If you have ram problems those bsods can point at almost anything so may be meaningless. If it does not help to uninstall then install Nvidia drivers try exclude ram by running Memtest86 http://www.memtest.org/
Ram could be ok even with errors, problem is bios settings, voltage/timings. Or a fan stopped spinning and overheating is causing bsod. Power supply might be over the hill, motherboard the same. A cable, video card, ram module could be lose. Kicking it about might fix everything. Try focus on hardware first. Then software if not something is obvious. Be careful not to follow hints from bsods or even minidumps automatically because if hardware is problem they will say go west, now east, now remove Windows. Windows cant diagnose hw problems that well. Those bsods you have are typical for hw problem - messed up video drivers are a force to be scared of, but they are typical.
When excluding dont hold back on taking out cables not absolutely needed. Stuff like printer, scanner, anything usb. Until you know cure, be suspicious of anything. The less you have attached/actively running the easier task is.
I looked at your other thread. Well I dont know about obvious but damn that is a long log. "Driverscan" program to help get you right drivers? Hmm, like using a rouge scanner for safety to me ;) You can find nvidia.com yourself I think. vtany.sys? wonder what that is. Well after you are pretty sure hardware is ok try exclude software. Could be a weird conflict, punkbuster vs. something.
It said "c:\memtest" in one of the logs. That is from their guide to run Memtest86 right? Well did you ever complete test?
