I have been experiencing BSODs on my new computer. Have installed two different Graphics cards and two different mouse during attempts to solve this. Have run Memtest86 for 9 and a half hours, zero errors, as well as the MSMemoryDiag, zero errors. SeagateSea Tool comes up clean. Between installations of Graphic cards DriverCleaner removed all traces of the previous driver. Actually have tried several driver versions on the same card. DXDiag, no problems, HiJackThis, no problems, RootKit, no problems. BootVis shows only the explorer and Sygate firewall at startup. EWIDO, MSAntiSpyware, SpyBot and AdAware no problems Have attached a zip file of the last 5 MiniDumps. Can anyone shed some light on this problem?
