BAD_POOL_CALLER?

I had connected a faulty keyboard and mouse for testing purpose . This has corrupted a log file from System.log . If i try to install or repair i get the Blue Screen with BAD_POOL_CALLER error

What a load of rubbish, you won't need to replace your motherboard. Note the error messages and look online for a fix. Worst case scenario is re-loading your operating system.
