I just bought an Abit V17 motherboard with a ddr400 512mb pc3200 stick. I am having problems with installing the game World of Warcraft so I talk to their tech support. They tell me to do a bunch of stuff and I do this all and the only thing that turns out bad is the memory tests. I downloaded a memory diagnostic tester from Microsoft and tried it out. 2 of the 11 tests failed. So, next i went to my friends house and tried the ram tests on them with my ram stick and all the tests passed fine. At this time it sounds like a motherboard problem so I call them. They say that it doesnt sound like a motherboard problem, but im not sure what else it could be so, they were no help. Hopefully someone here could help!
