I’m having an issue, I hope someone can point me in the direction of what needs replacing.
I have an Asus P8V77-V LX Mobo with an I-3570k CPU that as the header states, is giving a no input detected on video. I’ve tested both on board VGA and HDMI as well as HDMI on a GTX770. No input on anything. Verified two monitors functionality with a separate pc. I have a 500W cooler master power supply, and also a 600w Rosewill, both power the other PC no issues, but have the same problem here. There is also a 1TB Samsung SSD and a 500GB WD HDD. I have reset the CMOS. Both pulling the battery and flipping the jumper to pins 2 and 3. I’ve taken apart and reseated every component and plug in the tower. Including two 8GB HyperX ddr3 ram sticks. I do have a constant Mobo power light. My ram light blinks once when booted and stays off. All fans and case lights function. If a keyboard is plugged in it will dimly flash the backlight at powering up, then goes dark. I have swapped the CPU for a compatible 2nd gen i3.
The only semi-success I’ve achieved is if a do a minimal boot with nothing but the CPU, PSU, Mobo, HDMI via onboard, Corsair CC-9011050-WW case controls and fans. When I initially power it up, I have nothing, if I hit the case reset button, about 70% percent of the time, it will load to bios. At this point I can plug in the keyboard via USB 3.0, it will stay lit and functional. Once the keyboard is plugged in, if I reset, it will not load bios. It is not specific to resetting to get to bios, it has loaded on initial boot a few times with far less frequency. But as soon as I plug in any SATA, USB, or add a GPU. I get nothing on reset or boot. I have successfully had it boot to bios about ten times. When I get to bios and do not add any peripheral and hit the reset, it will load to bios every time, as long as I don’t kill power. As soon as anything is attached and reset, no signal detected.
I’m thinking it’s the motherboard, even though it’s kind of acting like a PSU issue. But both PSU’s function perfect in the other machine. Can anyone verify this, point me in the right direction if it’s potentially not a Mobo issue, and perhaps explain what might be happening?
If you need anymore information please let me know. First time poster but longtime lurker. I can usually find and fix a problem using these forums. But I’m gonna need some help on this one.
Thanks!
