    this MB is a Maximus Formula and i have checked the cpu fan for noise by unpluging it also i had the 8 pin plug connected to the board not the 4 pin i have checked all the connections to the board they are all present also tried 2 different power supplies. sorry the "little LCD " is a small display that plugs into the MB and shows the posting routine .

  • xATOMx Mar 03, 2008

    yes i have tested the MB out of the case still the same result also tried 2 types of memory and 3 different video cards and as i said earlier i have tried 2 CPU's an e8400 and an e6700 still no luck :(
    i cannot check CPU and settings as it wont post .

    yes seems to me to be a hardware issue thanks for your help guys

    Please explain 'little lcd"

    Try these in the meantime:

    The buszzing sound near the CPU could be the cooling fan not anchored properly or worn out.

    Video cards make sounds when not properly connected.

    Check everything twice with the MoBo manual as you install.

    Take your time and be patient as you work.

    Let us know what you have checked, okay.

Hey Xatomx,

1. Let's check for shorting contact on that BoBo. By that I mean, make sure your MoBo soldering circuitry isn't touching casing metal in the back. The MoBo needs to sit 'insitu' on it's screws. Sometimes if it touches the case there is a short and warning sounds.
2. Are you using the same CPU on either MoBo? Try a different processor also.

3. Go over your Processor voltage and clocking settings.
4. Use different RAM and Viseo to see the difference.
5. Check your HDD, Power SW, Processor Fan, RESET carefully with the MoBo manual..
6. Try removing the MoBo from the case and keep it connected to the P/supply and Leds. Fire it outside the case and see what happens.

Sorry, but these are practical things any engineer would check for in troubleshooting: isolate the problem systematically.

Let us know what you find, ok.

    Hey, did you try a different power supply?

    I am beginning to feel your MoBo or processor either have a problem. I would start thinking warranty exchange route. No reason it shouldn't post after all these options. I hope you got it from good guys down the road from you. It would be best.

    Sometimes if you buy from a local shop, it's good to ask them to test those beats at the counter till BIOS posts and the babay cries, then you can take it home ready to grow.

    Good luck

Don't mean to butt in here but I'll bet the 4 pin_ATX 12v connector is not connected to the board. That 4 pin_ATX 12v connector give's the CPU it's power. Without is the system will not boot. Some boards will give off that weird sound you are hearing.

HI, i have the gigabyte MB GA-945P-S3- and i saw in GIGABYTE web site that i can go with C2D E8400 but with overclocking and saw awhile ago that there are another problem with the CPU MP in the bios of it...

Only the Gigabyte GA-945P-S3 revision 3.3 does allow C2D E8400 or C2D E7500.
However the C2D E8400 only by overclocking, which certainly is not recommended.

So the Gigabyte GA-945P-S3 mainboard revision 3.3, should work with the C2D E7500
with BIOS version FFd and FSB setting at 1066 MHz.

the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

E8400 or Q6600

personally i have the q6600 which is a quad core processor, all the others you listed were dual core, personally i use alot of programs all at once which is good if you have a quad core, but just for general music, data, and streaming, the e8400 is probably better for you, its a 3ghz processor.

ASUS P5VD2-VM SE support for intel core 2 Duo E8400

Doesn't boot correctly?

If the CPU isn't supported, in my experience, the pc doesn't boot at all. If this is the case, you will have to buy a new MB to support your CPU. Sorry.
