I have a Dell Optiplex GX270. A few weeks ago I replaced the motherboard (with all of your help) because the capacitors had blown and it has been working beautifully.

However,

I just tried to use a CD, and the computer didn't recognize anything in the drive. Same for a floppy, in fact. Those were working fine before I replaced the motherboard and the whole computer started going awry. Using a thumb drive now works fine.

I checked everything I had unpugged when I reinstalled the motherboard by unplugging and replugging, they alll seem fine. The wider plugs with many pins towards the front of the machine I can't even unplug, so I left those alone.

Do you have any ideas or suggestions?


Thank you in advance!

Just to add, this is a Windows XP-SP3.

In System Device Manager, the CD drive and Floppy Drive are both marked +, just like everything else.

Did you connect the hdd with Windows on it to the new motherboard?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

When I connected the new motherboard, it worked perfectly. I'm using it now. The computer works for everything else. I just hadn't used the CD or floppy drives yet and when I tried, they didn't work. The light goes on inside the CD-ROM, though.
I rechecked all connections on the motherboard and they are all corrrect and firm.

I booted to the BIOS by pressing F2, and from then on, I'm not quite sure what to do.

I wish I was able to post a photo of what the screen looks like. I'll describe it for you.

Starting from the top there is:

System Time

System Date

Drive Configuration

When I click Enter on the Drive Configuration, I see

Diskette Drive A...................................................Not Installed

SATA Primary Drive.............................................Off

Primary Master Drive...........................................Hard Drive

Primary Slave Drive..............................................Off

Secondary Master Drive ......................................Off

Secondary Slave Drive.........................................Off

IDE Drive UDMA ....................................................On

However, I am unable to change any of the above settings. I tried to change the setting for Diskette Drive A by pressing on the space bar, the +, the -. nothing worked.

Do you have any suggestions?

Also, which of the above apply to the CDROM drive?
