Are you sure about the model number? Everything I find says it's a laptop or notebook.

Is there a full model number?

not sure but this is what I find for that model number but only has drivers for xp and vista 32 bit Product Support | Dell US
edit was going by his specs not the first post

Todsy, picked up a used PS/2 keyboard and when I looked at back of desktop, no PS/2 connection.
I wish I had checked for capabily sooner so I didn't waist several days.

As for model - Dell Inspirion 531. SvcTag J26CZD1

Thanks for helping

Sorry for the confusion, I have updated original post to correct PC make from HP as WAS shown to Dell as NOW shown.
Item 6 shows I upgraded pc from VISTA 64 to Win7 64 (years ago).

So if I haven't pissed off everybody, maybe we can get back to steering me in what I can do to fix my issue of no keyboard capabily in order to reset BIOS.

As for PS/2 keyboard, I can't see that a PS/2 conversion to USB would help since USB outlets don't seem to be getting power; I have tried different USB memory sticks and no LED lights appear.

Hi all, it's been a while since last posting and just wanted to let you know, with help from another forum, was able to fix my issue.

After much trial and error, one member from Secrets forum decided (based on 50H error) my issue would be memory related issue and asked me to remove one or more of the three memory sticks. After removing first, easy access, memory stick I was able to access CMOS, then fixed sittings and all was well again with my Old/Great Dell 531 desktop. I've updated all programs and all is well as before.

Again, thanks for trying to help and wanted to provide final answer.

Also, in my previous "last" post I forgot to mention that desktop also worked after replacing the one memory stick that fixed the issue.

Thanks, again to all who tried to help me in windowsseven forum.
