when I try to launch HWinfo64, it crashes during startup, right around the CPU bus detection.
Sys-spec:
Windows 7, 64 bit pro.
16 gigs mushkin RAM
R9 390
AMD 8320 @ 4800mhz
mushkin reactor 512gb SSD
Toshiba 2 tb Hdd
WD blue 1tb Hdd
This seems to be caused by some USB device or controller - when HWiNFO attempts to query its state the USB protocol causes a crash.
Please try to detach USB devices to see if that might help. Alternatively you might try to upgrade USB Host Controller drivers if possible or disable controllers not used.
