hi again,
first of all thanks for the help and suggestions, Kemical and zvit.

yes i would say the flashes are very quick, the screen is black for about 1 second or less and then back to the logon screen, then it repeats.
Even though I have the newest graphic drivers installed, I reinstalled them after reading your comment...just in case. I always do it via Control Panel and then uninstall the program, I am not sure if this way deletes all the files and data of the program. However when I uninstalled my Nvidia driver, my notebook was faster after the reboot/restart for some reason. Windows claimed it has "installed new drivers" but when I checked the control panel I could not see the Nvidia drives or anything that has to do with Nvidia. So I proceeded as usual and installed the drivers manually and after this reboot my notebook was slower than before. It took 10 seconds, if not longer to boot and windows itself felt slower. I didnt expect that. Nevertheless the flashes are gone at the logon screen but now it takes longer to boot up. I would have never thought a reinstall would fix these flashes. Oh by the way I uninstalled all that Asus stuff you get with the notebook as well (I dont know, it might have something to do with the flashes).
Thanks again for the simple but yet effective advice.

well I am planning on using my monitor since my notebook screen has only 14inch but I havent used my monitor yet. But there have been tons of errors, the majority of them are:
"Activiation context generation failed for "C:\Windows\system\S6000Dex.dll". Dependent Assembly"
