Ok, i installed windows 7 on my computer:
Toshiba satelitte a300-034.
intel centrino core 2 duo 2.0ghz
intel gma x3100
It worked really fast, smooth and efficient until it slowed down a bit. i use a gadget on the sidebar to see my computer power usage. So i look at it one moment it says 38% ram used. A second later its hanging out around 90%. quite strange and i was struggling to open up firefox so i rebooted. as soon as the windows loads up my ram is still over 90% used. i restarted more then 3 times after that and still the same thing. I am pretty confident tht this maybe a hardware problem but not completely sure. i have had a hardware issue with my ram and its been replaced once before. from then my laptops has worked fine (about 3-4months) running on vista. im pretty sure this isnt a windows 7 problem as i noticed it on my vista a couple days before upgrading. you might even say it was one of the reasons why i upgraded.
As of right now my laptop is useless becuase it works much much slower then a old windows 95 pc.
Anyway all help would be greatly appreciated.
