I've just assembled a computer with the following HW config: Athlon 1,2Ghz 512MB Ram (SDR, 133Mhz) MSI 7k Turbo 40GB Hard drive All in wonder Radeon SB live player 5.1 Tekram SCSI 390 II DSL modem Printer The HW is working propoerly and I made oll of it working under Win98SE with the appropriate IRQ's and drivers. Win 98se works initially. Then I start installing my SW on it. One, two, three installations.. Windows shuts down during reboot and tells me that some registry entries shall be repaired. Sometimes it gets lost in the registry repair loop. Other times Windows explorer shuts down and indicates paging errors. At the Explorer Window level as well as when I try to start programms from the start menu. After required installation reboots I get protection errors and find out, that .vxd files have dissapeared from my ..\system\-directory (latest configmg.vxd). I repeatedly reformatted my HD and each time started from scratch. For my Hard drive Biso, Dos and Windows indicate allways less (around 39GB) than 40GB, which are specified in the HD specifications. These problems occur either one by one or in combination. Does anybody could provide help on what I have to do to get Win 98SE running stable on my computer? Thank you very much
