Video problem or Mobo problem?

By j_steib ·
I have just bought several new items to greatly improve my PC gaming, but having put them all in, my computer will bnot start up.

All the LEDs light up, all the fans start up and the CD drives both appear to be working fine, but thats it. If I could get the BIOS to load up but then I would have somewhere to start but the monitor stays on standby.

The new components are all compatible - i will list them here

*ASUS M3A AMD 770 Socket AM2+ 8 channel audio ATX Motherboard
*Kingston 2GB (2x1GB Kit) DDR2 533MHz/PC2-4200 Non-ECC CL4
*Gecube HD 3850 Pro 512MB GDDR3 Overclocked Edition Dual DVI PCI-E Graphics Card
*AMD Phenom 9500 Quad Core 95watts AM2+ 4MB Cache 2200MHz Processor
*Arctic Power 700W PSU - With PCI-E, SATA, 20+4, ATX12V, 8pin +12V Connectors
*350GB Sata Harddrive (cant remember make)

Any ideas on what the issue could be or how I can fix it??

Well first things first

by OH Smeg In reply to Video problem or Mobo pro ...

Look here at ASUS's Web Site and Identify your M'Board as the M3A isn't listed by ASUS.

The other thing that you need to look out for is Chip Set Incompatibilities where a Video Card is Incompatible with a M'Board Chip Set. When this happens the Computer Will Not Boot or Do anything as there is a Incompatibility between the Different Chip Sets which prevent the computer starting up. If you are not hearing any Beeps from the M'Board this is a possibility.

You also need to check the assembly to make sure that there is nothing wrong there so pull the CPU's Heat Sink/Fan Combination and check the the CPU is correctly inserted in the Zero Insertion Force Socket and that it is correctly Locked.

Also check the RAM and Video Card for correct fitting and all the Power Supply wires. Pay particular attention to the Second Power Socket on the M'Board make sure that it's actually plugged in and also make sure that the Video Card is connected to the Power Supply if that option is supported. With most modern Video Cards they require their own Power Supply connection because the M'Board is not capable of delivering enough power to run them.

BIOS? Can this be the problem?

by ThumbsUp2 In reply to Video problem or Mobo pro ...

I'm not sure I'm reading them right, but according to the specs page on the M3A motherboard that you listed, the BIOS are version 2.3? It says: 8 Mb Flash ROM, AMI BIOS, PnP, DMI2.0, WfM2.0, SM BIOS 2.3, ACPI 2.0a, ASUS EZ Flash 2, ASUS CrashFree BIOS 3.

According to a FAQ found at ASUS, support for the AMD Phenom 9500 requires BIOS version 0301 (3.1?) with a flash offered for download. Could this be the problem?

Also, checking the ASUS forums, there seems to be limited support for the Phenom. You might want to read this forum post at ASUS:

2 things spring to mind

by tintoman In reply to Video problem or Mobo pro ...

If I may add my little ol opinion.
I have seen this a couple of times when I have built new or repaired systems.
It seems to invariably be incorrect or malfunctioning RAM, or morelikely that your video card requires more power than than the PSU has to offer, I don't know what the requirement is for your card in particular but if for example it needs up 400Watts and your PSU is rated maximum 350 you wont get any video.
It might be worth just checking the CMOS settings to see if the PCIe slot needs to be enabled as well
