@Amar_chaurasiya -- error message like the MCH is operating with ddr2 667/cl5 in single channel mode problem.

That is not an "error" message. It is an "informational" message.

If there is only ONE stick of RAM connected to the motherboard, you get this message.

If there is MORE than one stick of RAM, then one of the sticks is not working (or is not fully "seated" in its socket).

If there is MORE than one stick of RAM, and one stick is DDR2/667, and the other stick is NOT DDR2/667, then "dual-channel-mode" cannot be used. The motherboard uses "single-channel" mode.

Does your computer usually show more messages, such as the list of detected devices, such as keyboard & mouse & CD/DVD & disk-drive?  If not, then your motherboard (produced in 2007) is failing. If it is failing, it's time to buy a new computer, in October 2021, or later, that runs Windows 11.

Note that MIcrosoft's support for Windows 7 ended in January 2020. That is another reason to get a new computer.
