I just recently bought an HP Pavilion p6730f BV533AA#ABA Desktop PC - Intel Core i3-550 3.2GHz, 6GB DDR3, 1.5TB HDD, DVDRW, Windows 7 Home Premium 64-bit. Right out of the box it started acting a little touchy. I bought to get a project done for a client, so immediately I installed Adobe premiere cs5 along with a slew of other programs I use day to day. Within the first two days I noticed it would sometimes fail to open new programs after it had been left on for about a day. For example: lets say I go to open firefox, so I click on the firefox icon pinned to my taskbar. It glows, as if it is loading then fades. As if the computer forgot what my request was. I try clicking a few more times; same thing. So I go to the shortcut in my start menu, click it: same thing. the little circle appears next to my cursor for a moment, then the request is gone. Tried hotkeys; (windows button plus number position on taskbar) still nothing. I then try every program on the taskbar, each with the same results. (and giving proper time for the computer to think) Even simple programs like text editor will not open. To top it off, the shutdown process wont even initiate! At which point I have to hard-crash out to restart. After a fresh restart it works fine for a few days or so till this happens. I have searched all over for an answer. Has anyone experienced or heard of this before?? Thanks in advance!
