Hello, I can't clean install Windows Me or 98se, and hope you may have some suggestions. I have a Gigabyte GA-5SMM motherboard, BIOS Award 4.51PG, AMD K6-2 100/400 MHz, 1 64MB PC100 DIMM, WD AC8400R 8GB hard disk C:, and Quantum Fireball CR4.3A 4GB hard disk drive D:. During POST, I disabled quick boot, and the single 64MB PC100 DIMM shows ok on all three passes of the memory test. I used a DOS 7.1 (FAT32) boot disk and formatted drive C. I included /TESTMEM:ON for HIMEM.SYS in CONFIG.SYS, and no errors appear. Everthing booted up fine, and I inserted the WinMe CD in drive F. Setup started ok, but soon I got error: SUWIN caused a GPF in module COMCTL31.DLL at 0003:0E49. Then I re-formatted drive C, and inserted the Win98SE CD in drive F. I created C:\WINDOWS\OPTIONS\CABS and copied F:\WIN98 to it. Setup started ok, but then got error: Fatal exception 0D at 05A4:00000218. I searched the Microsoft Knowledge Base, www.windowstrouble.com, www.fixwindows.com, and www.nospin.com for "SUWIN" and "fatal exception 0D" but found nothing relevant. Any suggestions what to try next? Thanks, Jeff PCBUILD maintains hundreds of useful files for download visit our download web page at: http://freepctech.com/downloads.shtml
