Monitor will now display anything on power up for this motherboard

[chrisbek]

Hi Tom's Hardware members,

I recently got a computer from a buddy of mine. The system was just needed a stick of ram and a new power supply as he took both to use on another system.

The board I have is a GF-7050V-M7 made by biostar:

Full specs of the board are here:

I went out and bought the correct ram that would work for the board:

http://www.canadacomputers.com/product_info.php?cPath=24_311_313_621&item_id=013635

I have placed a Antec Earthwatts 380 Watt 80+ certified power performance efficiency supply into the case.

Final step was to clean the heatsink and reapply the thermal compound and insert the ram in slot 1.

Once everything was done I read the manual:

The manual says before powering on the system to make sure:

Before power on the system, please make sure that both JATXPWR1 and JATXPWR2
connectors have been plugged-in.

JATXPWR1: ATX Power Source Connector This connector allows user to connect 24-pin power connector on the ATX power supply

JATXPWR2: ATX Power Source Connector By connecting this connector, it will provide +12V to CPU power circuit.


I then made sure all the connections were made and then I turned on the system. The system immediatley makes a long winded beeeeeeeeeeep squeeling noise that never stops and the monitor never turns on. I power off the system immediately.

I then disconnected the JATXPWR2: ATX Power Source Connector and powered on the system thinking this is the problem. The computer turns on fine and the beeping has stopped but the monitor never turns on. I hear no beep codes or error codes. I hear the harddrive spin up and everything else appears to be working just fine. I turn off the system and I try another monitor I know that works. I turn on the system. Nothing displays.

Not sure what the problem is at this point.

Now my friend did say he had a graphics card in the system so I'm not sure if this is the problem
as he has the exact same board at home without a graphics card in it and it is just running just fine. I read through the manual maybe thinking the onboard video is disabled but I'm sure if this is the problem or how to fix it.

I have tried to reset the bios as outlined in the mobo manual through the jumpers but still no go.

Hoping for some help on this situation in determining what the problem could be.

Try just one stick of ram; remove the board battery with the power supply unplugged for one minute and reinstall. IF you get the system going with just one stick, go ahead and install windows. Then when you're done, download memtest and check both sticks one at a time. The onboard video setting is enabled by default, so no need to worry about it. Also have you checked "cpu support" section for your board? Be sure your cpu is listed on biostar's website and check the bios program required.

Long beep, repeating may be cpu overheating.

You need the 4/8 Pin ATX connector plugged in as it provides power to the CPU - No CPU and I don't think you get any beeps and nothing else will work.

The PSU is right on the edge of minimum sized, and you MUST connect both the 24-pin and 4-pin for the MOBO & CPU to operate.

Reading the Manual Beeps -> "1 Memory ref resh timer error" Therefore, try to re-seating the RAM ; try the slot closet to the CPU and failure try the other DIMM slot.

Turns out the problem the problem was the ram.

I had a stick of the old ram that my friend had originally. I knew the ram was bad as it had issues when memtest was ran but still worked.

I decided I have tried everything else.

After sticking the old ram in no beeping system display turns on and boots into the OS.

Thanks everyone all for the help. Tomarrow I'm off to the computer store to talk with the sales man who sold me the new kingston ram as he assured me it would work in the system I have.

Have fun with that - once in a while I go to Best Buy to amuse myself to hear the 'stuff' they say. :lol:
