Hello, here what I have done so far:
Tried to Upgrade the BIOS to solve some ram problems, the board would not allow me to run the memory at 1333, so that I needed to update it.
Update method: Within Windows (claimed as "THE MOST POPULAR")
Results: Everything was OK. (UPGRADED TO 5020), after the flash finished, I did some stuff on windows and turned the system off, later on when I wanted to do some more work the board does not POST, No beeps, No erros, leds are on, fans are spinning (AT TOP SPEED), and next what test I have done:
Now try to boot the system only with power supply, motherboard, GFX card and cpu connected (no memory)
Does the board issue any beeps? yes 3 beeps, then pause, then 3 beeps again and go on... non stop.
Put one memory module on the board on the slot dimm 0
Result: still black screen, also did in channel A(0,1), B and C with 1, 2 and 3 sticks and tried all the sticks 1 by 1, also tested the sticks 6 of them in another dx58so and they are OK.
Switch the bios jumper configuration of the board to the configuration mode
Switch on the system
Result: Black screen as well
Last Step D: Note Update the bios using the recovery mode only
CMOS Clear again
Download the latest bios file from the download page website
Copy the bio file to a fat-formatted usb memory stick
Remove the bios jumper from the board.
Connect the usb stick on the target machine.
Make sure there is no other usb devices connected on the system
Switch on the system
Wait for the bios update to complete.
Put back the bios jumper to its normal position
Try to boot the machine.
If it does not work, try another graphics card.
Tried ALL flashing methods (iFlash, usb stick, and cdrom), the usb ports have power cause the usb stick led turns on, but the board is not reading the data from the stick, tried with the jumper in the 3 possitions, pins(1,2), (2,3) and without jumpers (same result all cases), same with the cdrom, it does turns on, read the cd/dvd then the light turns off and nothing happens, tried 3 graphic cards, 1 nvidia 9800gt 1gb, 1 nvidia 8800 gtx 512mb and also bought(e-bay for 3$ usd) a regular PCI trident 1mb (non pci express) and tried with 3 different monitors and still nothing (all 3 cards are working fine with all 3 monitors tested on another dx58so.
Also the cpu is a D0 step core I7 920 and I switched it with the other dx50so board i have and the cpu its OK, al tested the other cpu on the "DEAD BOARD", still nothing, changed the PSU 3 brands going from 550W to 1000W, and nothing, all the PSU tested with ALL THE DDR 3 STICKS(CORSAIR XMS3) 6 in total, and all this tested also with both CPUs and both board, the non dead board works good with all the cpus and all the PSUs and all the memory, also is running the 5020 bios version.
Also checked with a magnifier glass the socket pins and are OK, same as the working board.., cannot rma it cause im from Venezuela and intel does not offer that kind of service for latin america, can not go to the store where i bought it cause they got broken and there is no store anymore... is there a way to force the bios to post? or force to read the usb?. I have an acer aspire one and whenever the bios fails, i just put a usb stick on the port, press fn+esc keys then press the power and thats it, it will flash the bios no matter what..
Removed the battery for 5 or more hours, replaced the battery with the Good board battery, and I ve done the WHOLE process with all the variants inclued, created a test sheet on excel and everything.
Thanks in advance..
