After doing a clean install of win98 B my computer locks up at the splash screen. Some times ctl-alt-del will re boot it and sometimes not. It will go into the safe mode, I can find no problems. I have done these,,,,SFC-Reg chk-scan dsk- no probs in divice mgr. The sys is a IBM clone, 200 Pen 64 meg mem. I have all cards but video card removed. I have swaped out memory.After the installing win98 I installed Norton 2000 & Office 97. It worked all day with no problems. When I turned it on today I locked up at the win 98 screen. All help appreciated.
