(Note, everything in this has been from googling my errors over the last five days, myself, I know relatively nothing in this subject ) The background - I attempted to upgrade my Nvidia graphic card drivers following correct procedure, hit "ok" to about 20 screens with some tech jargon about "scripting" in them durning the uninstall of the drivers, after the uninstall completed, my net connection was dead as well, so no installing the new drivers. With nothing left to do (i'm new with this), I shutdown. Now, I get a blank screen after the windows XP loading screen (even in safe mode). (Advanced warnings) -it used to be a emachines, so no XP disk, I changed motherboards, so no recovery disk use. - I have a burned XP pro disk, but I cannot boot from CD, no matter how I work it in BIOS. It simply gives me "Booting from CD "Booting from CD" then throws me back into normal boot, and the blank screen. What I DO have is a windows ME startup floppy, which gets me into DOS, where I can access that good old XP pro disk, but I can't get far in setup (D:\i386\winnt.exe), as it says windows needs some 380 MB of space for the temp files, and it cannot find a drive with that much space. I know I had 13% free space on my HD last time i looked. Nothing is backed up (learned a lesson here), so I don't want to format if possible, but If there is a way to delete from DOS, i'd gladly sacifice some programs such as EQ2 which can be reinstalled, to make the space. (I noticed that in the very first paragraph when I start up, after the BIOS and graphic card info, it says I have "128mb RAM", but maybe its speaking of the card's ram, not my comp's?) Below is various information i've gathered over the last week which hopefully could be of some use... Windows XP Home Gigabyte K8 Triton Series Nforce3 motherboard AMD Athlon 64 processor 2800+ AWARD BIOS v6.00 2x 512mb Mushkin DDR Gainward Nvidia Fx5700 128mb graphics card 40? Gig hard drive I have cleared cmos, moved the ram around, switched out the video card for another, removed extra PCI cards, switched monitors. -Starting in safe mode normal freezes at \windows\system32\drivers\mup.sys. -Starting in safe mode w/networking and command prompt does the same. -Enable Boot logging gave <windows root>\system32\ntoskrnl.exe as missing or corrupt. I copied two other files in a repair operation for it, but "copy d:\i386\driver.cab c:\system32\ntoskrnl.exe /v" only returned Bad command or file name, so I was unable to finish. Oddly enough, I no longer get the error since then, it just goes through to the blank screen. -Enable VGA -boot- blank screen -LKGC -boot- blank screen -Directory Services Restore Mode - message rebooting in safe mode- drivers list, checks system, "Volume is clean. Windows has finished checking the disk". No more activity after this, does not respond to keyboard commands. -Debugging Mode - boot- blank screen CMOS Settings Halt on all, but keyboard/halt on no errors -> loads to blank screen BIOS Boot order - Floppy/HD/CD - to blank CD/HD/floppy - Boot foom CD : Boot from CD : - to blank Floppy/cd/HD, CD/CD/CD, CD/none/none, all same as above. Well.. that about sums up everything I know.. In short.. How can you reinstall/repair Windows XP home without a restore disk, and without (normal) access to your CD rom? and/or How can I safely delete some stuff in DOS to make the required 380 mbs room the XP pro disk wants to do its thing? Thank you in advance for looking at this! Feylind

"I attempted to upgrade my Nvidia graphic card drivers following correct procedure, hit "ok" to about 20 screens with some tech jargon about "scripting" in them durning the uninstall of the drivers" What exactly do you mean by "correct procedure"? All you needed to do was go to Control Panel > Add/Remove Programs, find & select nVidia Drivers from the list, then click Remove...simple as that. Here it is, direct from the nVidia website: "Before installing new drivers make sure you uninstall all NVIDIA display drivers from the Windows Control Panel. Browse to the Start Menu > Windows Control Panel > Add/Remove Programs and search for "NVIDIA Windows Display Drivers" or "NVIDIA Display Drivers" and select remove." http://www.nvidia.com/object/driver_installation_hints.html How did you do it? If you did it differently, that is probably what caused your problem, but we'd need to know exactly what you did so that we can possibly figure out how to undo it. Everything else you tried may have been unnecessary & may have even made things worse... ASUS A7N8X-X Athlon XP 1800+ 8.5 x 200MHz 1024MB PC3200 2.5-3-3-7 Asus A9550GE/TD 128MB WinME/WinXP Pro SP1
