I came home from work today to notice that my monitor was off. I use the onboard video, so I verified the computer was on and connectoed properly still. I originally thought that my monitor went out. So I decided to bring my computer in to my living room to connect it to my tv. After connecting to TV and getting same result, (No picture at all) I opened up the computer case and noticed 3 red led lights (Led Lights PH1, PH3, and LED 2) After checking witht the manual, I have come the learn that when LED light 1 is off and LED light 2 is on, it is a VGA ERROR. I do not have a video card to check. Does anyone know anything I can try to get this resolved?

Hello and welcome to Bleepingcomputer.

First off here is a support link to BIOSTAR for your computer.


I read through your owners manual and seen the LEDs you are referring to.

Do you hear any BIOS beep codes besides the normal one BEEP during post?

Your manual mentions those POST error codes on page 34 Section 5.3 AMI BIOS BEEP CODES.

POST BIOS Beep Codes

Number of Beeps---Description of beep codes

1-----------------Memory refresh timer error
3-----------------Base memory read/write test error
6-----------------Keyboard controller BAT command failed
7-----------------General exception error (processor exception interrupt error)
8-----------------Display memory error (system video adapter)

If you were experiencing an error with your on-board graphics accelerator there should be 8 beeps.

I want to stress that your motherboard uses the RAM you have installed for video memory, if for any reason one of those RAM sticks is acting up, you may not have any video display.

I suggest you try re-seating your RAM sticks in their slots and try booting the system again.

Another method you could try if re-seating the RAM does not fix the problem is to try resetting the motherboard.
You have a reset button on the motherboard, try pressing that and see if that does not fix the problem.

If you happen to have a DVI to VGA adapter handy you could try using the on-board DVI port, this will tell you if your on-board VGA port has a faulty solder connection to the motherboard.

Another re-set option available to you is the CLR-CMOS jumper which is just to the left of your CMOS battery holder. PLEASE REMOVE THE BATTERY BEFORE DOING THIS!!! Move the jumper over from pins 1 and 2 to pins 2 and 3 for 30 seconds. Move the jumper back to pins 1 and 2 and return the battery back to its holder.

Try booting the PC and When starting up the computer, press
<Del> during the Power-On Self-Test(POST) to enter the BIOS setup utility.

If you still have no video, please let me know, however if you do, and you did clear the CMOS, you will have to correct the time and date and make sure all hard drives are actively showing in the BIOS screen, once changes have been made, please save those changes by pressing F-10 and choose YES and exit.

You should also go to your support link above and look under the MANUALS tab and download that file, it contains both a user manual and the BIOS setup utility instruction manual in the same .zip file.

Best of luck to you and keep me updated with your progress. :thumbup2:

Kind regards...
