9800/Direct3d issues

[Monkeyboy787]

OK here goes....

I'm running
AMD Athlon 64 3200+ newcastle
MSI Mainboard K8N Neo platinum (nVidia nForce3 250Gb chipset)
ATi Radeon 9800 pro 256MB
Antec 350 watt power supply

2 6 inch fans, plus I made sure my problem is NOT overheating by parking it next to a fan that got it so cold there was a teeny bit of condensation on the back of the box

I bought my system about a month ago, I had a K8T neo fisr, via chipset and had the standard ati//via interaction problems, fixed them up until yesterday by replacing that board.

After replacing the board everything worked fine, but then when I installed UT2k4 yesterday, my other direct3d games dont work (my only games i have installed are ut2k4, farcry, and doom3). Doom3 still runs flawlessly, but direct3d is downright broken, I immediately get either a black screen or a 'VPU Recover' message 3 - 4 seconds into gameplay, sometimes it doesnt even make it past the main menu in ut or farcry. I just ran a bajillion anti-spyware programs, I use mcaffe, and the system is perfectly stable as long as I dont play direct3d games. Also dxdiag detects nothing wrong--the diagnostics work just fine. I even got directx 9.0c, and still had no change. I really really really am trying to avoid a format/reinstall, because I have no guarantee that it will fix anything.

Does anybody know whats happening here? I'm totally lost and so is everyone else in my dorm

If you replace a mobo with a different mobo and you use any Windows OS, you must reinstall Windows. You are lucky that Doom3 isn't crashing.

ahh why do people think u can replace mobos and have the system still squeaky clean! there are SOOO many things that can be different on a new mobo, even if u update drivers and stuff, there old remanents of them are still there. if u just wanna test it out, use partition magic to create a new partition from the free space u currently have on ur computer. run winxp cd from ur desktop and install it on the new partition. u will get a messege to what partition u want to boot from when u first turn on ur computer, its a multi boot essentially with the same OS. on the new winxp u installed, do driver updates, fixes, service packs, DX ect. ect. then fire up ur games. if it works flawlessly, its ur OS. this process takes me bout 2-4 hours depending on the speed of the machine. but it safest way to make sure without having to backup\lose all ur precious data.
