drvinst.exe runs automatically & eats 40% of CPU in Vista Home Pre

Media Player105
Hello all,

I have been having this problem in a couple of my builds w. Vista Home

Premium. For some reason, CPU usage is always in the 40% range. Using Task

Manager>Show all Processes, I find that drvinst.exe under

c:\windows\system32 is always running. Why is this happening? I can

manually terminate it, but it's a pain to do so everytime the system boots

up. I've already checked Device manager, and there are no

uninstalled/problematic devices with a question mark. Here are my builds:

Build 1:

AMD AM2 6000+

4GB DDR2-800 RAM

Highpoint RocketRAID 2310 RAID card w. 4x 250Gb drives

MSI K9N Platinum SLI Motherboard

MSI 8600GTS video card

Build 2:

AMD AM2 6000+

4GB DDR2-800 RAM

Highpoint RocketRAID 2340 RAID card w. 16x 320Gb drives

ASUS M2N32-SLI Deluxe Wireless Edition Motherboard

XFX 7950GT video card

I've used Highpoint RocketRAID cards before on other builds, and these are

the first two that I'm noticing this issue. Is it possibly due to the 4GB of

installed RAM (I know windows only recognizes 3GB or so).

Thanks in advance!

That file is often replaced by malware.... find ALL instances of it and

COMPARE them to each other and scan for virus and spyware.

Check the Registry to see where it is being called from :

Probably

HKLM\Software\Microsoft\Windows\CurrentVersion\RUN
