I have a lovely Sony Vaio vgn c2m notebook which has a t5500 processor. I have a Vista gadget which records the amount of ram and CPU used. It never seems to go over 1 gig. I have 2 gig installed. But somethimes it hangs for a coupe of seconds.
Also, is it possible to alter the amount of RAM used for the graphics? It has Intel Graphics Media Accelerator 950 on it.
freezing/not responding programs is not a memory problem - more an issue like a slow connection or bus, possibly a slow processor. It's more likely to be a software problem than a hardware problem, though. Does this occur widespread, or only in certain applications?
For the bios, consult your manual. Look into your notebook online, it may not support a feature like that.
