My gaming rig is freaking out.

I added my Toshiba hard drive after an RMA and a few days later my system just started bogging down really bad. After a couple reboots iot just would freeze up. I then removed the hard drive completely and it sped right back up.

Now everything is freaking out.

I try to run iTunes and it starts up, but before I can select a song it reports iTunes has stopped working. But no other error messages.

I tried uninstalling iTunes and rebooting to run ccleaner to clean out any config files left behind, but I still get the same error message.

I then bring up Norton's for a scan and select liveupdate to make sure everything is up to date, but it won't download the update and errors out. It will scan though and reports nothing is wrong.

I have malwarebytes and it reports nothing as well.

I went through the Malware guide here and here are my logs and hopefully someone can give me a clue as to what's going on with my system.

Also, my chrome browser loses the toolbar, except for the main Google home page. Once I leave that page the toolbar vanishes.

Thanks
