As with the previous answerer, check the BIOS/CMOS setup and see if the system is set to boot from the hard drive. If it is, and there is no diskettes in either the DVD/CD drive and any floppy drives (if you have any), then it means that the boot partition and Windows system files were corrupted. At first glance from what you described in your question, it looks like your system is trying to boot only from the Ethernet Network Interface (NIC) port. You would only boot with PXE turned on if your system is hooked up to a server or another PC or Windows-running Intel Mac with the Windows or Linux operating system installed on the other machine. Since you are not going to be doing that, go into the BIOS/CMOS setup and turn-off any Network booting (PXE enabling). If your system has Serial ATA (SATA) based hard drives and CD/DVD drives, then set the SATA configuration in your BIOS for SATA Raid to "Autodetect/AHCA" if this option is available in your BIOS.
If this does not resolve your problem then hopefully you made backups of at least your data files (ie. Word documents, Photoshop images, MP3 audio files, etc.) This way, at least all you have to do is reinstall your operating system software and the applications, but you will have not lost your important personal files and data. If you have your Windows installation DVD, you will need to insert it into your system, and tell the system to boot from the CD/DVD drive. Usually when your computer boots up, there is a short-lived splash screen with the computer's BIOS makers logo on it that appears just before either a Microsoft Windows or Linux splash logo screen appears. During this time, look for any options to any keys that will take you to a boot-menu, this will allow you to temporarily change the boot order without making permanent changes in the BIOS. Once the computer has started the Windows disc, and if you are installing WindowsXP or Vista, let the system reformat and repartition the hard drive for NTFS file system, and tell it to use the entire hard drive for a Windows installation. My suggestion is to always let Windows install every option it has on your hard drive on the first run. You need to also locate all of the installation CDs/DVDs for your apps, and then reinstall them as well. With your backup of your data files, I would take the disc that they are on and then copy the files back on your hard drive to the "My Document" directory (many cases Windows puts a shortcut-link to this directory on the desktop).
P.S..Sometimes power supply units actually get detected by both the motherboard and Windows/Linux OSes just as hard drives, monitors, video cards, and iPods get detected. Most of them use only basic driver software related to power on/off options such as "sleep", "system shutdown" and "standby" that are accessed and configured in Windows, but each manufacturer may use a different driver software, therefore this could also, however slim chance, affect a Windows installation as well.
Go into bios and make sure your system is set up to boot onto your hard drive first. Make sure your cd-rom and floppy drive dont have any media in them. If you have a non-bootable CD or floppy in a drive and the bios tries to boot off it you will get that message. Make sure your hard drive has power to it as your bios may see it but wont boot to it without the drive having power to spin it up. Also make sure your hard drive is configured properly in bios. If that doesn't work try going into bios and have it load setup defaults and see if it will boot. If it does you may have to go back into bios and modify it to enable onboard sound LAN etc. Hopefully you won't have to reformat your drive as sometimes they get effected when a power supply fries.
it sounds like you have a corrupted boot record but dont panic as the fix shouldnt be too difficult and this is assuming that your O/S is windows xp.
1st go into the bios and set the boot priority to boot from cd 1st, then insert your windows installation disc into the cd drive then press the F10 key to save settings and exit.
2nd the pc will now reboot as it reboots you will see press any key to boot from cd so press the space bar windows will then start to load files as though installing windows, follow the sequence untill you are asked if you wish to install windows or REPAIR windows clic on R for repair, leave windows to do its thing untill you are left with a flashing cursor, now type in HELP and you will get a page of comands press the space bar to move the page to the bottom untill you once again get the flashing cursor and type in FIXMBR it will ask you if you wish to REWRITE THE MASTER BOOT RECORD PRESS THE Y KEY THEN ENTER it will then tell you that you have rewritten the master boot record.
3rd once again press the space bar to get to the flashing cursor and again type HELP at the commands page again press the space bar to get to the cursor and this time type in FIXBOOT and press enter again it will ask you for confirmation again type in y and press enter once the boot record has been rewritten press the space bar to get to the cursor and type in EXIT press enter and the pc will reboot and hopefully all should be ok.
