World of Warcraft®

Hey there, so as the title says my PC is getting huge lag spikes now and then -- saying that, it's more often than I think it should happen. It's not only in wow, out of WoW sometimes also, it's getting beyond the point where I have to restart my computer ALOT.

So since I'm not really smart with all this 'techy jazz' I'll just link my specs now and hope one of you delightful people of the forums can help! :)

(I wasn't exactly sure what to put, so this might be alot of useless information to you guys :s)

Possibly an out of date addon? Also try run a diagnostic on your computer aswell as a virus scan.
If all else fails then it will be network problems

Have you checked the phone line, i was having the same problem and it was the phone line. Next time it happened to me i found out i was paying for a for a 40gb connection which i though was unlimted i had downloaded to much and they capped my internet connection change to unlimted and problem solved.
