My problem begins when I went to replace the ram on my girlfriends computer (256 with a 512 chip), this same ram has been placed in it before with no problems. However, after trying to start the computer it would only make a clicking noise and wouldn't turn on. I checked and made sure all the wires were hooked up correctly and tried starting it up again, it turned on, but the monitor wouldn't receive any data, like it wasn't hooked up to the pc. (The video card for the computer is built into its motherboard.) I've tried different monitors, different ram, and made sure all the wiring is hooked up, but still nothing.
The next thing I tried was placing two 1gig ram chips along with my NVIDIA GeForce FX 5500 video card in her computer. After that it booted up completely normal, you saw the BIOS, Windows Start screen, ect., until right before the login screen and then it just went black. So I removed the videocard and ram I had installed from my pc and put back the original ram and went back to using her built-in videocard. However, when I tried to boot up her computer the fan comes on and everything else but I got this around 3 second long beep over and over and nothing happens.
So then I installed a different new videocard, unhooked the Floppy drive and Cd-Rom drive from the motherboard. It now booted up all the way to the windows loading screen, but as soon as that screen finishes loading everything on the monitor goes black like the monitor is entering sleep mode. Weird, but since the monitor work all the way until that point I assumed it was working, at least to a degree, so I reconnected the ribbon cables, booted it up, and again got that same blank screen with the long beep. Then after again unhooking the same wires that made it work in the first place, the beep still continues and I can no longer get ANY images on the monitor again.
So I completely dissembled the entire computer, checked all the components, opened up and dusted out the power supply, all fans, ect, then reassembled it (except for the floppy and 2 cd rom drives) making sure everything was in perfect working order. I booted it up which it did just fine, no noises or beeps or anything, but still no video coming from the new videocard or the video output on the motherboard. Any suggestions on what the problem might be? Thanks for any help.
