My environment is Vista Ultimate running on an Intel D975XBX2 motherboard
with an E6600 Core 2 Duo processor and 2GB of DDR2-PC6400 [800] memory; the
graphics card is an ATI Radeon X1950 Pro-512MB. The situation is that the
machine will freeze at different times [requiring a hard shutdown] most
noticeably when I have double clicked on something. At first I suspected my
Microsoft Desktop Elite mouse/keyboard for Bluetooth because the mouse would
move erratically at times. I eliminated the Bluetooth devices [and dongle]
and switched to a PS/2 keyboard and a USB wheel mouse.
At first the problem seemed to go away, but that was misleading; it has
returned with a vengeance. Just opening Outlook 2003 and clicking to open an
email can often trigger the freeze. I have now eliminated all USB devices by
installing a reliable PS/2 mouse. It has now been several hours without a
lock-up.
Yes, I have already installed the most current Intel BIOS and my Vista
installation is current with updates, including the reliability / performance
fixes released two weeks ago. Yes, I run an up-to-date CA A/V application as
well as CounterSpy, and have run several different online scans without any
malware being discovered.
I certainly suspect driver involvement, especially the USB drivers, but I am
uncertain how to proceed, or how to diagnose this problem any further. Any
help from the driver and/or Intel experts out there will be most greatly
appreciated.
Thanks in advance.
