Speccy (very similar to Ksenom_O) on Samsung RV510:
Manufacturer Intel
Model Mobile Intel 4 Series Express Chipset Family
Revision A
Subvendor Samsung (144D)
Driver version 8.15.10.1892
Exact same symptoms with an elderly Samsung RV510 (W10-64 bit). Gone back to 5.55 for now but will need to look elsewhere at some point. This machine also has Intel Graphics (4 Series Express)
Various other W10 64 bit machines are OK.
