I have a Dell Inspiron 530 with a Core 2 Quad processor, the Foxconn DG33M03 motherboard and 3GB of RAM. It's running Windows 7 Home Premium SP1. If I disconnect the power supply and do a static discharge after shutting down the unit, when I restart it the bios reverts to the original date and time (2007) and it looks for the non-existent floppy drive. I can enter the bios and reset date, time, FDC and floppy drive settings then restart and it runs perfectly. If I shut it down but leave the power supply plugged in and switched on it retains the bios settings but the next time I shut down and remove the power supply it reverts again on booting up and shows me the floppy drive seek error message. I have replaced the CMOS battery twice with new batteries and have checked that the bios version is the latest but all to no avail. I suspect a bios chip problem but would be pleased to hear other views and opinions on this.

One thing you can check is the reset jumper for your cmos, if by any chance it was left on the open 2 pins (pin 2-3) it might cause it to reset itself, make sure it is on the correct pins (1-2). If your reset pins are the other option (jumper in to reset, jumper off to keep value) then check and make sure no jumper are on the pins.
Hope that helps

Thanks for the reply.
Two settings for the jumper - 1-2 = clear and 2-3 = normal (default) settings. The jumper is on 2-3. When I tried it on 1-2 and tried to power up there was absolutely no response from the machine.

Sorry about that, guess Dell are different than usual, is it's on normal but does not keep the settings when you unplug the power cord and you have installed a new battery then it might be caused by:
1- The new battery was faulty, try a new one
2- Your power supply is causing a short that is masking the battery to be drained right away (shorted)
#- the battery is good but the motherboard battery socket is faulty (bad solders)

I concur with Alzeimer about the board. You have already done the cmos battery again. The only other option is the board. I doubt the power supply though, but if you have another to try it wouldn't hurt.
