Hi all.
Misteretc, can you try this from the command prompt?
"%programfiles(x86)%\Google\Chrome\Application\chrome.exe" --disable-extensions --disable-plugins
This will make Chrome open in a safe boot, no addons or anything, bare minimum support. Monitor the performance from there and see how it goes, if you notice a difference from safe boot to normal mode, then something different is installed, a rogue addon possibly.
From there, you'd have to identify what add-ons are installed, remove anything you don't need/want, or a secondary alternative, backup any favourite links (export them if needed) and delete the Chrome profile. This will force a new profile, basically a factory restore within Chrome, everything will go back to default like it was fresh install.
