I have a Compaq 5300US, running Windows XP. Last night I noticed the screen displaying this message.
"non-system disk or disk error
replace and strike any key when ready"
the cursor is blinking right under these two lines. the screen looks like the MS - Dos command mode screen. all black, with the error message in white letters.
when I restart by shutting down the tower with the power button..... the first screen is the the "red Compaq " and the words <F10setup> in the lower right hand corner. The Floppy drive (A) lights up... and the machine makes a series of repeating 4 clicking type sounds. then the screen goes black, and i get the above mentioned error message.
I normally leave my computer in standby mode... and this is what it it "woke up" to.
Can anybody give me some ideas as to what happened?
