Please do not hijack someone else's thread. You should always start your own. But this one is abandoned so we will proceed.
I try f2 to get to the bios screen but a different screen shows up (listing system time, system date etc.)
to enter Setup
will bring you to the Bios screen which will list the System Data and Time. It also lists your HDD and Memory. If your press F12
at bootup you can run the Dell Diagnostics,
to test your HDD and memory.
If you have ax XP CD you can boot off of that and get to the Recovery Console
and type chkdsk /R
and press enter. Check Disk will check your HDD for integrity.
You can also backup your files using an Ubuntu Live CD
and back them up to an external USB HDD.
