According to the spec sheet for Intel Pentium G3250 it is a Haswell generation CPU, which means you need a driver for 4th generation Intel Core processors. Intel HD Graphics 3000 is a 2nd generation Intel Core integrated GPU; in short you picked a wrong driver. Search for Intel HD Graphics 4400 or 4600. They are both 4th generation Core iGPUs so the results would point to the right drivers. Version 15.36 is for Windows 7 and 8.1 and 15.40 is for Windows 10. The 15.36 driver branch appears to have been discontinued though according to its front notice.
