You can read this KB, I hope it will help.
Popko37197, try these trouble-shooting steps.......
Try clearing the NVRAM (CMOS) to see if it resolves the boot problem. Possibly the information stored in the NVRAM (CMOS) became corrupted or has a conflict with the newer BIOS version which is not uncommon. Normally you would clear the NVRAM (CMOS) by entering the BIOS Setup, but it would appear that you can not do so. The alternative would be to remove the battery from the motherboard to clear the NVRAM. With the machine unplugged from the wall remove the battery from the motherboard. Then with the machine still unplugged press the On button for 15 seconds to dissipate any remaining electrical charge on the motherboard. Then re-install the battery, plug the machine back into the wall and see if it will boot normally.If the machine still fails to boot then strip the motherboard down to the bare minimum. By bare minimum I mean remove all expansion cards, disconnect all drives and leave just the processor, memory and graphics card in the machine. On models that have integrated graphics, remove the graphics card and use the integrated video port. If the computer boots this way then start connecting each device one at a time until the no boot scenario returns. This would then indicate which device has a conflict with the newer BIOS version. Also try booting the system without the keyboard, mouse or any other device plugged into the rear of the system. If this procedure doesn't resolve the problem then you maybe looking at a situation where the motherboard has failed due to a bad BIOS flash and needs to be replaced. Considering the cost of some of Dell's low end systems it maybe cheaper just to purchase a new machine. Any of the low end systems will outperform the model you have now.
