Hi guys; I looked at the first 7 threads and did 'nt find my deal so i"m just going to ask.I have win98 second ed. While downloading update driver for voodoo,system shut down.On restart i received "unable to load user exe"I restarted with boot disk and extracted win_28.cab ddeml.dll as suggested on microsoft help. Still nothing. I suspect it's a virus. Any Suggestions??
