Windows 7 Professional 32-bit Intel(R) Core(TM) 2 CPU 6320 @ 1.86 GHz x2 4GB RAM My Win7 started to freeze while I'm using the computer about a week ago. It accepts no input (no cursor movement, cannot type etc.). After a while it began to freeze up on boot up, at the same certain point (when 4 colored lights began to fly around when it says "Starting Windows"). I've tried to run diagnostics, ended up in a freeze. I've tried safe mode, booted up (yay!), followed by a freeze. In F8 menu, there was some repair options, they failed to start. Startup repair also failed to start. But sometimes when I'm lucky, Win7 decides to boot up normally. (So I can have a little chance of recovery.) I don't think the problem is hardware related because Linux (which I'm using right now(64-bit)) runs pretty well! I have found and modified a boot loader to use it as a "BIOS booting test" and it also works pretty well. As my last chance, I'm thinking of reverting the system back to a previous date or a fresh Windows install, but I don't want to lose my data. Backup will need a lot of effort in my PC. Is there any other data-destruction-less solution?
