I have a Dell 4100 computer with a Pentium III processor running Windows ME.
I recently put in a extra 64MB of memory and an GEFORCE MX 400/440 graphics card.
I startd the computer everying went well, downloaded a driver for the card. After installing the driver i restarted the computer and it said " updating files " ( or something similar) please wait. After 1 hour the computer was not doing anything so i restarted it. Nothing happened.
I removed the card and memory now it will restart but only ever in safe mode. Tried various things but if you try to start in normal mode it just crashes on start up.
I even reinstalled windows ME but that made no differance.
when in safe mode try uninstalling ALL graphics card drivers in your device manager. when you restart your computer it should detect your current graphics card & install the driver or prompt you for disk.
In your initial changes you most probably have damaged a linked .dll file. dll files are small multi use programmes that can be shared by more than one programm. This was probably the message that you got "updating files" As you have now reinstalled windows you will now not have any restore points.
This is why you can run in safe mode as it does not require all drivers etc
I think that you need to ID which programme is causing the problem. One way might be to do a controlled start up, removing everything at start up and then re-introducing one at a time, using MSconfig, some info here on it. click here
Also have a look in device manager and see if their is any problems flagged against any drivers. if so delete the driver and reboot.
