I am having issues with my sony viao pcg k23 laptop

Last night firefox was acting up, not allowing me to create a tab or browse, so I restarted the computer and it did not load past the Vaio load screen.

I shut if off, removed the battery and let it sit for an hour and came back. Same issue

so, I removed the ram and then re installed it. It got me to the windows log in screen and it didnt give me any issues.

well, 2 hours ago it did the same thing so I did the whole procedure and got nothing, frusterated and wanting to run check disk I am on the misson to reset the CMOS by removing the cmos battery, but I only have a pocket knife and it cannot remove one small screw to remove the stainless steel panel that covers the mobo.

My friend, that is a service admin for my old high school told me to boot chk dsk through my xp cd... but when I bought the laptop 4 years ago it didn't come with an XP cd at all... nor did this computer I am on now.. pretty gay. So he is going to load an image on a file server for me as well as some driver upates since some might have gotten corrupted.

still waiting for my bush bucks so I can upgrade my laptop to something new...frign sony viao, battery lasts like 10 minutes, slow as crap, etc...
