hi, I have a problem with my Dell Studio Xps 1640 laptop and its hard drive disk which is Toshiba mk5061gysn. 3 days ago the lcd turn blue and after that when I started win7 at the first instance everything seems fine but when I wanted to do something everything just freeze. I decided to install win7 again but when I reached the step of choosing hdd partitions, there wasn't any and I faced with this error "no drivers were found. click load driver to...". Afterward I downloaded some mass storage drivers and then click load drivers but none of the drivers match the hdd ,if the system could actually detect an hdd device, and that's it. Please help me through this.
