Question about Dell Dimension C521 PC Desktop
When I boot my computer it says keyboard failure and diskette drive 0 seek failure I've tried a couple of different keyboards that I know work because they work on other computers my computer has USB only I think i know how to solve the diskette failure but I can't do anything without a keyboard
Been trying to figure this out for weeks have you tried a Dell keyboard It has worked for others but not for me and no It won't boot from CD because u need the keyboard to press any key to activate boot I even tried a flash drive to boot but my boot sequence was messed up as well I had the same problem after trying everything from pulling jumpers resetting cmos battery and resetting bios making it worse got stuck at black screen keyboard failure and diskette drive zero failure I have no floppy drive installed even tried putting one in no luck then trying three different keyboards and calling Dell about inferior design and being told I had no warranty and they won't replace their faulty hardware my next plan was to purchase a pci card for the old school ps/2 purple and green keyboard and mouse inputs and try that otherwise people online also said to try a powered usb hub and see if that helps but before I purchased anything I gave it one last go and I remembered my buddy had broken his front usb port I checked it out with a flash light and sure enough it was shorted out inside the prong was bent and touching the inside of the usb ground I powered it down unplugging the power pushed the power button again to remove any power from the power source and took a Bobby pin and bent the usb prong so it wasn't touching anymore sure enough that was my solution no more unresponsive keyboard it booted right up and when I pushed a key it bleeped I knew I was back in business so before you purchase anything from a pci card or a new montherboard check all of your usb inputs front and back for damage and I hope that helps you how it helped me currently installing a fresh Windows Vista right now :)

How old is the computer, could it still have warranty? USB ports are often protected with fuses. Some latest stuff has resetable fuses, but many are one-time that do not heal. Did you try the keyboard in the front USB's The thing of biggest concern though is that this happened in coincidence, meaning you may have a motherboard hardware failure. (the reason I mentioned warranty)
