O.K. here goes.... I am new to posting in forms, so I didn't follow where "this" is in Saran008's reply. I wrote down the forum number to find my way back to check responses.
To be brief. Viruses! Possibly my DVD player going bad. Downloaded Ubuntu/Linux. Opens on another computer but not the one I am working on. Ubuntu won't boot from CD/DVD. Been in Bios to change the boot using F2 and F12. Won't boot.
Managed to get into Backup last night, I now have system files on a USB Drive. In case my CD/DVD is troubled I don't know how I will get the drivers back if I reformat. Or if the virus travels with the backup files. I have a Windows XP Home program disk and several key codes, no idea which one goes to the XP disk or if it matters.
I have tried to install AVG, Malware, Avira, others and am continually told I have to uninstall Trend Micro Pc-cillan. I am asked for password to uninstall and don't have one. I am going to download freeware program removal tool next.
Been 5 years since last HDD reformat. So I'm trying to avoid killing my computer. If FDISK or other format takes and I lose everything, I suppose I will next be ordering a new CD/DVD player if Windows won't reinstall or Key code does not take. I don't want to buy any more copies of Windows.
I appreciate all help and will leave it there for now. Thank you.
