I think hp and compaq are now the same company? They joined there company recent years and sometimes if you buy Hp they will send you compaq
seriously get a mac if you can afford it. You will never go back to a PC if you do. Now you can run XP on mac's.....they are very much so worth it. If you don't get a mac get a HP.
I had the problem with overheating, after a while i had to down clock the CPU in order to work properly. I mean come on down clock a CPU from the original spec thats crazy. While most people over clock i had to do the oposit just to be able to use it.
