Screen flicker in high res games

[Entragian ][]

Athlon600 (650 core) o/c at 800MHz
384Megs PC133 Micron
Asus K7V 1006Bios (set 4:3 for memory)
SBLive

I upgraded from PC100 to PC133 memory sticks. They are both Micron (128 & 256) Since then, my screen flickers every now and then when playing UT and Tribes. I get a line that appears and vanishes in an instant. I am lead to believe it is my memory, but I put the PC100 back in and it still does it.
I am running DirectX7.0a, Detonator3 and all other current drivers.
When playing Soldier of fortune or Quake3 the screen does NOT flicker. Could it be D3D?
All answers appreciated. Its playable. It is just annoying after a while..

Do you have a Gforce card with the 618 drivers?
On mine it has done that but not to the extent that you seem to have, I get a thin white line zapping across my screen when loading Dues Ex but does not do it in any games.
532 drivers did not do it.

I have had the Deonator3 drivers in for quite a while. Its possible that they are to blame, but it didn't occur right away.
I might try and install older drivers. Test some games, then the Det3's again.

time consuming.

Detonator3 drivers are the cause of the game flickers. I uninstalled them and then reinstalled the origional Geforce2 drivers. The game runs without any problems. It looks like I will have to hit Detonator2 drivers until I can figure out if there is a way to get the Det3's to work.
****, the performance boost with the Det3's was very noticable too.
Worked for a while and then poof. All of a sudden problems.

Any suggestions will help.

Thats really strange, I have the same mobo and a geforce2 and have not had that problem, did you try reinstalling the via drivers maybe?
