Hello there, I'm currently having issues with my PC to even send video signal and for the motherboard to load bios.
These are the full specs:
-MSI Big Bang Xpower x58/ LGA1366
-i7 950 3.07 GHZ
-EVGA GTX1060 6GB SCC
-24 GB RAM Ripjaws 1600 MHZ (6X4GB STICKS)
-Corsair H45 CPU Liquid Cooler
-Thermaltake TR2 600W PSU
-Corsair Spec-03 Case
-150 GB internal hard drive (With windows inside)
-4 TB Seagate Barracuda internal hard drive (new).

Last year on november I posted my thread about "Super low FPS GTX1060", after finding that it was actually the CPU overheating to 100° celsius the main problem, I switched to the Corsair H45 cooler, everything good so far, then just today I bougth the 4TB seagate barracuda, installed it on the correct sata 6gbs slot, windows detected it as "unallocated" space, so I gave it a simple value, it was detected finally then, but then I noticed that only 16 GB of ram where being detected, so I got my hands on the pc, unscrewed the case and verify the ram sticks and slots (Nothing seems bad), so I reinstalled all the ram sticks once again and then the fate came, I plugged in the power cable and turned on the PC, all ligths turned on normally but no video signal, beep sound or HDD activity ligth on the frontal panel doing something (It was just turned on all the time) and also I noticed the 1060 spinning efortless one fan at the time after the another, then I tried only one stick of ram but yet again no clue of something.

Could it be a bad cable connection in the motherboard or the battery life already passed out? Could it be the sata cables that are damaged? Or what could be it?

I hope you help me to solve this issue, waiting for your response and as always thank you for your profesional and free aid.

Best regards, Bingo Perroso.

First check that all of the motherboard power cables are connected. In fact remove and reinstall the CPU power and 24- pin to assure that the connection is good (also check the other end as well if it is modular.

Then I would remove CPU. Examine it for any bent pins or thermal paste in the socket. Then reinstall the CPU and CPU cooler with fresh thermal paste.

Re-seat the graphics card and confirm that the PCIE power cable is connected.

Then try rebooting.

Edit: Clear the CMOS.

Can the problem from no HDD activity be that I changed the original positions of the SATA cables? Because I have tried everything else, CPU is new, I see no change with the CMOs battery and also tried with a GT210 but it stills does not send video.

The HDD activity LED is more than likely a cabling issue with the front panel connectors. You can change out the SATA cables.

Try the graphics card in different slots. Try different monitor and PCIE cables.
Check the motherboard video outs without the graphics card.
Try switching out the PSU.

Even though there isn't a new BIOS version, update it anyway to exclude corrupted files.
