Thank god for staples...i returned the hp today, and unfortunately i got the same model again. I got a Energizer UPS Power Supply, just in case this is some sort of power issue...so i isolated my computer from it. I am also using a different outlet. Hopefully this will workout well. I may buy a new computer power supply for it..i know a few of you said hps have $hitty power supplys. Would you guys reccomend this or no? Also i was wondering if there is a way to get the pc fans to run pretty fast to keep my system really really cool?
