I returned from a months vacation to find my desktop (old runnings office windows) disabled. When signing on typically, Windows tried to open but was quickly replaced with a "corruption" warning of a blue backdrop screen. Saying windows is not opening due to danger to my computer. Suggestions to unplug and reboot was tried. Same blue screen ending as follows:****STOP: *x******** (*x********, *x*A*EBA**, *xc******, *x********)**I left the state with two windows files minimized, probably a bad thing to do. Now I can not get windows to even open. Am writing to you in desperation the desk top is my main tool for my business. Please help. Just above the numbers and letters restated above the blue screen statement suggests: Run CHKDSK*F to check for harddrive corruption. But of course I can't even get windows to open nor do I have a check disc ?!*If I ever had one. I email you here from an unrelated lap top.
