after I got my new pc, I autoclaved my old one and gave it to pops to be donated. The machine had an extra 40 gig HD and a stick of ram that I put in another system. now, when trying to install windows on the new machine, it won't load. here's the email he sent. Clyde, The first time I tried to install and run Win 98 it gave me an error of: Windows\system\vmm32.vxd missing or unable to load. This is with your Win 98 CD. Also each time I tried again it said both C and D drives were error free ( during setup). It takes forever for it to do anything, even loading the startup disk. I think it is looking for the missing hard drive?? Now when starts to load Win 98 from the hard drive it gives an error and a popup screen headed EXPLORER: This program has performed an illegal operation and will be shut down. Under DETAILS it give this message: explorer caused an invalid page fault in module "explorer.exe" : at 017f:00401f31. When this popup is closed it goes to blue screen. With Ctl/alt/del you get an end task/shut down/cancel popup and clicking shutdown will eventually shut down the PC. As I said, I think the "all ahead dead slow" is being caused by the missing hard drive. Dad if the HD is wiped, why would it be looking for the missing HD? would the boot disk he used make a difference? I had a couple of old ones in the stack of disks I gave him with the computer..... if the one he used was made under the old hardware configuration could it cause this problem? grrrr. not even the computers I used to own are working. and there was no hot water in the shower this morning.
