    With the Mainboard TA785G3 HD I have the following problem:

    - At startup it hangs at “Checking NVRAM..” or “Hardware Monitor”-Screen with a continuous system beep.
    - Keyboard Input is mostly not accepted. This occurs especially entering BIOS (which to enter mostly works), At BIOS-setting ‘Enter’ and ‘+’ / ‘-‘ – keys are mostly not accepted and other keys (moving through the menu) do not react or react extremely slow (+10 seconds).
    - I wasn’t able to install a system.
    - Every 25th try or so configuring BIOS-settings works, but at restart it hangs again.

    I did reset CMOS already – does not help.

    Systems components:

    - AMD Athlon II X2 220 AM3 2x2,8GHz Tray 65Watt
    - Coolermaster Cooler 939/AM2/AM3 PWM retail
    - DDR3 PC1333 VMAX 2048MB PC-10600 1333MHz CL9
    - 400W OEM Retail 24pin 80x80mm retail – power supply
    - PS2-keyboard - double checked, ok
    - PS2-mouse – double checked, ok
    - CRT-display, connected via VGA – double checked, ok

    The vendor already changed the MB once, therefore I am confused if it's the MB itself in general or within this configuration.

    It might be the RAM or the CPU or the power supply?
    On the other hand Memtest did run 90 minutes and showed RAM ok.

    I appreciate any suggestions, help, hint...

    Why was the MB replaced? Was it for this problem?
    How many sticks of RAM do you have?
    I'm guessing the MB has onboard video?

    Yes, the MB was replaced for the same problem.
    I have one stick of RAM.
    Yes, the MB does have onboard video; it is sharing 256 MB (? - think, I'm right!) of RAM for onboard video by default.

    Meaning of continous beep depends but despite memory testing could still be RAM. Other possibilies include video or PS. Believe you can add video card to MB. Always a matter of troubleshooting by replacing parts which isn't always easy or economical. Might try starting up system with everything detached. Like drives, keyboard, mouse, etc. At least that doesn't cost anything.

    I had to change the ram to another (similarly priced, same specs, but _other Brand_!) and it works just fine. Taking in account what is said on other boards as well, there seem to me some odd incompatibility issues of some Biostar-MBs with some brands of RAM.

    Thanks for your advice.
