Question : Problem: Rom Drives and Hard Drives not detected in BIOS

I have a Dell Optiplex 270.
About 3 weeks ago I added a CD burner.  Worked great.
Then a couple days ago it stopped detecting both the hard drive and the cd-rom drive.
I have tried other hard drives to no success.
I changed the CMOS battery flashed BIOS to it's current version.
Nothing works.
I did get a SATA drive to recognize in BIOS on it but that is it.
No rom drives or IDE Hard drives get detected.
Could the IDE part of the motherboard just up and died or is there something else I could try?

Thanks

Assuming you have tried another IDE cable, it sounds like it could be the IDE controller. You could try disconnecting all drives apart from one and seeing if that gets recognised. Then systematically add each device one-by-one. As it was working before, I doubt it is a jumper issue. How dusty is it inside the PC, there is a very small chance it is just a build-up of dust and scuzz. Use some compressed air if you have it, and maybe a non static brush. I once had a machine where somebody left a stand-off on the chassis and it was shorting and causing the same effect.

So, if noe of the above works, your only choice would be to replace the board or buy a specific PCI IDE controller card.
