It shouldn't be that bad. I've seen university machines running windows 7 with less than current hardware and a whole bunch of scripts, antivirus, etc, and they still boot and shutdown in a very reasonable amount of times. Definitely sounds like the hardware rather than the myriad of scripts to me. Shrug.
But conversely, there's nothing wrong with a computer of that spec, if you're doing web browsing, word processing and the like. It's just not being used efficiently.
And it was just yesterday when I stopped being a hardcore gamer and knowing about computer specs, and that spec wasn't half bad. Am I locked forever thinking that would be a decent computer?
I'm having the hardest time believing you said that with a straight face.
