Shortly after booting up, my asus notebook emits a piercing alarm type sound which can only be stoped by removing all sources of power. g73jw series. what can i do to prevent this

Dont shut it down! Buy a new laptop!

or, more practically, have a look in BIOS setting and see if you can turn off the on-board screamer (Prob doesn't go by that name), also check that no keys are stuck down when the power plug is in!

Step 1.

Click the Windows Start icon, and in the "Search Programs and Files" field type regedit
Step 2.

Navigate to the following folder:

HKEY_LOCAL_MACHINE \
SYSTEM \
CurrentControlSet \
Control \
Power \
PowerSettings \
54533251-82be-4824-96c1-47b60b740d00 \
5d76a2ca-e8c0-402f-a133-2158492d58ad

Step 3.

Click on ATTRIBUTES

Step 4.

On the top of the dialog box it should say DWORD

Step 5.

Change the 1 to a 0

Step 6.

Click on the Windows Start icon.

Go to Control Panel -->

POWER OPTIONS -->

Advance Power Settings -->

Processor Power Management -->

Processor Idle Disable

Set both of them to Disable Idle.

I have seen this behavior when a key is stuck in the down position. While the laptop is off, press down each key, one by one, and ensure that the key is returning to its resting position. If a key is sticky, press and release it a few times to try to free the key up.

Power on the laptop and see if the beeping stops. If you can tolerate the beeps, let the laptop run for a few moments to see if an error message appears. If you see a keyboard error, then you can try working the keys again.

If there has been some sort of liquid spilled on the keyboard, it may need to be replaced.

I would try reseating the RAM (memory).

Consult ASUS's website for instructions on exactly how to remove the RAM, but usually there's a little panel on the underside of your laptop with one or two screws, remove it & look for the RAM. Pull it out, wait 20 seconds or so, put it in, reboot. See if that helps.
