thanks for everyones help, and this forum is great i didnt realize my pc wouldnt recognize anything more than 4 gig ram,i just upgraded to 6 last week, so i dropped back down to 2 took the 4 back to compusa and got my money back. open my case and vacuumed the dust of the heatsink and rearranged some psu wires now it runs a whole lot cooler than before even while converting. one last silly question, the fan i have on the back of the case should it be pulling air out or pushing air in??im thinking pulling air out.
