System won't start it says you have a currupted hardrive

windows gone currupt, new installation of windows will solve the issue

try it on another computer if that dosent work you should
reformat your computer but first backup all your data by putting your another internal hardrive on your computer and move all your files you need to the empty hardrive and after that take the hardrive with all your stuff in it off the computer and then reformat the hardrive which the external hardrive does not work on and install a new operating system then put the other hardrive with all your stuff back on your computer and transfer your stuff into the hardrive with a operating system then try the external hardrive

OR
you can burn all your stuff into a CD or a DVD
OR
you can put all your stuff into FlashDrives and then after you reformat the hardrive with an operating system put your stuff back into the computer and after that the external hardrive should work

When this screen is seen with XP, the system must start up by pressing 'Enter' key. If it doesn't, the O/S might be currupted due to improper shut down. If it is the case, you have to load XP again, by inserting the system disc. Here it seems that, the system tries to boot, but fails. A clear indication of currupted O/S.

Try a remote access data recovery service like http://FreeDataRecovery.us

They do online data recovery via the internet and also offer do-it-yourself data recovery assistance.

You need to reformat your harddrive ? Hope this helps !

Normaly when you get the error that the operating system cant be found, it is a indication that the hardrive has either gone bad, or somehow some of the system files got deleted. I would say though since the hard drive light wont come on it could be the hardrive has shut down completely. But you still should see the company image of your computer when you start it up, (the bios screen)

A bad hardrive would be my first guess, 2nd problem if its not your harddrive would be a new power supply.

well if it says that then thats most likely the problem with your system. your probably going to have to send it back to sony for a repair or get someone who knows how to repair it but if you a warranty that shouldn't be a problem. I hope I helped you out.

some files have been currupted on yur hdd n u nedd 2 recover it

Without the cd there isn't much you can do. Unless you can find one you'll have to hope your laptop has a system restore option but you would also risk losing all your data doing so.

I doubt you can get to safe mode, but give try safe mode with command prompt and type chkdsk in the cmd window.

click on the start button and then click run and type %temp% and you will get the folder and please delete all files inside that folder..
click on start->allprograms->accessories->system tools->diskcleanup
please follow the above steps it will solve your issue
