I have a G74SX and I updated the BIOS to the current version (BIOS 203). The update was done through the BIOS screen and was successful. Rebooted it and now it turns on then instantly back off! any suggestions would be great. Tried the Control+Home+Power combination and that doesn't work.

How did you go about flashing your bios? Did you use a usb flash drive formatted to fat32 or did you flash from the hdd?

Through the actual bios. I put the bios update on a USB key the updated by going into the bios and updating.
That is how i update my computers bios

If this was happening to me I would try a hard reset.

Take out the battery and hold down the power button for 30 seconds. Power on the laptop with just the adapter.

If that doesn't work you can try to remove the cmos battery (you have to take apart the laptop to get to it) and do a hard reset.

If all else fails your best bet is spi flash reprogramming.

I have a G74SX and I updated the BIOS to the current version (BIOS 203) downloaded from ASUS. The update was done through the BIOS screen
and was successful. Went to Reboot it and now it won't even power on. Any suggestions would be great. I had used the easy bios flash in the bios and located the file stored on the HDD
What if anything can I do to get it back??? Thanks
