It's a new build. I only install DOS 6.22 on it and it has been stable. I'm running Memtest86+, just to make sure the RAM is fine. In order to replay quickly, I let it finished only one pass. But yeah, it's okay, no error whatsoever.Hmm, this is quite weird as it crashes when HWiNFO loads data into memory.. Could be something with the memory, is the system/memory stable?
