Hello everyone, this is my first post.
I'm building a computer and I can't make it boot, not even the BIOS.
Components:
- AMD Phenom II 1090T X6 3.2Ghz
- GA-890GPA-UD3H
- Corsair Value Select DDR3 1333 4GB 2x2GB CL9 (CMV4GX3M2S1333C9)
- NOX Apex 700W Modular
The problem:
1- The CPU 1090T, that I think is supported, is connected.
2- One RAM module is connected to the first memory bank.
3- Box power button switch and speaker is connected to the MB.
4- The PSU is connected to the MB, the 24 pin ATX connector and the 8 pin 12V connector.
5- The screen is connected to the D-Sub integrated graphics card.
6- I connect the power cable, switch on the PSU and press the box power button.
7- The CPU fan and the PSU fan start and work for 2 seconds.
8- The fans make a noise like "prf prf prf" and they stop, the system powers down.
9- The screen has no signal.
Modification 1:
Same configuration but no memory installed.
1- The CPU 1090T, that I think is supported, is connected.
2- Box power button switch and speaker is connected to the MB.
3- The PSU is connected to the MB, the 24 pin ATX connector and the 8 pin 12V connector.
4- The screen is connected to the D-Sub integrated graphics card.
5- I connect the power cable, switch on the PSU and press the box power button.
6- The CPU fan and the PSU fan start and work for ~5 seconds.
7- The MB makes one long beep (just one) and the system powers down.
8- The screen has no signal.
Modification 2:
Initial configuration but no 8 pin 12V power cable is connected.
1- The CPU 1090T, that I think is supported, is connected.
2- One (or two) RAM module(s) is(are) connected to the first (and third) memory bank(s).
3- Box power button switch and speaker is connected to the MB.
4- The PSU is connected to the MB, the 24 pin ATX connector.
5- The screen is connected to the D-Sub integrated graphics card.
6- I connect the power cable, switch on the PSU and press the box power button.
7- The CPU fan and the PSU fan start.
8- The screen has no signal, nothing more happends, the fans just work, no beep, no screen signal.
Can anyone help me with some tip, or does anyone know what could I do?
Thank you very much for your help

Hi there and welcome to the forum,
before we get started could you post back with the revision number of your motherboard as there are 3 versions and it will be easier if we know which board we are talking about?
If it is revision 1.0 there could be a problem with the CPU not being properly recognised as you would need the board to have BIOS version F7.
-
Thanks for the answer.
I'm at work right now and I forgot to read the revision, I'll post it later when I get home.
It's very probable the MB is rev1.0, if it is, is this the behaviour it would has if the CPU is not supported? Not even a beep?
-
It could do this. I have had many different things happen if the CPU is not recognised such as no POST, POST but Unsupported CPU message on screen, Shutdown. The first thing we need to do is make sure that it isn't just an incompatible CPU causing the problem.
The steps that you have taken so far are precise and the only thing I would do differently is try building the PC outside of the PC case (you can place the Motherboard on the box it came in to do this) as there could be a problem with the motherboard shorting on the chassis. This would also cause the symptoms that you have.
As with all things, it comes down to a process of elimination until we can find the problem and there are no easy answers, sorry.
-
Thanks again :)
Tonight I'm going to try what you said, booting with the MB out of the box. I have a friend who is going to give me his Athlon II X4 CPU to try in my MB to know if something is wrong with CPU/MB.
Also, I don't know if you may have some experience with this, do you think it might be a problem with the memory not being compatible with the MB?
-
To be honest, even if the RAM is faulty you should still get something from the motherboard, even if it is only a series of beeps from the speaker.
I think the probable cause is the motherboard shorting somewhere, this can be from a standoff in the wrong position, a screw or some other metal object being left under the Mobo or the motherboard not sitting properly in the chassis, rather than anything major. That's why I suggested building the PC outside of the case as it will eliminate this as a cause.
The possibility of the CPU not being recognised is also an option and as I stated before, at this stage it is really just a case of finding out why you can't BOOT.
-
I'm trying it this night, I'll post the result, thank you very much for your help.
-
absic, thank you very much, I've boot the MB outside the case and it works, I have changed a metal plate from the box that may be shorting the MB, I'm not sure how to explain it even in my language, it's the metal that covers the MBs external connectors (USB, DVI...), it has some pins that press the connectors, I've bended them to avoid any contact with the MB.
Now it's working, I think fine, I'm installing some OSes and I'll see if it's working fast,the MB is supposed to support the X6, it's rev2.1.
-
Hi,
pleased you are getting it sorted out and also that it was something simple. Yes, the backplate can cause the Mobo to short out if not fitted properly and is something I have come across many times.
Your CPU is supported out of the box on the Rev 2.1 so no problems there.
-
Well, the computer is working really great, fast and stable. I would like to thank you again and ask to a mod if he/she could change the topic to show the issue is [SOLVED], it may help someone.
-
Don't look now but Absic is the MODERATOR ;)
-
And I've given it a Thumbs Up as it is the only thing I can do to show it is resolved.
