Browser Crashes Lead To BSOD?

i've had this problem of google chrome at times crashing. once it does it that first time, it will continually crash if i try to open it about 3-4 times and then bsod my computer. it only happened once i think in january, and then went about 2-3 weeks without issue. recently, though, it started happening again. after the first crash of chrome nowadays, i get this weird 'right-click menu ghost,' where the first item i select after a right click will stay on my screen above any other window (but it will not do this if chrome hasn't crashed). i tried going around the issue and just use firefox instead, but firefox seems to be giving me weird flash-related crashes (i think). i'm not sure what is causing the chrome crashes, though. the same pages that crash firefox once will crash it again, but not always the case with chrome, so. firefox crashes also won't bsod my computer from what i notice.

i've run the memory diagnostic that windows 7 has and it doesn't seem to be a memory problem. i've done whatever spyware/malware/virus scans i know of (which, admittedly, isn't much) and it doesn't seem to come up with anything either. i'm at my limit of things i can try by myself...

edit: not sure if this has been the pattern the whole time, but the past two initial chrome crashes had an antecedent something like this:tab 1 contains a Internet video playing, and is the inactive tab. tab 2 contains an embedded (not sure if this part is relevant, but may as well add it) Internet video. i click on it to get it to start playing, and while it's loading, immediately switch back to tab 1 and pause my other video. chrome freezes and crashes, and from thereon will crash if you try to restore the tabs. if you start a new session, it will crash in a few minutes even without any Internet videos.
