Yep,It freezes up right after the first post comes up and thats as far as it will go. So I can try new memory and see if that helps? It came with 1gb(2-512mb) and I added 1gb(1-1gb) about a year ago. How much should I go get to try it? Thanks for the help and info. I just use my desktop mostly for my music and videos but I miss it. It does have a tuner and I record shows so I can watch them while Im on the treadmill. I also have some programs that only run with XP so if I replace this computer I will probably look for a used one to take its place. Any insight on that would be helpful. Need to get it going so I can get back on the treadmill, ate too much today.

remove all ram sticks and boot computer ,what happens ,if ram is the problem it should not shut down but stay on and make beeping sound !
Sound like CPU or Power supply could be over heating ,make sure all fans are free of dust !,

It seems to me that it is the motherboard, cause it doesn't go beyond the first post and it get's stuck right there. I would consider replacing the mobo if it's worth anything. Oh way a minute did you try resetting the motherboard.(cmos).

I did take out the battery. Isnt that how you reset the motherboard?

no, you need to change the jumpers, read the manual, look it up in the internet depending on the model, pin 1 and 2 is normal, pin 2 and 3 is or reset. that is resetting the cmos most of the time is j1. By the way the way to do it is to put the jumper on 2 and 3 for 20 seconds, then put back again on 1 and 2. with the power off completely, unplugged.

removing the bios[motherboard] battery will achieve the same thing

it depends on the brand of the motherboard. more efectively is the cmos jumper.
