Lag on 1 PC, and only in EQ, any ideas?

[Etaria]

Not sure if anyone can help me or steer me in the right direction... Please forgive me in advance if I should not be posting this here- as I do not think it is EQ related, (hence the apologies) but since it is affecting eq, I figured why not give it a shot here; maybe someone knows what little mouse is eating my machine and taking away my escape from the real world.

One of my PCs is constantly lagging in game, (I am nonstop getting that warp message) in eq. I press spells, and my button stays depressed for however long it decides to at that moment. Tels can take a minute to go through. This is only on this laptop. My other other laptop and desktop, nothing, run perfectly fine.. no lag in game.

I've tried resetting my router (also changed the password); tried resetting my modem. I have ran malwarebytes, spybot, I've also run panda online scanning for viruses and such. I run AVG. I also tried restoring my windows to an earlier date.

One thing I did, was downloaded 3 programs to try and watch DVDs on my laptop (since win 8 does not have win media for movies). I am unsure if I got some crazy virus, but AVG and all my other scans aren't picking it up.

I have been loaded with work, so I haven't been on and was hoping the lag would be gone and maybe attribute it to being a fluke. I log in tonight, and same thing.

I'm not super computer savvy, but I have always been able to get viruses and such off (though I haven't had any in a few years) and figure out little computer problems.

Anyway, if anyone has any ideas, I thank you in advance!
