Have read many posts and tried what was suggested. I pulled the 2 memory modules and cleaned the contacts with an eraser. I inserted only one of the modules at a time, switching slots etc. and then powered it up each time. Once with only 1 module installed, I got the WINDOWS XP startup screen (with the moving bar below) and then the Toshiba Splash screen appeared and then the screen went blank again. Seems like the hard drive starts up and then stops. The DVD drive seems to respond with a low clicking sound. I hear a couple chirps/clicks from the hardware but no beeps whatsoever. I'm guessing bad RAM. I will try with some new RAM later when I get some. Since I did get the machine to sort of startup once, am I safe to assume the BIOS and Motherboard are okay ? Thanks in advance for any suggestions.
