msi motherboard checksum error?

Answer 1

That is not even a sentence.

It sounds like a CMOS checksum error. If you have recently reset the cmos then that is normal. if your cmos battery is no longer working you are going to get a Checksum error everytime the pc starts up. Open the case remove the battery and go to a pc store or watch shop and get a replacement. that is if the battery can be removed. It's that round silver thing you see on the motherboard. after you replace it with a working battery it should be fine again.

that is the best answer you are going to get with just 4 keywords. Next time ask a question with more details.
