@Lelouch: Well, I would recommend trying to get to MSconfig. If you can, try to make it so the computer only starts basic services.
Then do you have any virus software? Malwarebytes is good, and you can also use avast and AVG. Be sure to scan for them in Safe mode.
And you can also hunt for things in task manager that are eating a lot of memory. End task and all that. Which I would recommend.
Also, scan for viruses in SAFE MODE, which is something you need to do as soon as the computer starts up.
@PF: OK....let me take a look.....If I can.
Actually, you have a lot of stuff I got. All the half lifes, Original Fallouts....Portal, TF2 now. But yeah, you got quite a few games!
