Please download and run Live Linux
Just don't install it. You can boot from the CD/USB you create with the ISO and use them just to try them out. They run out of ram and can be used to tell if it is a hardware problem or a Driver/Program problem. The OS installed is not loaded and not used, so it takes that out of the equation.
Shortly, a last test for the memory.
A read error with the memory
Probably caused by : memory_corruption
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arg1: fffff6bf7e253748, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff8004e4e5a42, address which referenced memory
