http://speccy.piriform.com/results/zcOU6lhwSp8yrqILmNwNbJm I have 512 + 1 gb, not 2 gb as speecyshows http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=774C43F331D926C3 my cooler: http://www.amazon.co.uk/Xilence-Intel-COO-XPCPU-P4-PRO-Cooler-Socket/dp/B000WVIKPO my psu: http://www.onyougo.com/everest-eps-1600a-power-supply-units_pi1543622 I have 3.2 ghz p4 now, and temperature is around 80 c if I open tabs, normally around 67. Also I have 2.8 ghz, with that temperature is around 40 c. Maxtor hdd's temperature is maximum 42 c . For example if I open a lot of tabs or videos, ram goes low and computer starts not to respond and maybe a few seconds freezing. I will buy 1 gb ddr ram or more to solve this problem but what about cooling? IS that cooler necessary ? What will I gain if I use 3.2ghz instead of 2.8 more than having high temperature, I cant see any difference maybe because of 1.5 gb ram. Should I buy new rams or new cooler or use 2.8 ghz?
