Is it a BIOS password or a HDD password? If it's sewt in BIOS, you could try to reset the BIOS to factory default (which should remove any BIOS passwords) If however it is a HDD password, it is a bit different.. you may need to restore your sytem (low level, high level formats, then reload your OS sorry but you likely lose all your data..What OS do you use? there are programs that can possibly give you a boot cd depending on whether your system is fat32 or NT.. NT is more complicated because fat32 will not read NT BUT NT will read fat32.. IF you have the ability to restore your OS then first try to do a complete restore with backup.. that way you may be able to save most of your datafiles.. if you have never accessesd the pc then just try a destructive system restore (will low-level, then high-level format the HDD and reinstall your software without any SW passwords..
First thing I would try is to get into the BIOS and unset any passwords there.. If you need more help you can try to contact me firstname.lastname@example.org with more information

No boot device means that the computer cannot find a drive that has a operating system files and therefore cannot boot up.
This usually means that the hard drive in the computer is faulty.
You need to get a new hard drive and install Windows on the hard drive, together with the drivers for the computer's installed devices and programs to get a working computer.

The orange blinking on your desktop power button says that there's a problem with either the power supply or the motherboard itself.
Please refer to this link for the diagnostic lights on dell computers.
What you can do is: 1. unplug the power cord 2. press the power button, hold on it for more than 5 secs 3. re-plug the power cord on your CPU 4. test if it the system will work.
If this troubleshooting step does not help, that means it is more likely that the problem is with the motherboard.
Hope this helps!
