Ok, I know this isn't meant to be a tech support forum, but I don't like most of those sites, so I'm throwing this out to see if there's a bigger geek than me that can help. Long story, please bear with me.
I tried to turn on my desktop after being gone for about 10 days of vacation. I heard things spin up, but nothing went out to video. The monitor was getting a signal, but nothing showed, not even the bios or self test. My computer is basically self built, a few years old. The basic specs are:
AMD XP 2500
512mb pc2700 RAM
nVidia 64mb video card
2 hard drives
onboard audio, lan
OK, so first I thought it might be the video card, so I pulled out an old motherboard and processor, put in the card, attached the psu and it fired up fine. OK, so now it seems like a motherboard or processor problem, so I bought a new mb with the same socket and just put in the old cpu...same thing happened as before, power comes on, fans spin, nothing out to video. OK, so I bought a new processor, same specs, AMD XP 2500 Socket A. Same thing happened. I tried changing psu, and even installed all the new components in a brand new case (in case there was a short or something). The only things I have not swapped out are the video card or the ram...but it I don't know why the video card would work with the old slot A motherboard and not with the motherboard it has been working in for about 2 years. Also, I know the monitor is getting a handshake from the card because it goes from 'no signal' when not plugged in to a blank screen and orange led. I'm tempted to just put it all together and bring it to the "geek squad". Any ideas??? Thanks in advance.
