Hello. I was fidling around with my system and came upon the ntfs compression. So I dicided to save some space on my boot disk and compress some random big folders with the ntfs right click compression option. All was working fine I saved some space. But then I tried to reboot and I got all these strange messages like this (btw it is in dutch "Kan stuurprogramma niet laden" means cannot load driver. Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\NDProxy.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\NDProxy.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\lbrtfdc.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\Sfloppy.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\i2omgmt.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\Changer.SYS Kan stuurprogramma niet laden \SystemRoot\System32\Drivers\Cdaudio.SYS and this one: Event ID: 4609 The description for this event could not be found. It contains the following insertion string(s): d:\nt\com\com1x\src\events\tier1\eventsystemobj.cpp I searched forums for this last one and all I heard was about new drivers and I they had installed new ones.....Well I did not install new drivers or whatever I only compressed certain folders like the windows system folders. Ehh? I tried decompressing the compressed folders but that did not work either. My system just kept giving me a blue screen when I try to boot. The only way I can get on my system is by pressing f5 and entering the Boot VGA modus. So I started trying some more stuff like compressing the entire C drive with the right click on c drive compres option. After I compressed the entire disk I was able to get into my system normally no error reports whatsoever........huh? Thinking all was good and well I started decompressing my whole c drive again and all worked fine untill I wanted to reboot. Then the whole story began over again. I wonder if anybody has had this problem and knows how to solve it.( decompressing and then being able to boot up normally) WindowsXP 2600.xpsp2.030422-1633 (Service Pack 1) 3 gb ntfs c drive (now compressed) Bootstart app: From Registry : LOGITECH UTILITY From Registry : SYNTPLPR From Registry : SYNTPENH From Registry : ATIMODECHANGE From Registry : ATIPTA KERNELFAULTCHECK : updates: Windows XP Service Pack 1a : Windows XP Hotfix (SP1) Q328310 : Windows XP Hotfix (SP1) [See Q329048 for more information] : Windows XP Hotfix (SP1) Q329170 : Windows XP Hotfix (SP1) [See Q329390 for more information] : Windows XP Hotfix (SP1) [See Q329441 for more information] : Windows XP Hotfix (SP1) Q331953 : Windows XP Hotfix (SP1) Q810577 : Windows XP Hotfix (SP1) Q811493 : Windows XP Hotfix (SP1) Q811630 : Windows XP Hotfix (SP1) Q815021 : Anybody? any help is really appreciated.
