Suddenly it happened a couple of years ago. My Tecra 8100 did not boot up. Black screens, beeps and all that. for some reason I tried to unmount one of the two memory modules. And the machine booted again. I talked to a Toshiba technician, who told me at once that he could fix it. You just resolder the memory sockets... So I let him do that. It cost me round $100 and then I had a fresh computer for round two years - and then it happened again... I adviced my son to buy a Tecra 8200 (before it all happened) and the same memory socket error happened to him. Now I have two complete Tecra 8100 + 1 motherboard, all faulty, and one Tecra 8200, also faulty. 256 MB of RAM is not very much with WinXP... Does anybody have the same experience? Or is there anyone who does not at all have the experience that two memory modules might make the Tecra not boot?
