Sounds as if your resources are very low. to check them right click on my computer then go to properties. Click on your performance tab and the second line down is your system resources. If they are under 80% then you should bring them up some. Go to start/run then type in msconfig then press OK. Go to your startup tab and then uncheck what programs you don't want loading when your computer comes on, when finished click apply then OK, it will ask you to reboot, say yes then when the computer starts up try to run these programs.
