BobG, Horatio, Maggie:
thanks for taking the time to educate me; for sticking with me through thick and thin; after the weekend trip to chicago and returned to fix the pc as BobG suggested. thanks to Horatio for clarifying the point. i did as directed and reformatted c:\, reinstalled w2k, etc.
The machine now runs so smoothly and flawlessly--all due to your unfailing support and counsel. i am profoundly grateful to each of you. Sisyphus did roll the rock over the hill after!!
BobG, how he did you do it? He got a few people to help him!
i will put a 400 Watt. power supply at a later date.
Incidently, the problem i encountered earlier regarding the inability to get more than 16 colors, the blur screen and text, etc., all that is gone, too. i have my 256 colors and nice text.
it really works like a charm now. i was afraid that i won't be able to finish ironing out the problems before leaving on an extended trip to Tokyo, Bangkok and Malaysia! Now i can go in peace.
Am profoundly grateful to three of you. BobG, in particular, worked hard in helping me. Horatio, you are always there, to lend your expertise. Maggie, i have heeded your advice.
