No post test on startup can not access bios - EliteGroup ECS A780GM-A Motherboard - AMD 780G, Socket AM2+, ATX, Audio, Video, HDMI, PCI Express 2.0, Gigabit

Try accessing the BIOS settings and set to a complete initial test (slower startup). If the computer turns off before completing the initial test (POST), then there is an hardware fault. In that case try starting the computer with no battery inside (only charger); try replacing memory modules; disassemble and start the computer with disc units and built in keyboard/pad not connected.

Hi,
For access the BIOS you need press the key F2 or F3 while startup.
Please try both the key one will work.

Thanks for using FixYa.

A BIOS (Basic Input/Output System) is an electronic set of instructions that a computer uses to successfully start operating. The BIOS is located on a chip inside of the computer and is designed in a way that protects it from disk failure.
A main function of the BIOS is to give instructions for the power-on self test (POST). This self test ensures that the computer has all of the necessary parts and functionality needed to successfully start itself, such as use of memory, a keyboard and other parts. If errors are detected during the test, the BIOS instructs the computer to give a code that reveals the problem. Error codes are typically a series of beeps heard shortly after startup.

It sounds like the Acer logo has been turned off in the bios settings. As soon as you hit the power button, start tapping the F2 key until you see the test appear "entering setup". Once you are in the BIOS, look for the Logo settings as far as being visible during Boot up. I've seen this setting on other systems so I am thinking the Acer should be similiar.

can you access bios screen (hold f10 during startup)? if so go there and test memory modules (run in test) and this also will test hdd. can you see any blinking/lit leds? then give me more info.

Try this press ESC, if this did not work press F1 or F2 lastly F8. Accessing the bios depend on manufacture. Process press the key and power if on the pc and keep pressing the key till hearing the beep or bios screen will turn on. Hope the info will help you access the bios screen.

Please go into the BIOS of the system and Set the BIOS as default

1. Restart your computer.
2. When the computer first starts, it performs the power-on self test (POST). This test checks that all connected devices are functioning. As part of the POST, the memory is checked. During the memory test, a message will appear that tells you how to access the BIOS. For example, you may see the following message or a similar message that explains how to start the BIOS setup: PRESS DEL TO ENTER SETUPIn this example, you must press the DEL key immediately after the memory test is finished to start the setup process. You may have to press the key several times to make sure that you access the BIOS setup.
   
   Tip There are other keys that may provide access to the BIOS. They include the following:
   • F1
   • F2
   • F10
   • CTRL+ENTER
   • ALT+ENTER
   • CTRL+ALT+ESC
   • CTRL+ALT+INSERT
   If you are not sure how to access the BIOS setup, see the user manual for your computer's motherboard.
3. Look for the Set BIOS as Default settings. You can usually use the arrow keys to move through the menus and settings.

Do that and then try to

The CRC error (POST = power on startup test) on boot up refers to the BIOS settings. This could be cause by a near flat BIOS battery and it needs to be replaces. If it is not the battery you need go to the BIOS to correct any faulty settings.

Welcome to FixYa! Delete is the BIOS setup key at POST. F12 is a one-time boot option. Safe mode is accessed by repeatedly pressing the F8 key at the first Windows splash screen. Post again if you have further questions. Steve
