Extend Swap Memoy Size Manually

Excessive memory and cpu use when loading ‘heavy’ internetsites like runescape, stardoll, etc (my children are experiencing most of the problem…). Event viewer indicates ‘excessive page swapping’ and I tried to extend the swap memory size manually, this did not help either. It does not matter which browser is in use (tries IEXPL en FIREFOX). JAVA runs with the latest edition. No memory problems found with memory scan...,System is defragmented on a regular base,No malware found,Tried to start up without virusscan (sophos),Problem started a couple of weeks ago, system run normal before Memory use running heavy java appr 200MB ,Memory use homepage only 2 MB,PC performance index 3. MSINFO.exeinfo: 1G installed; 767 total phys mem; 116 available I wonder why there is only 116 MB physical memory available What causes the degradation: 1GB -> installed memory to 767MB total physical memory -> 116MB available memory? (and this is just after start up, no browsre loaded) Number and 'weight' and weight of boot programs is very low.
