Hey guys

something is really killing my performance here on my desktop equiped with a Intel celeron D 2.8Ghz 512kb l2 cache and 1GB of ddr533 memory

i am getting cpu usage spiking in the upper 90's and only running 2 programs Firefox ( 11% cpu usage and lime wire only using 13% cpu) that adds up to 24% and im hitting the upper 90's and maxing out at 100% and i am using 550 mb of my 1024 i checked task manager and it only shows about 15 more percent of other crap running which still dosent show why im running so high cpu

any ideas
