My PC company sent an engineer who installed a new motherboard. Since then I have to hit F1 each time on start-up. The CMOS battery seems OK as my clock/date work fine. Any ideas please?We'll need a hint or two about the computer and motherboard make/model. Can you call the repair guy? Can you post the exact F1 message?Sorry, here is more information!

I have a Dell 9100 with an Intel D 2.8 GHz, purchased last October. This is going to SOUND unhelpful but I don't know what motherboard they fit! Can I FIND out easily from the PC? The only information I got from "Device Manager" was ACPI\PNP0C)2\17. Does this mean anything?

It's a Dell so contacting anyone there is a challenge. I don't think I have any access back to the engineer that called, unfortunately. All Dell suggest is to reinstall Windows but this is something they suggest for just about anything!

The ERROR message is "Floppy diskette seek failure"

Is there any other information that would help?They didnt plug your floppy in correctly.
if they did then you just have to open up your CMOS and reset it.

Either way reset your CMOS after you plug the floppy in correctly which you can tell if it is by opening up the case and see if the floppy is connected to the shortest Flat Gray cable (IDE CABLE) If it is then just push it in somemore to make sure it is in all the way.

First, lets establish if this PC even has a floppy drive. Many Dells don't.I know mine does not. :-/....no 3.5" floppy drive on mine either. Two CD/DVD drives but no floppy.Okay - so the problem is that the BIOS has been reset, and gone back to its default setting of looking for a floppy drive when booting up. You need to enter the BIOS (check your Dell handbook - or someone else here will tell you which key to press) and look for the option "boot up floppy seek" (or something like that) and disable it. That will cure your problem.F2 when you see the Dell logo Got a result! I have changed the diskette option in the BIOS to "off" and my PC boots normally. Many thanks to all for the advice.

I might even tell Dell so they can give the correct advice NEXT time!I'm glad you are all fixed and thanks for posting back.
