Hi! I am facing a very weird problem. I had windows 7 in my HP Notebook which was running too slow and lagging at times, I thought I should do system restore and did that using HP tool. It was completed successfully, However the very next day it took showed bppt error and took me directly to startup repair and did not show any issue. I reformatted it. and this happened atleast 5 more times when one of my friends suggested I should do a clean reformat and install new OS I did that. My PC worked well for a week and the same problem reoccured. ever since, I have been formating my PC every 2-3 days. Please Please help me with this! Is my hard disk at fault? no disk check shows any error.
