I ran Windows Update and it require me to restart my PC, so I restarted. I turn on my PC 24/7, I don’t shut down but only goes into sleep when I am not running anything in the background. Back to after restarting my PC, my PC surprisingly hang at the bios, the activity light on the CPU was not blinking and it just stuck there. Nothing I can do. Can’t access the boot menu, bios setup or anything which is bios screen related.

It’s probably not the software problem because nothing will mess with the on board flash setting. So it’s most probably is the hardware problem. But why it hang after restart but not during the PC was running. Don’t understand.

After Googling and know about it’s the hardware problem. I remove my RAM, my GPU and my Linksys Wireless N PCI card and replug it in again. In the end, my computer is running smoothly again and no more bios hang. Still got no idea why it happened. Any idea?
