If the problem is RAM/DIMM/MB then that will be ruled in or ruled out with the Memtest86+ testing.
If the RAM is malfunctioning > can use just one stick
Do you know if single or dual channel RAM?
If not download and install either CPU-Z or HWINFO
HWiNFO - Download
CPU-Z | Softwares | CPUID
If the memtest86+ rules out RAM then back to windows driver verifier to find other misbehaving drivers.
