checksum error

[Olin Lamanna]

I just want to share my experience if ever you experience checksum error and system restore didn't help, you can try removing the battery and memory of your pc, its like a reset and just put it back.

The simple checksums described above fail to detect some common errors that affect many bits at once, such as changing the order of data words, or inserting or deleting words with all bits set to zero.
