Problems with drivers.

[AsAsIn8eR]

I just bought a couple of days ago a videocard.An asus en7300gt top with ddr3 memory.I installed the drivers that came with the board and everything seemed ok until I ran a 3dmark 2001 where I got 7000 3dmarks this seemed.I thought it was my windows so I reinstalled it but when I did it had the same problem the same score.Then I opened accidentaly the task manager to restart and I saw that the CPU usage was at 80% in idle and that I didn't have any procces running with this usage.I reinstalled again thinking I did something wrrong and before I installed the video driver(I installed the motherboard driver(DFI Infinity UltraII M2) and it was 0% and right after I installed the video one I got 80%(after reboot).I tried the latest Big_Sam's moded driver too with it I get 50% usage.I tried the lates from nvidia I tried 92.91.All of these give em the same usage.What can I do?What could be the problem?The videocard uses IRQ 18

Well..... Since no one else has, I'll take a shot at this problem....

AsAsIn8eR,

I'm not an expert at these type things but I did spend the night at a Holiday Inn Express once (American joke - if you don't get it, don't worry about it). Usually, when problems like this crop up there are some left over driver bits hanging around on the computer. Download new drivers but don't install them (save to desktop). Download Driver Cleaner Pro if you don't already have it. Clean up / delete everything on your computer that you don't need... I'm going out on a limb here and assuming that you're running XP. If you are running XP, turn off system restore, delete cookies and history and run a virus scan. Run Disk Cleanup (wouldn't hurt to do a disk defrag at this point). Un-install the current drivers (for your video card). Reboot into safe mode and run Driver Cleaner Pro. Reboot, turn on system restore (if you normally run with it on), then install video card drivers following nVidia's instructions.

Let us know if this works.

I already tried that and it didn't work.There were some things that gave me the false impression that they worked.I disabled write caching and the CPU usage was gone for a while but then it came right back.Does anyone know what is that write combining option?
