    UAC crashing explorer.exe


    I got this 2-3 month old Lenovo laptop, win 7 x64 home premium. I log in as standard user. i have UAC set to Do not Dim. maybe 60% of the time after UAC prompt pops up and I enter password to allow, explorer.exe would crash.

    I did Memtest86+ for about 4 passes , nothing came up. I did sfc /scannow , nothing came up.
    I did clean boot, which avast AV and 2 lenovo process still ran, crashing still happens. I also used ShellExView to disable all shell extensions in normal boot, doesnt help.

    I attached a dump that I did using task manager->right click explorer.exe->Create Dump File-> !analyze -v using winDbg.
