Help! I got the USB Desktop Microphone based on glowing reviews. When I plug it into my Windows 7 system (64 bit Ultimate) it was a bit balky getting drivers installed (took two tries) but after that it worked fine. However, the next time I rebooted Windows 7, it crashed with a blue screen during boot. Even worse, after the crash, the next attempt at rebooting goes slow or hangs in the BIOS POST screens.
Dropping back to a restore point before I installed the mic, or unplugging the mic allows the system to boot.
Not exactly the experience I was expecting from a fairly basic product.
Anyone else seeing this?

The USB mic works on all the computers I've tried, even the one with problems. Crashes only happen upon reboot, and so far only on that one computer. Here's a comparison of the problem computer and an OK one:
OK computer: plug in USB mic for the first time, it immediately loads two driver (USB Composite and USB Audio) presumably from the local install, because it happens fast. After that, everything just works. And, no reboot crashes. OS is Win7 Enterprise RTM 64 bit. This system is an HP Elitebook 8530w.
Faulty computer: plug in USB mic USB Composite driver loads immediately, 'unknown' device goes to Windows update to get drivers, and fails. Unplug and replug USB Mic and then the USB Audio driver installs. Drivers installed are the exact same as the OK computer (dmk.sys, ksthunk.sys, portcls.sys, USBAUDIO.sys, SysFxUI.dll, WMALFXGFXDSP.dll, all Win7 RTM versions). After that, the mic works. But if I reboot this system, it crashes with a PAGE_FAULT_IN_NONPAGED_AREA during the reboot, if the mic is plugged in. I've further narrowed it down to where the crash only seems to happen if I plug into the USB hub built into my HP w2207h monitor. Also sometimes I get a "device cannot start" when plugging the mic in there. OS is Win7 Ultimate RTM 64 bit. The system is home built using Gigabyte GA-MA69S2H-G4 main board. I don't get crashes if I plug directly into the mboard USB ports, though I haven't tried this very much yet.
