after a few hours computer runs out of memory..?

[wayne_uk]

Icons start to dissapear,little parts of pages go missing,programs freeze eventually etc,sometimes if gives the message ' there isnt enough memory to open this program/file '

not a major problem,as reboot and its good as,but I cant leave it on overnight etc

it feels like the ram is filling up,and not emptying >? at a guess... , any ideas ?

only things ive changed recently is the cpu,after installing a xp2800 and faffing around with clocking it these symtems have appeared,even if all is at standard settings.

Thanks,

Wayne.
