I have an ASUS model X83V and my screen has been flickering (not in brightness, but actually going fuzzy and "jumping"). The flicker can take upwards of 1 hour or more before it goes away, but usually...
my son has this same machine and after a year of almost daily use it developed this same flicker you describe, about every 4 secs, then it got much worse, almost like an old tv rolling. i took it all apart and inspected it all. didn't see anything really troubling.
yesterday it worked fine all day while i installed a bunch of updates for another problem. i left it on all night doing some other things. this morn when i got up it was still ok. then after a while it started in again, every 4 secs.
so i've been troubleshooting the damn thing all evening and have come to the conclusion its from over heating, probably cause of the crappy heat sink connection. i noticed if i take it outside in 40 degree weather and leave it a couple mins on the hood of my truck, it goes away. bring it back in and after 5 mins it comes back. take it back out and its fine again in a few mins. also, yesterday my house as much cooler. my fire was out and it was in the upper 60's in here, today as soon as it got to 76 in here, and it was above that all day, it started acting up
so i think my next step will be to try and make a better union between the chips and the heat sink itself. you should try a test with yours. start it up, make sure its flickering, put it in a cold space for a few mins. just be caustious of condensation.
