So yeah, my PC has been behaving strangely the last week or so. Browser would just close out of nowhere, the game I play (BDO) would also do that, or give me a "corrupted file" error that clearly has nothing to do with a corrupted file. Both applications can go on for hours without any issues though. I've also had three BCCode 1a BSODs, so I finally ran Memtest last night and while most loops go without errors, on occasion it will find one at a specific memory address and keep getting the same one, until I restart the test. It is a different address every time though. It's somewhat similar to the "corrupted file" issues of BDO where if I keep trying to load the character/area I've first gotten the error at, the game will keep crashing, but if I load a different one then there's usually no problem. My question is can these problems be caused by something else other than the DRAM chips? I find it hard to believe they suddenly developed "bad sectors", and I'm more inclined to think it's the CPU memory controller (it's the oldest part by far and runs very hot these days, cause it's a 40+C heat where I'm for the summer). How can I test for that?
