The blue screen of death is your answer...Write down the number sequence and then go to Microsoft's website and do a search on the first sequence of numbers. It will point you in the right direction. Most likely, you may simply have corruption in one of your driver files. No need to panic...If all else fails, wipe and reinstall your OS. Your license key will be on the bottom of the unit. Borrow a copy from someone else who has the same version of Windows and use your license key to install and you will be back in business (excluding the frustrating driver update/install portion which you can find at Sony's website)! Personally, if I got a used system, the first thing I'd do is wipe it clean.

if this is new and you have none of ur data on it, just reinstall win xp if this doesnt fix the problem yes...there is a hardware problem and have been screwed...
