**UPDATED.
ok, so i reset the CMOS and had everthing disconnected but the ram, and cpu, and put in a diffrent power supply (one i know works) and it beeped, showed up on the screen, and WORKED......but.....i turned it off again and hooked up the dvd reader/burner and hdd ( so i could put in windows xp to wipe the drive and boot) and it went back to doing nothing.**

That was the problem, i did manage to fix it though. It seems that my motherboard was makeing contact with the wall of the case....it must be shorting th mb or somthing, i put a hard plastic washer behind each screw and it seems to be working fine, thanks everyone for your help, hope this helps some other people.Before we all go chasing off into oblivion, (I've read too many computer troubleshooting stories)....

1. Is the monitor on?

2. Does the monitor work?

3. Have you checked whether or not the power supply is high enough wattage?

4. Is the monitor hooked up to the correct port? Have you tried different types of cables (If that's an option)? VGA, HDMI, etc.

5. Do you have a dedicated graphics card? If yes, is there a dedicated power plug to it (PCI-E cards, have, if I'm not mistaken, a wire)? If yes, is it plugged in to the motherboard?

6. Does the BIOS beep? Does the fan ever spin down?

I may not be the one to diagnose the problem, but I'm pretty sure that it's not a power supply problem, however the motherboard could be the culprit if it got damaged somehow.yes, the monitor is working, i was useing it earlier today. the powersupply should be powerful enough, 400 watts good? there is no graphics card, i am useing the integrated (so dont need as much power)
monitor is VGA. if you would like i could list the componets i added.
Again for the power, all i have besides the CPU(amd x2 6000+) is a DvD burner, one Hard Drive and a wireless card. the fans do not spin at top speed ( so i assume then are spinning down )
i do not hear any beeps.do the HD and DVD drive cables have notches on them to ensure correct orientation?

I had some 80-conductor cables a while back that relied on the user knowing the pink strip goes with PIN one.

remove the IDE cable from the drives and try to boot

If that fails...
re-seat everything too

If that fails, remove everything except the CPU and try to boot and see if you get beeps (you should get no RAM installed error ) unless you have no speaker plugged in

If not I would waste no time returning the board and components for a replacement.

via FoxyTunesI would check the cables going from the case to your motherboard(speaker,HDD light, reset, power, etc..). Other than that, I would check the battery on your board and all of the jumpers on the board. I would recommend reading your whole motherboard manual for all board/jumper settings. If that doesn't work, return the board. More than likely, you should have to reformat that old hard drive either.Please go Read the top post.When you swapped the PSU, did it start first time? Or did you have to restart MULTIPLE times?

Let me reason a couple things out.

1. PSU is known to work.

2. MB is unknown.
2b. MB worked once.

3. When DVD and HDD connected, MB suddenly doesn't work.

One other question: What's the wattage rating on the verified PSU?

Here's a couple things to try:

1. Disconnect the DVD and HDD. Does it work again?
1b. If yes, then try just plugging in the HDD.
If this works, I think that it may be PSU related... why or how, I'm not sure yet.

2. Try leaving your computer on for around thirty minutes, and then turning off, and after about three seconds, restart. If this works, then I think your problem might be heat/temp. related... something on the MB doesn't make contact well.

The more I think about it, the more the MB seems to be the culprit.
