So I'm trying my best to restore an old Sony Viao laptop for a friend, when I first received it I found it to have a completely dead harddrive so I sold him an old unused 500GB that was sitting in my room.
Re-installed windows on it and it froze on the personalization screen (Win 8.1)...so I was tired and just let it sit over night. Today I was able to get into windows and all and started to install some things when it froze again. I was thinking maybe it was some kind of thermal overload and freezes as a safety precaution. I just blew out the cooler, repasted it (the old paste has literally become solid rock, I've never seen paste harden as much as his had). The fan definitely is running less and quieter BUT the thing still freezes.
I've tried removing a RAM stick and it seemed to buy a little extra time but STILL freezes , I've alternated the sticks running just one at a time and it just freezes. I have no idea what could be causing this issue, I'm at a complete loss but really want to get this laptop working again because it has a sentimental value to him. Any suggestions? I figure the only thing I could try now is pulling the bios battery and resetting the bios but I doubt that'll help.
