I suffer the same Problem with two different machines now. All use AMD cards and CPU.
After sometime both screen goes either black or in single color and the machine isnt responding. Needs reset.
Use Prepaid Gametime codes... No double charges on account no nothing. You pay once and put the code. No recurring fees nothing. The most convinient thing ever.
Kudos to all that showed up in proper outfits (wich was the majority)
Boo to all those that didnt and showed up in their pink and neon green pajama outfits.
I really enjoyed the Event and cant wait to see more of thoose.
