I was advised to remove some seemingly incorrect driver files, namely Intel's 845G/GL Chipset Drivers and their Intel Accelerator App - they seemed to mess up. I was also advised to remove my sound drivers as they should be installed after Intel's Accelerator. I went to safe mode and started uninstalling the drivers from Add/Remove Progs. When it came to my audio progs (SoundMAX) the system hung. After a LONG time, I forced a reboot. I got a C++ runtime error (I think) regarding Ikernel (in MS Installer I think) when I tried again. I think I should have been more patient, but the damage seems to have been done...... Now I can boot into safemode, but when I leave it to boot into normal mode I get a new hardware found - Intel Graphics Chipset (KCH) Driver. Then I get Microsoft's wonderful bluescreen. I notice that if I remove the drivers from Dev Mgr and reboot in safe it installs the drivers - in Driver Details all the drivers are digitally signed. After I boot normally and it bluescreens, and I check Driver Details again, I see one of the drivers is no longer digitally signed, and has a different version number.... (The problem seems to be with my Intel845G/GL display adapter drivers) After install: c:\Windows\System32\DRIVERS\ialmkchw.sys = signed, ver:6.13.01.3055. After bluescreen: ialmkchw.sys = unsigned, ver:6.14.10.3619. Most of the files are in the directory "drivers", but the problem file and 2 others (ialmnt5.sys and ialmsbw.sys) are listed as being in "DRIVERS" (capitalised) - is that normal? So can anyone shed any light on what's gone wrong, how to fix it (HP System Recovery is my LAST RESORT ONLY!) or just how to boot up without getting the bluescreen? Thanks, BL

BL, Check the end of your last post. Clark

There has to be another way - I've been told there's a file in windows (apparently in a CABS folder) that will replace every driver with the original - i.e. factory settings. I can't find what does it. Can anyone tell me? I don't trust HP's System Restore - I had problems, used it, and I had a clean system... with the same problems. Getting hold of an XP disk is difficult right now, or I'd do a full reformat. Anyone else? BL (PS System Restore will be run if I can't get it fixed within a couple of days... :()
