Here are the symptoms:

1. After pushing the power button the computer start to "rev" up and then stops. This continues. Starting and stopping... Sometimes it continues to "rev" but....
2. There are no lights when booting that show up on the keyboard and the computer does not boot Windows XP. There is nothing that shows on the monitor.
3. All that happens: Fans spinning.
4. No beeps from the computer at all.

Here's what I tried:

1. I plugged the computer into the wall outlet instead of the power strip.
2. I blew out any dust that was inside the computer.
3. I made sure all of the cables inside were secure and plugged in tight.
4. I checked the cables for my monitor.
5. I prayed.

Here are my specs for my computer which I assemoled myself a little over a year ago (all parts bought from newegg).

hmmm could be a few things u need to narrow it down: first id try cutting the system to a bare minimum, in your case taking out any PCI cards and 1 stick of ram, also you can try unpluggin the hard drive as you dont need it to get to the bios

if it doesnt work try the other stick in a differnt socket

i doubt its the GPU (grpahics card) as when mines not connected corretly my PC beebs like mad at me.

its also unlikely to be the HD (hard drive) as you dont need a HD to get to the Bios, if the hard drive was faulty it would go wrong after the POST

IMO its the CPU, motherboard or PSU

most common is the PSU, chck to see if the Motherboard LED is lit up, when there is power going to the PSU from the wall and when the back switch on the PSU is set to on, the switch looks like [0 I]

if its not on its the PSU, but u prolly wont be that lucky

its hard to test if its the CPU unless u have a spare, and the same goes for the motherboard

if you think its the PSU u can try another one from anyother PC u have in the house, if its only like a 350W take ur GPU out and see if you can use a the cheapo PSU and get to the bios

after that take it to a PC shop , or kick it

that would be a dying motherboard, usually caused by a dying powersupply. i work at a computer repair shop and i have seen this many times before. i would get a power supply tester before you buy a new motherboard though.

hmm almost the same setup as mine... unluckily for me, you have an intel board where i have a VIA -_-'

to me, that sounds like a classic overheating problem, the system overheats, smartcool (or something like it) kicks in and cools it down, then it overheats again. happened with my old Acer before i found out how to build computers myself, lol.

If it is my motherboard what would be one from newegg that would be comparable to the one that died on me? (see model in first post). I'd like one that isn't expensive but would be pretty much the same (they don't make the one I have right now, it's a "deactivated item").

I'll have to try to see if the mobo led is on. How would I do that exactly?

Right now it powers on and stays on (fans and bue light inside run) but my keyboard doesn't flash the 3 green lights which usually happens and nothing appears on my monitor. And no beeps... With the fans running would that mean that it's not the PSU?

Thanks for all of your responses! I just hope I can fix this since I'm a high school teacher and I really need a computer at home! Though I doubt my students would mind if I couldn't type out a test or do any research for lectures! :)

Actually I don't have a plug that goes into the led on the mobo. So I can't check if it goes on. The front of my case didn't have a plug that went to the led for some reason...

Would resetting the CMOS help potentially? Does the fact that it seemed like a "slow death" indicate that it isn't the BIOS so resetting the CMOS would be a waste of time?

I'm going to test my power supply today and see what it says.

If it's not the battery or the power supply then it has to be the motherboard correct?

If that's the case then which motherboard woul dbe one to buy (see two posts ago where I asked this question).

Thanks again.

Just a quick thing you could try. Unplug the power switch wires to the MB. And turn the system on using a screw driver touching the 2 pins that it was connected to.

Only thing this will tell you, is if the switch button is stuck or faulty.

I took out the ram and powered it up and NO BEEPS. Does this mean it's the motherboard?


Which motherboard is akin to the one that I had before?
