I just finished putting together a custom built computer. I've double checked all connections, reset the CMOS and CMOS battery. It powers on, fans power, CD drive spins up, but absolutely nothing else happens. No CMOS boot screen, nothing. Monitor acts as if it's not even connected to anything. I have tried 2 different monitors and even grabbed a VGA-DVI adapter to see if the VGA connector on the mobo was bad. I have also swapped out the RAM to no avail. Here's the setup:

BIOSTAR A880G+ AM3 AMD 880G HDMI Micro ATX AMD Motherboard

HITACHI Deskstar 7K1000.D HDS721050DLE630 (0F13178) 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive

Rosewill RD400-2-DB 400W ATX V2.2 Power Supply

AMD Athlon II X3 455 Rana 3.3GHz Socket AM3 95W Triple-Core Desktop Processor ADX455WFGMBOX

LITE-ON DVD Burner - Bulk Black SATA Model iHAS124-04 - OEM

Crucial 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model CT2KIT51264BD1339

Any BEEP / ERROR codes?

No beeps. No error code. Monitor doesn't even come on. I did the bench test. Stripped it down to the basics: CPU, CPU fan, 4-pin CPU connector, 24-pin mobo connector, and 1 stick of RAM. Same problem. Possible bad chipset?

put a 80+ quality psu in it

Do you really think it's the PSU? I can test that, but it'd require taking the PSU out of my personal computer.

then check it

Same advice as above: http://www.techsupportforum.com/forums/f255/how-to-bench-test-troubleshoot-your-system-171424.html

Make sure the MOBO is not shorted...

Strip it down to minimum: Mobo,CPU,GPU(if not built in),RAM

Then start adding things in...

As I mentioned above, I have stripped it down. Still doesn't work. I am going to give dai's suggestion a go when I have time to shut down my computer.

 

[Laxer]

Sorry missed that...

Try booting without any RAM... do you get any feedback from the MOBO?

and yes I agree that the next step should be testing with an alternative PSU.

 

[ChadT]

Alright, swapped PSUs. No change. I'm starting to think it's a bad chipset on the mobo. Also, may I ask why this was moved to Power Supply and RAM Support?

 

[Laxer]

I don't know why it was moved. Whoever moved it must have thought this was a more appropriate section.

Were you able to get any beeps from your mobo starting it up without any RAM in?

 

[ChadT]

Yes. Continuous, non-stop beeping. Rather annoying, really. I put 1 stick of RAM back in and got 2 rapid beeps a few seconds after powering.

 

[dai]

what psu did you swap to

make
model
wattage

2 short bios beeps=

Memory parity error A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad

run memetest on the ram 1 stick at a time

Memtest86+ - Advanced Memory Diagnostic Tool

make sure you are seating it properly

the clips clicking over does not mean it is seated

 

[ChadT]

Corsair TX750 750W

I have triple checked the seating with both sticks and still get 2 short bios beeps. Is it possible I received 2 bad sticks? I can't use another machine to test as all the others ones I have take DDR and DDR2 only.

 

[Tyree]

Test the Mobo by removing all the RAM and booting. No RAM and no beeps indicate a Mobo problem.
It is possible to receive two bad RAM sticks but the only way to be certain is to try different RAM in your PC or try your RAM in another PC.
When doing a bench test precisely as instructed and there is no joy, follow the last paragraph.

If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.

 

[ChadT]

Removing the RAM causes a continuous, non-stop, annoying-as-hell beeping to occur. As for testing the RAM in another computer or other RAM in this computer, this is the first DDR3 mobo and RAM I've bought. I have nothing else to test. I have swapped out the PSU with no change. I know it's a mobo issue. What I don't know is if it's something I'm doing wrong or if the mobo itself is faulty.

 

[Laxer]

You are testing the mobo outside of the case correct? (on a box or something similar)

If not please try that.

That would indicate the Mobo is OK.

As I have said twice before, this is the only set of DDR3 RAM I own and this is the only DDR3 mobo I own.

A880G+ :: Motherboard :: BIOSTAR
--> CPU Support

If you plan to upgrade processor from your existing unit, please update bios first before changing or upgrading processors.

I had the same issue with a Gigabyte motherboard, it was an AM3+ CPU, so this MAY not be the same issue as you, but the symptoms sound much the same. To fix it, I needed to go out and buy a new CPU, a crappy one, didn't need to be fantastic, and update the BIOS.
