For the 2. time in a short periode my winXP cant start because the the windows/system folder gets corroupt. I think the 1. time was because of a virus called Geebeewin32 or something like that. But this 2. time im pretty sure it is not a virus. I have been messing with my ram, changing the DRAM cycle setting in the bios. I have also discovered that there is a hardware error in my ram (with the help of MemTest). Can it be the RAM? My computer: AMD K6 thunderbird 1000mzh 512mb sdram pc-100 SB live Voodoo3 2 matrox hardisk (one with 2 partions) DVD and a CD burner please help me, I lose everything when this happen.

Oh, I forgot another real pain in the butt. Now I cant boot from my WinXP CD, so I am not even able to reinstall WinXP. I have allways been able to boot from the CD. ARGGHHH! Please Please Please help me!

Subject: Windows/system folder corroupt To me it means that some system files are corrupt or missing. This is ease to fix. START RUN type CMD OK after Command prompt type sfc /scannow the original XP CD must be inserted. This wil replace all missing or corrupted system files. Cheers de Peter

how do I know when my files are corrupt?

Thanks for the tip, but I still have the problem that I cant even be allowed to boot from the WinXP cd. how do you know when your files are corrupt? Well when you boot windows cant start and a error message sayes "the windows/system folder is corrupt or some files is missing"

Ok now I can boot again (it was something with the BIOS setting) but I cant use the sfc /scannow command since I cant get into windows and repair CMD funktion you can run from the WinXP CD dont have this command sfc /scannow. What to do to fix my windows?
