One Sick Puppy

Last week the FAT on my PC at home became corrupted. I "fixed" the problem w/Norton Disk Doctor. Afterwards other things started going wrong such as the registry became corrupted , Explorer kept "performing Illegal operations". Finally I decided to save what I could, reformat the hard drive and reload Windows 98. I spent several hours yesterday trying to get Windows 98 to install correctly. I started from scratch three times even going as far as running FDISK to delete and create a new primary DOS partition. Windows 98 installs to the point where Windows starts up and is creating a hardware driver database. Then is starts complaining about corrupted CAB files. The one time I got it past this point Explorer "performed an illegal operation". I am begining to think that there is some sort of hardware problem with my PC perhaps the HDD even though all of the tests I have run on it turn up nothing. Should I use my PC for a boat anchor or what?

Thanks in advance,
Glen...

The symptoms you describe are common with a hardware problem.  My first suspicion would be a failing hard disk.  Second would be a bad RAM.

If I had to hang my hat on one answer, it would be the hard drive.  They are a 100x more likely to go bad than a RAM chip.

BTW, I forgot to ask.  Are you overclocking either the CPU or the memory bus?  If so, then that swings the balance back to the RAM.  Revert back to non-overclocked settings and verify things.

To answer your question, I am not positive but I'd say yes to over clocking but I have not changed any of the CMOS settings.

One thing thing that I tried last night was to swap sockects with the ram modules (I have 2 - 32MB 168pin mods) after doing so the PC would not boot at all. Hmmmm.

Again, revert back to non-overclocked mode and see if the problem goes away.  This is always the first thing to check when you start having trouble.  While overclocking works well most of the time, the fact is you are running parts beyond their rated capabilities.  Sometimes it works, sometimes it doesn't, sometimes it works for a while.  Electronic components _DO_ degrade over time.

Sometimes you need to load DOS Eide drivers ( chipset SIS,VIA,ALI) in your config.sys to install WIn9X ...

You must modify your boot disk ; insert in your config.sys a line  with "device a:\udmsys.sys" or something like that.
You must copy driver "udmsys.sys" (for example) on your boot disk.

Overclock : Agree with jhance ...

Thanks for the info but as it turns out physical memory was the culprit. One of the 2 32MB DIMMS was bad. I have successfully installed Win98 since removing the bad RAM.

Thanks once again for you comments.
