Computer Not Booting--- Diagnosis?

Hey, I'd appreciate some tech savvy advice on what to do about my desktop computer.

1. Hardware is all compatible
2. Connections (appear to be connected)
3. Computer lights/fans turn on upon pushing power button
4. Computer does not boot up

At first I thought possibly it was my processor going bad as it was freezing after startup and fail to completely boot up, also when I was reformatting it would freeze unless I did the fast version of formatting.

I replaced the processor with one that is compatible for sure and I'm still having the same problem. It turns on all the lights and fans, but does not boot up. The monitor is connected. I've tried to rid of all small possibilities as much as possible, the computer is getting power.

The last thing I did that caused this (with old processor) was change the clock speed of the processor in bios from 300Mhz to 600Mhz, I'm not sure if this could be the cause and if it is how to change it.

Any ideas or further questions that could help diagnose my problem here?

Thank you.
 
Sounds like you could have a failing harddrive. Put your ear up next to the harddrive and see if you can hear any abnormal noises like clicking, grinding, etc. at this point that's all that comes to mind.
 
Reset the CMOS by removing the round battery for a few seconds then putting it back in. Do this when then the comp is off of course.

Also... Have you considered that it could be a graphics problem? It sounds like the comp may be booting, but just not outputting.

I haven't detected any abnormal noises.... It does the typic tck tck, then the system boots up with a beep as normal. Unless this short tck tck sounds is not usual of a computer boot up, which has been the norm with this computer I built.

I'll keep this solution in mind. Is there a way to put the hard drive in another computer temporarily to test this theory?

Actually I just put a brand new ATI Radeon 4830. The computer was doing this with my ATI Radeon 2600 Pro. I have the "beep" sounding unit (don't know the tech name for it) hooked up. It has always beeped when my computer has successfully booted.

Is there a certain way of removing the battery without damaging the motherboard? I was thinking about doing that but didn't know of a safe way of removing it.
 
Re: battery - nope, just pull it out. You'll probably need a small flathead screwdriver or something similar. Small paper clips actually work awesome!

Re: connections - are you certain everything is seated properly? Pull the video card and re-seat it. Are you getting any output to the screen? -BIOS? -error message? -anything at all? Is your monitor cable crimped at all?

'Beep sounding unit'? Case speaker? Is it one beep you hear or multiple? Long or short? Different beeps mean different things for different MoBo's
