Hi, i have an old toshiba 200cds. It was working fine 'til some days ago...it powered on but nothing on screen...it was frozen...then i pulled out the 32mb memory module and the laptop working fine again but only with the 8mb onboard (not much huh). So i went for a new memory module but it was the same thing the computer powers but nohing on screen...i tried 10 different memory modules from which 2 were EDO; with those EDO PC started fine but wont recognize them (because of memory type compatibility ofcourse) but the remaining 8 were the same memory type and nothing...... is there a chance that mainboard has a failure? its curious because without memory in the slot PC works just fine no frezes or resets or any kind of problem...just that im only using 8 mb...so it seems that the main board "is working fine" right? but im really confused because if it is ok, then why i cant start with the 32mb module or any other module? i hope someone could give me some clues...thanks a lot for your time.
