I've recently started having pc crashes. When they first started, they would come randomly during gaming or web browsing, with a bsod and a windows stop error B3, physical memory dump. This would happen around once a day. Now it has escalated to crashing when loading up games, specifically Defiance. I purchased a 4gb set (2 sticks) of ram to upgrade with the other 4gb set I have already. I have tried re-seating the ram, and checked all cards and connections. I have re-installed my gpu drivers and checked temps on everything, which have checked out okay. Running cpu-z and checking all the DIMMs shows that all numbers match. Anyway, I'm not sure what to do at this point, and any help would be appreciated.
