I have a Sony Vaio PCG-71312M. My fan started making this grueling noise, so I opened her up and cleaned the fan out. Fan sounds even worse. So I go back in and find out part of the fan had melted slightly. I shaved it down, no harm down. The fan now seems to run perfectly, but then it would randomly turn off whenever it felt like it, as short as a minute and as long as an hour. I assumed there was an issue with the heatsink, but the solder is firm on the CPU and the heatsink was in place. So I foolishly tried to recover my laptop and restored my factory settings. The computer had of its acclaimed moments and switched off, leaving me with no Operating System. I've tried to restore it eight times now and at 75%, it switches off, every single time.
What I would request is, could someone please tell me why my computer could be switching off and other methods of restoring windows.
It is worth noting that there is a screw missing from the laptop's motherboard prior to me opening it and one screw missing from what I believe is a secondary heatsink. I also discovered that the button board for the power and adjacent buttons was broken and the tip. Whether or not those are relevant, I don't know. I also don't have a working disk drive, so I can't restore windows by disk.
Thank you in advance to anyone who can help.
