As per the title. Had some hard lockup errors so I decided to update the Bios to see if that helped. Went from factory default to 3401. I downloaded the most recent file from Asus website, ran their installer thing that changed the file name. Opened the BIOS menu, selected the file to update. It took a few minutes and then reset. Upon resetting it just runs the CPU fan. No monitor out, or anything... Did I mess something up?

**Update** I gave it 10 minutes, restarted the PC via PSU switch. Booted it back up and it worked! I guess it just got hung up on the reset. It rebooted many times after, with scary red lights coming on. However that just seemed to be DRAM, VRAM and CPU tests. It then booted to the default "Please enter BIOS setup" and then I saved and exited. It rebooted again, and loaded up no problems. WHEW.
