Thanks and its ok, but you should probably edit your posts so they're a little less offensive. I've already done so with mine regarding the upgrade debacle. You seem to have generated yourself a very poor reputation very quickly here, so trying to rub that out would be a good idea and things can be running smoothly again in no time.
My parents own a 8-9 year old sell-and-run that has no business running, but that machine alone was the source of both memory and mobo issues in two separate incidences. Buying any OEM machine is kind of hit and miss, because no matter what way you look at it, they're trying to make money off their products. The easiest way to do that is skimp out on the quality of parts just enough that it runs without blowing up. I've actually heard numerous people on this forum say HP is only marginally better for reliability and quality than Acer, and I'd be inclined to agree.
Who knows, maybe I'm just bitter because the computer I grew up with was a PoS, or maybe I've had a localized pocket of lemon HPs in my area. I only come here to give opinions, I'm not saying I have the final word on anything, I'm just contributing to the pile of information the OP has to weigh and consider in their decision.
