    Hi guys -

    I have totally run out of steam on this one. I have a two year old XPS M1330 with a weird problem.

    Running Windows Vista Home Premium (originally shipped OS), Task Manager showed the CPU as at or near 100% all the time. Notably, Task Manager itself was using ~40% of the CPU all the time.

    I nuked the thing, and installed Windows 7 Home Premium. Installed a couple drivers (Ricoh, Nvidia), patched the OS. Task Manager STILL shows the CPU as at or near 100% all the time. Task Manager itself still using ~40% of the CPU all the time.

    Between the two OSs I did update the BIOS to the latest - I think A15.

    I have three M1330s in a similar configuration, and this is the only one that exhibits this behavior. I'm assuming it's a hardware device since all three were installed using the same set of drivers. Now that I'm talking about it, the only device I'm not positive about is the wireless - they may be using different wireless cards. I'll have to check on that one.

    Has anyone ever seen this before?

    ...and I answered my own question. Removing the wireless card fixes the issue. It's a Dell 1395 card. Guess it died!
