This morning my computer went to the post screen and stopped. I tried again, several times, same thing. No response to keyboard prompts, no bios, nothing. Tried waiting it out, but five minutes was my limit. Then I began pulling out USB devices. Started with the new HP cheapo printer. Then took out an external hard drive. Then I got a normal start. I haven't reformatted in 18 months and am thinking about going to Win 10. This is a good machine for my needs, and has lasted six years with reformats every year or so. Any thoughts? BTW yesterday I went into my BIOS but made no changes. I don't know if that has anything to do with anything but it's a fact. Thanks, amigos~
