I have DP67BG mother board, my computer seems to load fine, but I see postcode 40.
Should i be worried ? What should I do to solve it?
I recently installed new hard drive.
You need to remember that POST codes are NOT error codes; they are simply indications that the BIOS has reached a specific milestone in its Power-On Self-Test (POST) processing. Sometimes, a BIOS engineer will add a temporary POST code to assist him with his debugging (range 40-4F is often used for that). In this case, the BIOS engineer simply neglected to remove the code before the BIOS was released into production. Bottom line, Doc is correct, you can ignore it. In general, it the system isn't hanging at a particular POST code, you can ignore it...
The below response provided by N. Scott Pearson contains the correct explanation for the post code.
As long as the PC works fine, you can ignore it.
Thank you very much for that information, N. Scott Pearson
