This is perfect! I am older than dirt and started on Windows 3.1 (and used DOS before that. Anyone remember storing your info on a cassette with a TI computer?), so I've seen them all. Windows NT was my favorite, followed by XP, but 7 is acceptable. Both of my kids have 8.1 and that is what I now have at work. It is so dysfunctional and not work efficient, I could never own 8.1. Touch screen takes forever and gives you one more thing to clean off. I can hot key at warp speed, so why change, right?
It's possible my fan is just gunked up. I remember when my son's old laptop started overheating, I switched out the hard drive, and it started working well again, but I also cleaned all the grime out of the fan, so that will be my first go to. I'm running the risk of never being able to get it back up if I disassemble it, so before I jumped off the cliff, I wanted to know the consensus. This place is so much better than geek sites, because most of you are real users, not power-let-me-tweak-my-computer-into-weird-configurations-and-wonder-why-I-only-get-two-years-out-of-it users.
Thank you to everyone who has contributed so far. I will continue take any and all opinions until I get up the nerve to operate on my poor old Toshiba.
