You will need to reinstall the OS once again as some files are lost. It is possible that some virus or malware has crept into the system software and moved files.

I just install 2.0GHz processor but my system keep giving 1801 microcode patch error, what do i do?


The 1801 error is defined as:
Missing or invalid Processor Microcode Patch.

Resolved by:
Applying a new ROM BIOS to support the processor stepping.

In other words, you need a BIOS upgrade. Contact your BIOS vendor and get support for your new processor.
