I recently upgraded my computer from an AMD 64 3500, 1gb 2x512mb kingston valueram and a Asus A8V VM mobo.
to a Intel Core 2 Duo E6320 4mb cache, 1gb stick of ddr 4200 kingston valueram on a Asus asus p5vd2-mx se.
I have a basic 500w switching p4 psu.
Since the upgrade my system feels alot slower. I did a fresh install of windows, and i noticed that when i changed my resolution to 1280 i had 3 attempts before the resoltuion changed, the screen went blank, games are very choppy stopping and starting at random intervals, the hard drive feels like its loading a lot more than it used to. I was installing the gfx drivers (7900gt) and the mouse kept freezing and then starting and so on and so on.
When i first installed the upgrade my cpu temp was 25c idle, now its about 35 idle and last night got up to 41. After the fresh install i tried to test my computer with FEAR, the game went sorta nuts on me certain parts of it were skipped it wrong places and everything just feels really wierd now.
I have no idea whats causing this but i thought it may have been the power supply playing up, others have suggested the memory.
Thanks in advance!
