Hello all.This is my first post here. I do hope this topic hasn't been discussed before, been roaming here and there, yet haven't got specific answer. well, as it is written on the title, I had this blue screen crash quite often, it has been getting worse. I'm not sure what caused it but it is stated that the error was:DRIVER_IRQL_NOT_LESS_OR_EQUAL*****viahduaa.sys - address B2d9A25F base at B2d5A000.Been browsing for days collecting info, most of the forums suggest that I had to do something with the VIA Audio Driver, it makes sense since the message is apparent in the blue screen, but some of them came up with checking the RAM, PSU even Mobo, and an anti virus software developer wrote this introduction to its product that it could be some kind of virus. So anyone who knows about this or has similar experience can please confirm that it is simply my VIA Audio driver? I have removed the driver (even re-installing window) and I have installed sound card separated from the mobo.AMD x2 250 3.0 Dual CoreMSI (oops sorry, forgot)RAM 4GB DDR3 G-SkillGeforce 9800GT 1GB - 256 bitHD 500GB SataThank you in advance. :)Wisnu

Google is full of pages with folks reporting BSODs caused by viahduaa.sys.Recommend you visit the VIA Drivers Update page and update your viahduaa.sys.Cheers,- jahman.
