The 8400 is a problem chip. If you are serious you would research then learn to replace it.
I?ve been playing World of Warcraft on and off for 3+ years. The game has always run smooth without issues until recently. Now when playing the frame rate only seems to go as high as 25 which is playable and will frequently drop to between 7 ? 10 and is totally not playable. This fluxuation in the frame rate happens often. When it drops down to 7 ? 10 it usually last a few minutes and go back up to 20 ? 25 for a few minutes and drop back down again. When the game was playing well, the frame rate would get as high as 50 ? 60. This is very frustrating. My PC is an HP m9040n.
