Good day! Sorry if repost.
I have MSI GX660 notebook pc (i7-720,10Gb RAM, 1250 Gb HDD); after installing (successful? ) BIOS update I have only blank screen and working fans.
What should I do in this case?
Thanks from Russia))

Did you do an EC reset?

>>Forum FAQ<<

How did you update? LiveUpdate? And more important WHY did you update?

Yes i did. I flash BIOS under DOS in Volkov Commander from USB flash. And Why: i have some problem, one of this it's not charging battery (yesterday it has been fully working, but today i don't have a battery power, think it is not battery issue), another problem - after restarting i have don't working any usb controllers(usb 2.0 and Renesas 3.0). In device manager i have this device with exclamation mark. I fix it by deleting this devices and updating configuration. After this all USB device working fine before next Power off/restarting. That's why I'd tried to update BIOS.
P.S. Sorry for bad English.

You didn't update the EC or forgot to reset the EC.
See forum FAQ as linked before.

Flash again if you can but: >>Use the MSI HQ Forum USB flasher<<
