    Alright, here's what happened. I noticed my pc was abnormally loud so I unhooked it to take some compressed air and blow out the dust from inside. After I was done, I reconnected everything, hit the power, and nothing. I was confused, unhooked everything, and tried the power outlet alone. It turned on. relieved, I unhooked it, put the case back on, and put everything together, and no power again. But, the weird thing is, while plugged in, the ram and motherboard LEDs are on.
    I am not good with hardware. I'm good with software, I need some help, as I'm furious and need this computer for work.

    Sounds like a power supply issue. Does the fan on the power supply come on? If it doesn't run the supply will heat up quickly and you sometimes get some power to the motherboard in places, sometimes not.

    Unplug the machine from the source of power, press the power on button for 20-30 seconds to discharge the capacitors then check these items.

    Is the +12v auxiliary power connector for the processor plugged in? If not, plug it in.

    Is the cooler fan plugged in to the CPU header on the motherboard? If not, plug it in.

    Check the front panel connector and make sure it is fully plugged in.

    If the above items are all plugged in, proceed as follows with the power disconnected and the capacitors discharged.

    Remove the memory and any add-in cards. Blow out the slots with compressed air. With a soft cloth dampened with isoproply alcohol "gently" wipe the gold contacts on each stick of memory and any add-in cards and reinstall them.

    After the above items are cleaned and reinstalled, plug the machine back into the source of power and see if it will start up and boot.

    If the machine still does not start look at the northbridge heatsink and you should have either one or two wires running across the heatsink that connect to "eyelets" on the motherboard. Are any of the "eyelets" missing or pulled loose from the motherboard?

    Before trying the in-depth steps, I let my capacitors discharge for a night, I leave my computer on constantly, so I gave it more than a break. I tried it this morning, and it seems to be working fine. After the blowout it is SO quiet. oh man. But I heard from my dad that the next time I may do this, I may not be so fortunate.

    So for now, my problem is solved, and I thank you guys. It clearly shows that I need to update this thing, and I actually would like to ask for your guys opinion! I'm considering upgrading as much as I can with this thing, definitely including the power supply.

    Basically what I want to do, and see if you guys can recommend me anything: (I've had nothing but great from this forum, so why not?)
    I have a micro-tower, and want to upgrade to a normal-sized one. I'm going from 32 to 64bit, going up to at least 8GB of RAM, I am going to aim for a quad-core processor, (a new disk drive, but that doesn't really matter too much :p), bigger HDDs (500+ GB), and that's really what I want to upgrade. I have a good graphics card, so I don't need another. If you guys can recommend builds or parts or websites (I prefer newegg), that'd be great! I consider this solved as of now. Thanks for your help.

    EDIT: Just realized I had my old specs on here from '07! Updated specs.
