I think the OS is XP Home with SP3. Once Microsoft support for XP ended, I used it just for old games, and it worked fine, but now when I turn it on, all I get on the monitor is
RV370 P/N 113-A62801-106 BIOS
This is a computer that I bought from Dell, but it's been so long that I can't find the disks that came with it.
What I have tried:
Replaced the internal battery, but nothing changed; and although I was getting in over my head, I burned XP_rec_con.iso to a CD and tried to start with it in the drive, but got the same result as before. Most likely BIOS is not set up to boot first from the CD drive. Additionally, although I have tried two different keyboards--one, the one I am using to write this, I am unable to type anything that will show up on the screen. I have plugged the keyboards into two different USB ports, one on the front and one on the back of the computer.
My question is: Whether the message I am getting on the monitor indicates what may be wrong and how serious that might be. Is it likely that even a visit to a PC repair shop would be useless? (I realize that there may be no definitive answer to that question and will just give up if necessary.) I would just like to be able to play the last Myst game and a couple of other old ones that won't run in compatible mode on my present Dell Inspiron 660s desktop running Windows 7 Home Premium (64-bit).
