    OK I've encountered two times that these screen flickering / momentarily blackout issue since I got the new i7 iMac

    but I would say it happens quite rarely and is easily resolved by a reboot

    Just now I opened up the TechTool Deluxe that came with AppleCare and ran it, and the VRAM test failed, even tho I am not having the flickering issue for now

    it didn't say the reason tho...any of you have the same results? :rolleyes:

    Before you wig out run an apple hardware test from your gray restore discs and keep in mind that while tech tool is highly useful, there is a small (very small) chance that it is not yet recognizing your i7's components. I know that is wacky but weirder things have happened.

    I agree with jessica.. It may be that the hardware just isn't recognized.
