I just built a new system: Socket A - Soyo K7VEM Pro V1.0 Motherboard w/Duron 850Mhz Processor, PNY 256 RAM, 20 GB Western Digital HDD, etc...
I'm running Windows 2000, Office XP Pro 7 and a few other programs. Everythings working fine except for now I have this one little problem, it says (when I try to install something) there's not enough disk space. In My Computer it shows 16 gb free space. I used Fdisk to prepare the drive, creating one partition. I haven't gone into the BIOS yet to check things out in there. I ran out of time, the computers at work. Some Ideas please.

Some things to try:
-Clean out all Temp folders.
-Specify a virtual memory setting(Ex.- 100MB) instead of allowing Windows to manage VM.
-If you're installing from a CD, then disable autorun, and manually run the setup.exe file.

Thanks ski. This is a new system. I did finally get to the BIOS today and found that the access mode was set to auto detect. I changed it to LBA and now I can load programs. I guess that was the problem but I not sure why auto detect didn't work. At first the changes didn't work but when I removed a CD image (almost 700 mb) from the hard-drive then I was able to install some more programs. I also was able to reload the CD image. It's beyond me.
