about a couple of months ago i noticed my computer has becoming more and more sluggish. my applications take longer to load, more ram to load and everythings becoming alot slower than usual. for example, when i try playing games like counter strik 1.6, i usually had my settings at 32 bit and 1024x768 resolution and i would get constantly get 60 fps and rarely slowdown. now whenever i play, i have all my settings at the lowest and im still getting alot of slowdown. i've reformatted my computer countless times, but it doesnt fix anything. and the biggest problem is, when i have alot of apps going my computer just kinda gives out and shuts off on its own.. so im assuming its hardware problems, i have only 1gb of ram and a 450 watt powersupply. is it time for me to upgrade 1 of these... or both?
