I have several problems with my new computer. I have uninstalled Avast and Firebug (plugin to Firefox) but it did not help.. I sure would like to have Firebug installed but that would not work?
Your memory is set well in the bios. That means it is defective.
Use Memtest86+ to test overnight 8-10 passes. When errors show, then you can go ahead and replace the memory with new. Or try to return the current ones to the company for free replacement.
