I was updating my Windows XP with the service pack3 when i tried to cancel it half way through. When i hit "cancel" my computer froze so i shut it off (not properly). Now when i try to start my computer it starts to the point where the Windows XP logo comes up then it shuts down and restarts again (it does this over and over again until i shut it off). It does give me the option of starting in safe mode, or to the last good config, but either one doesn't work. I even did the F8 thing and tried all of those options, but still nothing.

If anyone out there can help me i would be sooo grateful!!
I do have my XP CD and tried putting it in but it doesn't do anything, is this a lost cause?Right click on My Computer, click Properties, select Advanced, select Startup and recovery and de-select Automatically restart and click ok, ok. The next time you restart your computer it should show you an error code. Please post all of that error here.seriously!!! MY COMPUTER WILL NOT START UP!!! WHEN I TURN IT ON IT NEVER GOES ANY FURTHER THAN THE WINDOWS LOGO THEN IT RESTARTS, NO MATTER WHAT MODE I START IT IN IT KEEPS SHUTTING DOWN AND RESTARTING, THERE IS NO WAY FOR ME TO GET TO THE "MY COMPUTER" ICON OR ANYTHING THAT REQUIRES TO GET PASSED THE WINDOWS LOGO SCREEN AT START UPStop shouting in All Caps and try the procedure above in safe mode...
It's not our fault you are having issues...your right its not "your" fault i am having issues but it is "your" fault that you come on a computer help SITE and dont help!! if you were here to help then you would read, i clearly wrote that my computer doesnt start up even when i try safe mode, making it impossible to try the earlier stated "help" blog. The sad thing here is that i just went to Office Depot yesterday and talked to one of the cashiers and they TOLD me to try something that worked perfectly and now my computer works!!! so i am GOING to repost what i was told so someone on this site can get some real help!!
-While computer is starting up hit either "delete" or "F1" to enter set up mode.
-select option for "BIOS" settings
-make sure your "CD" drive is first to boot
-restart your computer with your windows install CD
-your computer will read the CD and take you into install/set up
-follow the prompts and you have a WORKING computer again!!
***note that this only works if you have your windows installation CD***
