grey screen on startup, add a device trouble!

Hi,

When I turn the power on, it logs in to a grey screen,
(doesnt load up to the desktop) and "Add a device" pops up
saying it has found a device, but doesnt say what device
it is. I am thinking it might be the graphics card or
motherboard?? (Coz it goes grey and goes into 640x480
mode). I try to put the cds in for the comp. to find the
drivers, but windows refuses to search the CD drive, the
CD drive doesnt even show on the file source list, only
the hard-drives the A:\ drive and a couple of others.


I also dont have the Windows ME disk, as a copy of it is
meant to be on the hard-disk. As for the emergency restore
floppy disk, it no longer works as I have upgraded my
computer, and the last time I used it it made things 10x
worse! (the disk didnt really recognise any of the new
hardware so gave up i guess!)

It must have happened when I moved alot of files from C:\
to another folder and also C:\WINDOWS to another folder
(as I was trying to clear my computer out abit and would
have thought all important files would belong to a
folder!) However I managed to get into DOS and put
everything back to their respective folders.

Safe mode etc doesnt work, gets to the grey screen and
nothing.

I do have the cd's for the graphics card, motherboard etc,
but because it doesnt say what device its found, and the
reason why device manger wont attempt to read anything but
the A:\ drive, there doesnt seem that there is alot I can
do in this device found screen! I can press CTRL+Alt+Del
to show what progs are running, but nothing is displayed.

Please help!

Thanks in advance,

Steve
