hello, I have a motherboard intel "S5000XVN and 2 processors (xeon).
After a year of good work, at the starting of the mobo LEDs are on but the video card does not work.
I changed the position of the processor, I tried the first processor and then the other, I changed my power, but no good result.
3 of 10 times without reason the mobo is working properly.
you have suggestions?
Do a CPU retest in BIOS (Advanced => Processor Configuration), and then update BIOS/firmware.
