I've hit a point of frustration with my VAIO. Out of nowhere (no new program installs, viruses, spyware, or registry changes) I would get a complete and utter lock up to the point where the only restart method was pulling out the battery. The freeze would occur about 10 minutes into usage each time and CPU and MEM usage would be at 100% spike with the fan running full throttle. There are no unusual noises from the HD unless laptop is resting at an unusual angle on my lap, and it's done that since brand new... as have other laptops of mine.
I did a scandisk (no problems), reformat, and reinstall of Windows.
I'm guessing this may be a RAM issue, but before I throw out wads of cash to replace the sticks, are there any suggestions out there? Hard drive issue I may be unaware of? fautly chipset? bad CPU? Simple software something or other?

Please help. I am computerless at the moment and the library PC depresses me.

I think I would start by blowing the dust out. It may be overheating:

It's a V-505bx. I've cleaned what little dust was in the chasis, but I'll get a can of compressed air.

How old is it? I've seen heat sinks on desktops completely clogged. I would make sure it's cleaned out. If it were mine, I would take it apart and make sure. You could spend several days troubleshooting hardware and get nowhere if it's plugged up with dust....
