So, recently upgraded to 2GB of ram from 1GB. Its OCZ, good quality stuff. Timing settings are good, ran several burns and overnight mem tests, memory tests OK. Random BSOD's are happening. Can't replicate, randomly happen. Sometimes they reference tcpip.sys, other times nothing but an address number. SO I did a full uninstall of all nvidia drivers, a driver clean, then a clean reinstall of drivers straight from nvidias site. Still having BSOD's, but so far only referencing an address. This is the latest error message from the event viewer: Error code 1000007f, parameter1 00000008, parameter2 80042000, parameter3 00000000, parameter4 00000000.
