   Hi. After the BIOS update computer stopped works. On start I have beeps code - 2-4-3-2-4-3, after that computer reset and starts again beeps code - 2-4-3-2-4-3 and again and again (loop).

I have tryed to reset CMOS by jumper but it didn't do enything. Any idea how to fix this?

	I don't understand what you mean by 2-4-3-2-4-3. oo-oooo-ooo with o representing a single beep and - representing a pause? Could you record the beep code and upload it to youtube so we can hear it? Did the system say "Update Successful" when the update finished? Did the update actually complete or did the flash get interrupted somehow? If the flash did not complete correctly then you will need to contact ASRock Tech Support: https://event.asrock.com/tsd.asp

	I mean 2 short beep - pause - 4 short beep - pause - 3 short beep - pause - 2 short beep - pause - 4 short beep - pause - 3 short beep. Long pause (like restart computer) and again 2-4-3-2-4-3... does this description help? About "Update Successful" message - I don't know. After turning off Windows, the message "No HDMI signal" appears on monitor. I have wait a few minutes but nothing happened. After that I try restart computer but with no luck.

	Yes, that helps: The following are AMI BIOS Beep Codes that can occur. Beep Code Descriptions 1 short Memory refresh timer error. 2 short Parity error. 3 short Main memory read / write test error. 4 short System timer failure. 5 short Process error. 6 short Keyboard controller BAT test error. 7 short General exception error. 8 short Display memory error. 9 short ROM BIOS checksum error. 10 short CMOS shutdown Read/Write error. 11 short Cache Memory bad. So based on the codes you are getting it indicates a RAM issue (or a bad flash that effects the RAM). Follow the instructions here to fully clear CMOS: http://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal Then, when done, power the system on and leave it on for at least 10 mins. Let us know if this gets you up and running again. If not, you will need to contact ASRock's Tech Support department and inform them that you have had a bad BIOS flash and your board is no longer operational. They will talk you through what you need to do.

	I don't know. After turning off Windows, the message "No HDMI signal" appears on monitor. Looks like you flashed through Windoze, never a good idea. Likely the bios is corrupt as Xaltar states Contact Tech Support.

	The first (and definitely the last) time I used the Windows update. I have contacted the seller, but it turned out that the mobo has a seller warranty (24 months) and they do not respect the manufacturer's warranty (36 months). Looks like I need to buy a new mobo :(
