Acer Aspire 7540-5750

First I'd like to apologize if there is a thread out there already for this model, however I was able to find one and didn't seem to notice a search feature on the forum to try and locate it.....perhaps there's one burried in the pages here someplace?

I've come across quite a few forums explaining the lack of power with the onboard graphics chip: ATI Radeon HD 4200. While I won't discount the fact that it's not amazing, I will state that I am able to run Left 4 Dead on the highest settings without any noticable hiccups. Great news for me as I'm a casual gamer and was a little hesitant about my purchase after reading the forums on the lack of the graphics power. Now, I haven't tried anything newer yet, so I imagine some disappointment could set in at somepoint.

The laptop has been great so far and for my first venture into the Acer world I really couldn't be more pleased. My only complaint is that it seems to run a bit 'hot' running at anywhere from a tad over 1.00 GB to 1.60 GB of physical memory usage (it comes with 4 GB so I'm having a quarter just eaten up). I'm sort of at a loss as to why it's running so high. I imagine there are just way too many processes running, and while I know a bit about computers, I just don't know which ones I need and which ones I don't, and how to go about insuring that I am able to disable the ones I don't need all together.

So, if there's anyone out there that may be able to throw some help my way I'd be greatly appreciative! And if anyone has any specific questions they'd like answered on this model (since there doesn't seem to be a forum out there on it) just ask away and I'll do my best to help you out. Thanks.
