I've install the SP on my computer. I've checked the graphic interface and extra tweaks (requires 64MB). I have 160 RAM. succesfull. please reboot. system won't start up. shows "an application performed a fatal exception" etc. same with safe-mode. restored the last succesfull registry. now I get the older desktop color (win98, not 2K), but with the same error. tried not to process autoexec etc. no good. command prompt won't let me access to the CD. startup disk lets me access CD, but setup comes up with an error about requiring max. file size (do I need to edit the system.ini ?), which wasn't there before. How the hell do I get my machine to work???!?? michal.
