Network Connectivity Causing Lock-Up

[Shabach]

Lately when playing warframe, I'll be in the middle of a mission and the game will lock up and become completely unresponsive. I just recently noticed this usually coincides with a suddenly poor connection, which might be a problem with my service provider, or the router/modem. 

I just recently did some registry repair via CCleaner, and didn't experience any more issues the rest of the night, though the problem is infrequent enough, that might just be coincidence.

I just wanted to post this here, if anyone else is having similar issues, and can also correlate network connectivity to the crashes.

P.S. The game doesn't actually crash, the display just freezes. I can still hear game sounds playing, and controls also work (I can hear the menu open and close, and can hear the selection of menu options). It just occurs to me I might be experiencing graphics card issues, as in a faulty card. I'll explore that on my own tonight.

Happened last night again, in the middle of a void mission. :| Getting really frustrating, I'm losing a lot of potential argon.
