I have a Toshiba Satellite L655-S5157. I have been getting the blue screen of death every so often for awhile now but now it's all the time. Ive run diagnostics on the computer and it's without a doubt a failing hard drive. I installed a new hard drive and went to re-install the operating system (windows 7) from disks that I got when I purchased the computer only to learn that the disks are only repair disks. So the issue I have is where on this hard drive do I/would I find the files I need to install on the new hard drive. I never backed up my system because 1. I thought I had the os on disk and 2. I save everything to an external hard drive. Can you please advise. I thank you in advance for lsl your time and attention in this matter.
