Support remote access is used to determine what was going on with your computer: drive, operating system, right?
In Central America, technical support advised me to find someone to transfer files on an external hard drive and then call the person, technical support to reach my house. I needed a professional to pay for the transfer of data completely, but it had transferred some of my files, the sensitive and confidential information to a 640GB external hard drive. The payment of "interim" cost of nearly 200 professionals are on hold to move data from a small device. After re-call technical support (currently in Manila) and remote access is established that the drive is not inferior, but there was no need to replace the memory modules. The rendezvous technique was developed in less than a minute when they finished installing the new memory modules, it seems that all my files are on disk. Although I do not understand what happened when he got the blue screen, then I want to transfer and / or backup my files often. How can I overon drive C "in process", rather than the transfer of each file individually. System is Windows XP.
