Re: Hardware or game issue?
I tried that once before and still got the crashes, however this time I noticed that Guru DDU wasn't completely removing all the old AMD driver files. I manually cleaned them out and reinstalled 16.7.3. Played for about an hour and a half with no crashes before I left this morning, and played for about two hours tonight before my server went down, so it looks like that might have been the problem. I'll wait until I play more tomorrow before I mark solved, but things are looking good. Thanks for the input! Kicking myself for not noticing something so simple.
EDIT: Also, would love to know where you got the SWTOR avatar for this forum!
EDIT 2: Okay, got much farther along time-wise than last time, but still experienced a crash followed by a BSOD on relog tonight. Back to square one, I suppose.
