I'm on Asus running vista. Ran memory diagnosis once but found no problems and I can't turn it off ever since, except to use "Esc" each time at start up. Anyone has any clue how to disable this and let me enjoy the Asus as it was before the stupid test? I have tried system restore to no avail.

Try describing your problem to further detail. What you're saying sounds like something on a bios level or even a corrupt install of windows or something.

I'm using and ASUS laptop and so far apart from the usual windows hickups i've not had any problems with it o.o
