I bought a new CPU for my Intel DG41TY and installed it. It works, yet there is a couple pf problems. The first is that a couple of insructions don't work. SSE4.1 and Intel VT-x and it cant restart. For restart I must shut down PC first and then turn it on again. Many people are had the same problem, they just modded their BIOS updating the microcodes section. I can't do it because of security against uncertified BIOS files.
P.S. I have the latest BIOS for my m/b, it is TYG4110H.86A.0045.2010.0706.1910 dating 07/06/2010, Yet the microcodes there are from 2008.
