Restart the system, then try to go into the BIOS setup menu. Make sure it shows that the proper amount of RAM is attached, as well as the hard drives. Exit BIOS, and press the TAB key (I believe) to watch the motherboard account for each attached device. If it shows a missing device, or the wrong amount of RAM, then that device may need to be replaced.

The OS is your operating system, which is probably a version of windows.  Reinstalling it is often a last resort, as it will wipe out all of your stored files.  It is also an easy first solution if you don't care about anything on the computer.\n\nIt's hard to know how to fix your problem because it could be a number of different things.  When you first turn your comptuer on it should go through what is called a Power On Self Test (POST).  You should hear a beep and than see a screen pop up as the computer tests all of the devices.  If all you see is a screen with a logo, such as "DELL", than your computer is hiding this test from you, but will usually at least show you any errors that come up.  We'd need to see those errors to help figure out what is causing the problem.\n  Also does the computer start loading windows at all?  If you see windows start to load before it crashes and gives yo uteh blinking underscore you can try booting to safe mode.  To do so press F8 as soon as you see windows loading, and then select it from the menu.\n\nA few other things to try: check to make sure you don't have a floppy in the disk drive, or a cd.  Check to see if you have any hard drive activity.  There is a light that normally flashes on the front of your computer when your hard drive reads or writes.  If you don't see it than you might have to replace your hard drive.

if the motherboard you are switching out is vastly different, It will not work, and even if its similar your better off re-installing windows, but if its identical, there will be no problems(any that I've ever found yet anyway)

Make a bootable cd rom and see if it boots on that.\n\nYou can even try a non-Windows OS (gasp!)\n\nLastly you could try to flash the Bios

There should be a battery inside your computer that powers the BIOS. Try replacing it and see what happens.

If you have used a power suply tester and verified that that power supply in the current computer is OK, then unplug and replug in every connection to that motherboard. Try restarting the PC and see if the PC reboots up. If you have a second power supply then take the other one out and hook that one up. If you still cannot get the PC to start up or at least get the BIOS start up screen there is no sence testing the motherboard because my friend is fried. Consider replacing it.

These are the options:\n\n1) Microsoft Windows Updates\n2) You have to refer to the specification of your system configuration to find out which brand of peripheral devices your system are using, and the motherboard chipset. Then go to these OEM to download the relevant drivers.

I had a similar problem.  I took it in to get checked and it was the motherboard.  They replaced it and I ended up paying $100.

cycle the power on your PC, make sure no floppy or CD is in the drives.  If that does not work, turn off teh machine, unplug it and open the case. Make sure the HDD is plugged in and has power. While in there, remove the RAM and the reinstall. Plug it back in and restart the box. If that still does not work, you may have a corrupted OS and will have to reinstall the operating system. Before you do that, keep in mind that it will whipe your drive of all DATA. You can try a RESTORE, before a reinstall. If you have another HDD, or are afraid you will loose DATA, spend $100 and buy a new HDD. Install it and load the OS. Then slave your old drive and pull your DATA off it onto the new drive. I hope that helps.

Check the power supply cable (the one with the 4 pins).  It sounds like it just isn't getting any power.  Even if there's something wrong with the jumper settings or the I/O interface, it should at least spin up.

Doubt you installed your OS on the external drive.You may be using it for partitioning purposes.My bet is on a bios option that may have changed when you first plugged the drive in and restarted or are not familiar with configuring bios.The options are the boot device,boot priority and the (boot to or boottable USB device).I'm sure it is that last option I mentioned
