New CPU problem

[MonkeyWrench4000]

I recently updated a Intel 865G board from a 2.4ghz celeron to a 2.8ghz p4 prescott.

The rest of the components:

WD 60gig HD 7200RPM
Radeon 9800 PRO 128mb (ati official)
1024 GEIL DDR400 in Dual channel


After I updated the cpu, my video games have become very jumpy. In games like Doom 3, HL2, and Guild Wars. Even when I am running at 50fps, i still get this jumping that looks like lag on a MP game. Its most aparent when running in a First person shooter, starring straight at the floor. Normally this motion would be smooth, but now i have periodic jumps. This has gotten so bad in CS source that I cannot even play the game.

I have tried the following:

More powerful PSU (a 450w max)
Reinstall all games effected (including manuyally deleting leftovers from games like cfg files)
Reinstall video card drivers
Remove all spyware and virus's
Check CPU temps
Check for CPU throttling
Changed memory configurations (what slots, single or dual mode)
Running games with the computer case side off


Additionally, I have also verrified that this mainboard does support all the hardware I am currently running.

I cannot check my video card temps, but the heatsink is very hot to the touch, it doesnt burn, but it gives your finger the sensation that it is going to, so it has to be close. It's even this hot with the side off. Other 9800pro owners have stated this is normal.
Plus, the 9800pro was fine with the old CPU, the celeron, so it couldnt really be that.

Any help would be great. DxDiag says Dx9c is perfectly fine, but should I try reinstalling it? What else should be done after a major hardware upgrade? My 3dmark03 score is not effected by this problem as it doesnt actually lower frame rates in any way. How does that make sense? Could it be the monitor??

Can someone who knows about a problem like this seriously consider what it may be.

Thanks for all your help in advance.

Makes no sense to me. If your board supports the Prescott, I would think you could swap from the celeron without changing a thing and never notice. Only thing that pops to mind is that if you reset the CMOS, maybe it turned on the 865G's onboard vid option. This assumes you had it off before as well as assuming having it on would even cause a problem which I don't think it would. Have you tried going back to the Celeron to see if the prob goes away?

No, I havent tried going back to the celeron yet. I really was hoping i didnt have to, im fresh outa thermal compound/grease.

Do you think it could be a registry problem?

Im seriously out of ideas. Its killing me.

Maybe try loading optimized defaults in the BIOS, then do a Windows repair. That should fix any registry problems, and set everything back to normal. Doing a "repair" will keep everything else installed, so no need to reinstall everything again.

Wil i have to reinstall SP2 or will it keep all my current updates as well?

If you window cd doesn't have SP2 then it will loose the service pack and updates, and you'll have to re-install them, but all of your other programs and files will remain intact. Could you be more specific about what motherboard you are using? Did you enable hyperthreading in the BIOS after installing the new CPU? What specific power supplies have you used? I ran a 2.8 prescott at 3.5ghz fine on a 350w enermax, which I would trust far more than a 450 generic PSU.

I have found the solution.

Although I have repeatively re-installed my drivers for my 9800pro, I never tried OLDER ones. I went and tried out the 4.12 catalysts, which are two driver versions back from the current one. Not only did it entirely get rid of this problem, but my performance increased. (these drivers were geared for the 9000 series)

For the record my friend was having a problem properly displaying the textures in HL2/CSS while in high quality mode with his 9600pro. After replacing the newest drivers with the 4.12, his problem has also been fixed. The new ATI drivers are horrible for the 9000 series.

Thanks for everyones help!
