Alright, I recently upgraded my computer with a new motherboard (Gigabyte GA-6OXT), another stick of RAM (infenion 256mb pc133), a new case (antec 300-watt mid-tower), a WD 80gig 7200rpm HDD, and a few case fans and rounded IDE cables. The rest of my system is a P3 933mhz, 256megs PNY pc133 ram (512 total), GeForce4 Mx420, SB Live 5.1, and a Maxtor 40gig 5400rpm HDD. Anyway, ever since I installed the new parts and reinstalled WinXP (I use XP Pro), I am noticing a weird problem with my games. The first time I run a game (mainly Counter-Strike or Quake3), it runs perfectly, but if I close the game a try to play again, I get MAD choppiness, even though the game is saying I'm getting 100 or so FPS. At first I thought it was a crappy stick of RAM, so I took the new one out and the problem seemed to go away, but taking the new stick out only slowed the time before the choppiness kicked in (it happened on the 3rd opening of the game). Then I used the new stick by itself, and the same happened when I had the old stick in by itself, which led me to believe the motherboard had faulty RAM slots. I don't know though, if anyone could help it would be much appreciated, I don't have forever to RMA this stuff.
