Usually when it says no operating system found, it's a problem with your hard drive.  Either your hard drive is broken, or something happened to your BIOS so that it's no longer trying to boot from the main hard drive.\n\nHere's what I'd try:\n1) find a boot cd, put it into your CD drive and start your computer.  If it starts from there, try entering C:<enter> to find out if your hard drive is working or not.  You'll know it's working if the computer writes back C:&#92;>.  If it writes back something about not finding the C drive, you know your hard drive is the issue.  You can run chkdsk on the hard drive to find out if it can fix it, but if it's not even registering the drive, it might be fried.\n\n2) If the computer does the same thing with the boot CD in as it does when it's not in, there's probably something going on with the bios.  I'd try to find a cheap non-usb keyboard so that you can get into it.  Look at the boot order and make sure that the hard drive is set as the primary, then make sure it will fall back to teh CD drive if the hard drive doesn't work.  At this point try step 1 again\n\n3) if none of this works, call the nearest geek and get him/her to look at it.

You can try booting from a XP installation cd and try repairing the system. Chances are that youre hard disk is damaged, try running a disk diagnose program and see if this is the case. Hope not, cause you'll have to get another one then

Restart the machine.\n\nIf it stills boots into safe mode, restart again and hit F8 a few times.  This will bring up the boot menu.  Select Normal

Boot the computer up in safe mode by pressing F8 a couple of times before the windows loading screen appears and select safe mode. If the computer boots you have a problem with one of the driver files if the computer does not boot their is a corrupt main driver file. If you get it running run a scan disk for when the computer is next turned on this should fix any file system errors. See how you get on.If your computer does not boot you might have to reinstall windows making sure you reformat the hard drive (worst case)You might also have a program trying to run when you turn on your computer which has an error causing your computer to screw up.

Could be anything of a million and one reasons.\n\nTry taking the CD back out and see if it boots now.\n\nYou might have zapped the motherboard with static.\nYou might have unseated the RAM.\nYou might not have hooked the power supply back up.\nYou might have...\n\n///

The hard drive may have failed. Go in to the BIOS and see if the drive is found.

Restore to last known working configuration === turn on computer and start tapping the F8 key. You will get a prompt. Select this option.\n\nIf that dont work, do the same thing, but go into safe mode as administrator. From there, its a whole new troubleshooting process. Disable all your startups in MSCONFIG and try again.

go onto ur BIOS settings\nand check boot settings

Try starting it in safe mode (hit F8 while it is booting).  If it starts in safe mode and does not freeze then you obviously have a software problem.  Try using mscong to stop a few things in your start-up, beginning with your anti-virus program.  Keep track of what you turned off and back on and you will eventually hit the problem program.

most likely, your boot file is corrupted. put your windows xp disk into your optical drive and reboot from the cd. go to repair console and repair the boot file

Right click on My Computer icon> properties>Click on Advance Tab>Down at the bottom find Start up and System Recovery> hit the settings> uncheck---Under System Failure----Automatically Restart..\nThat should take care of it temporarily.\nU might wanna rebuilt your PC from scratch...U might have some other serious issues which is causing it.\nGood Luck.

Somethings to do will be;\n\nOpen the computer and check all cables and connections\nRemove the CMOS battery to reset the Bios\nDisconnect any hardware that you don't need to boot up\nTake the Ram out and then put it back in\n\nIf none of this helps then it is either a power supply problem or the CPU is blown and the only way to find out which one is to remove it and test it with a working one.
