ASUS Crosshair V Formula Z motherboard
AMD FX 8350 4.0 G Processor
4x 8Gig G-Skill Ripjaw 2133 RAM (32G total)
XFX AMD R9 390 8gig GPU (replaced AMD 7950 3gig)
Seagate SATA 2tb HDD
750 W PSU
I woke up one morning to no display when booting PC. I initially thought it might be the graphics card. I wanted to upgrade anyway, so I jumped the gun and purchased a new one. Same problem. There is no display.
Here is what troubleshooting I have done:
Tried 3 different monitors
Tried all other PCI-E slots
Tested all voltage on PSU using a multimeter (exactly where it should be)
Removed all RAM and GPU.... I get a long beep followed by 2 short (indicating RAM is missing).
I insert one RAM stick (tried all sticks separately in different slots), and I then get one long beep followed by 3 short beeps (missing GPU)
Insert graphics card and then I get a successful POST beep, and still no display.....
I downloaded the latest BIOS from ASUS and flashed/updated using the designated USB/ ROG connect button on back of board
Also disconnected/reconnected HDD
The Crosshair V Formula Z also has a Q-Code display during boot which shows no errors.
There are also 4 led lights for CPU, GPU, Boot Device and DRAM. Manual states if there is an issue detected, the light will stay on.
They are all off...
I feel like I have narrowed it down to possibly motherboard issue or CPU, but would I get a successful post beep with a malfunctioning CPU? Sadly I do not have a spare CPU or Motherboard kicking around for testing.
Another thing of note: over the past couple months, my pc would randomly run slow, take forever to load program, and games ran a bit choppy. I would reboot, and everything would be fine again....So this makes me thing maybe CPU? Sigh....
