I'm building a PC based around the DX58SO motherboard. The problem that I'm having is that there is no video (including the BIOS screens) nor are there any beep codes.
For diagnostic purposes, the PC was built outside of the case. I'm also building two of these PCs so I have two of everything.
The configuration I'm trying to get to is:
When I power up the system up, the fan whir and spin, but I never get to the point where I can see anything on the screen.
The two motherboards are slightly different. One is rev 501 which has a default BIOS of 2127. The other is rev 703 which has a default BIOS of 5200. The latest BIOS is 5600. The i7-965 requires a minimum BIOS of 2388 so I know I have a problem with the older of the boards.
The latest BIOS was downloaded (SO5600P.bio) and burnt to a CD. I remove the BIOS jumper, put the CD into the optical drive, boot the system, but the system never seems to boot from the CD. The light flashes on the optical drive for several seconds and then goes dark. Burnt another CD – same result. Swapped the drive for a DVD drive – same result. Try it on the other system – same result.
So on the rev 703 system
Swapped the memory for others - including DDR3-1333, other sizes and different slots - and the fan whir and spin, but I never get to the point where I can see anything on the screen. Remove memory and there are no beep codes.
Removed the battery for an hour to reset the BIOS – same result
Swapped power supplies for two others – same result.
Swapped the CPUs – same result.
Swapped the video card for four others (three PCIe-x16 and one PCI) – same result.
Search the web. It seems a number of people have this problem but there is little consensus on how to fix it.
Tried this multiple times with the same result
So any suggestions ?
May I know if you tested the motherboard without the video card? I recommend you updating the BIOS using the F7 method.
Here you can get the instructions:
Thanks for the suggestions.
I removed the video card and the fans whir and spin. No beeps.
I tried the F7 method with an unbootable USB but I never get to the BIOS screen. Nonetheless I booted up and repeatedly pressed F7, but this only got the usual behavior (the fan whir and spin, but I never get to the point where I can see anything on the screen).
I tried the F7 method with an bootable USB and got the same.
I tried F2 and got the same.
You have done many troubleshooting steps. I recommend you contacting our local support for further assistance.
Here you have the contact information:
I am sorry to hear you are still having problems. My recommendation is to stay with the Service ticket we have created for you and continue with the support through that line.
Yes, I too had the same problem, could not start even though the electrical flow was normal.
To achieve the restart I tried removing the memories and wiping contacts with isopropyl alcohol.
I got the normal power for a few months it worked perfect.
Mysteriously he stopped again. I changed the video, and I was able to boot again. The above video is useless.
A mystery, I am very sorry to acquire this mainboard ...
I managed to fix the problem. I replaced the Mainboard by an equal Amazon. I would have preferred an ASUS Rampage III but there was new. Increiblemnte everything works fine for now, doubts about which it is the component that failed in my front plate.
