You change the jumper like it says, put it back, and then turn your computer on. Step 6 probably means to enter the BIOS and change the settings like you need to. What I would do is to leave the manufacturer's defaults alone right now to see if it works because the problem could have been in your settings.

Please answer the question.

sorry for late reply.I mean I unplugged all the wires which connected to cpu,like usb,power plug,...
I'm still facing the problem now,I've taken a lot of time to seek what's the real problem is, and now even I reset BIOS setting, that 1+3beep sounds still happened.
Should I update my BIOS? Is this ASUS problem or my pc problem?

Thanks again.

I wonder how can you turn off the CPU using the Alt+F4, these 2 keys are for closing the current active windows/app.

For beep sound and hang OS, try the following:

check all CPU and video card fan, make sure both working correctly.

Reseat the video card and RAM, use other RAM slot or just 1 RAM or other known good ram to test the system.

From the windows RUN option, type "msconfig" and press enter, from the pop up startup option, disable all options and reboot PC. If the PC works, you can select the option back, those common options like IME, Antivirus app should be ok, some unknown program startup option, just not to select them, or select them 1 by 1 and must reboot PC for every option you select to take effect. I believed this is going to take you time since you need to wait 7 hours for every option you select. Hope there is no scheduled task causing you the problem.
Or you can back up data, reinstall the new OS to eliminate the software concern.

Hope this helps!

@ Bill thanks for trying to help but a program conflict is not going to cause a BIOS beep code. That is an indication of a hardware problem. One problem at a time.

Let me make sure I go this correct: do you mean that you get 1 continuous [long] beep followed by 3 short beeps? If that is the case you have a problem with the BIOS detecting your graphics card. Do you have any video? Do you have access to a spare graphics card that you know works? If so please try that card in your computer. Do you have access to a desktop computer, that you know is good, with a PCI express slot? If so please test your card in that. Also you can try to plug your graphics card into the slot beneath where it normally goes.

Could you be confusing the 1+3 with a 1+2? If so then you have a memory issue.
