewhere around there.

Thanks. Please ask if you need anymore specs.

with the side off, can you see the cpu fan spin when you first turn it on?

Both the CPU and the System Fan spin when the computer is turned on. Also, the floppy drive is powered and it's possible to open up the CD Drives.

Check the video card, reseat it
Can you enter safe mode?
Its very possible the supply went bad, get a decent one if you replace it.

Oh ok, thanks. That's all I needed to know. It's just I get my parts at a computer markets that's hold once a month near me. So I wanted to zero out the problem with any other components so I didn't get home, put in the supply and realise it still didn't work. :D
