Too many processes running on my computer
My laptop has like 9GB of memory and should be running at lightening speed because it has so much memory. I have deleted ALL programs except the programs that came with the computer (the basics), yet my usage says that I am using 5GB of memory which seems a bit excessive for the very few programs I have stored. The computer runs like a snail. I've defragged several times, deleted cookies and temporary files and then defragged again. I went into task manager and I have like 30+ processes running at all times even when I don't have any applications running. That seems like a bit much plus when I do try to run an application, if it has a lot of graphics the computer says I'm low on virtual memory (which I shouldn't be because I have 9GB which is way more than I should ever need) So all you computer savvy people, what could I do to correct this and what processes SHOULD be running even in downtime. I know that I can end processes, but I only want to end the ones I don't need.
Also I know that there is a combination of keys that stops all programs from starting when the computer starts, but I can't remember the combination, I think that this would help so if anyone knows that key stroke combination I'd appreciate it.
Thanks
