I read some archived messages about this computer and seems to be the power board in the computer itself was/is dodgy so that's most likely the problem and i've not enough experience to diagnose and fix the problem. 8-( looks like this computer will go with the other nonworking machines like my kyotronic85 and ps2 model 90xp.
