I was set Greek Region Settings and I changed to English (USA) but the same results. I' m gonna use the same installations on windows 7 32 bit on the same PC to check if it's an operating system problem or my hardware and drivers. Thanks for your help.
The same results on WIndows 7 32 bit on the same laptop. When windows 7 loads a blue screen appears again and windows restarts.
This really sounds like either
a) a BIOS issue or
b) a corrupt installation media
As you tried the downloaded NI VISA installer only as well as the driver DVD, is assume that option b) is VERY unlikely.
I recommend to check with a totally different system. If that works correctly, you have pinpointed the issue to a hardware/BIOS issue on the specific computer.
