I have no idea what is causing this so I've turned to you guys for help I've tried a hard drive scan, windows 7 memory test diagnostic, registery cleaning, moving ram around ram slots, updating drivers but nothing works.
Basicallly a few months ago every now and then my computer would freeze for around 7-8 seconds. However now that can happen but is what is worst is WoW has gotten really laggy sometimes it acts as if I'm about to DC I can talk to people fine they can hear me but everything else does not work I get the feeling the two are not linked. I've been pinging google normally its fine and my ms is around 40 however I pinged it today  for 120 seconds when WoW started having these symptoms again and the results where.
A range of latency lowest being 31 highest being 1348, average being 429 with 8 pings being lost
