Post the serial numbers of the DOA cards, and see if someone else gets it back from Newegg, still DOA?
If it happens once, good chance it happens alot.
Wondering if at the very least, Newegg is resending returns, to get 'second opinion', from second user. Then if second use says, its bad, send it back to the vendor. In any case, Newegg it sending out too many bad cards, to be automatically sending all returns to vender first, and then having a few of those vender refurbs fail. Not much excuse for artifacts to be showing up at, or just after boot up, on a vender refurb. Too hard to miss by tech. I doubt the 'tech' has even seen those 'lets get a second comsumer opinion' cards that get send back out, and indeed are factory rejects or cards the first customer hosed up.
