I'm trying to fix my husband's PC. The tower could be turned on but the monitor remained black. I opened it up and made sure the components were firmly seated. The CD Rom drive seems a little wobbly but I can now get into the Dell startup screen which I couldn't see before.
I've read the threads about this error message, however, when I go into the Boot Sequence it reads as follows:
Onboard or USB Floppy drive (not present)
Onboard SATA hard drive (Not present)
2. Onboard or USB CD Rom drive
The PC is a Dell Optiflex 755 series, BIOS revision a08. It's as old as the hills. However, it is just fine for my husband who is something of a luddite and doesn't use it for very much other than browsing and the occasional document creation.
Thanks for your help with this.
