Case - see below (swapped from NZXT Phantom 630 to Fractal Design Meshify C)
Scenario:
I helped my husband swap out the case for the above system from an NZXT Phantom 630 to a Fractal Design Meshify C to save some room on his desk (the NZXT was unnecessarily big). During the move we know I very slightly bent two pins on the mobo. My husband used Linus' video and a clean safety pin to repair the pins and they seem to be in perfect alignment as far as we can tell. Before the re-case the computer had been working very well with no issues for about the last four years. This system has never been overclocked or even pushed very hard and it has received all driver updates, windows updates, and BIOS updates.
The problem:
After completing the re-case we attempted to boot the PC. The computer would power on for about 2 seconds then power off and cycle like this in a loop. During this time both the main and backup bios lights on the mobo would flash red alternately. This board has Debug LEDs, but there were no codes showing. After some research we performed the following steps:
- Reduced the system down to one stick of RAM (tested the 4 individual slots to make certain it wasn't a bad RAM slot), CPU, and Mobo to make certain it wasn't a peripheral issue.
- Used the CMOS_SW button as described in the manual.
- Tested the system with another known working PSU (Raidmax 850watt Gold).
- Removed the CMOS battery overnight (about 10 hours) and reinstalled.
- Bridged the CLR_CMOS for thirty seconds as described in the manual.
We switched the system from the main BIOS to the backup BIOS and swapped from dual BIOS to single BIOS using the switches on the mobo. The system's behavior changed - it now turns on (again no codes on the LED Debug), but there is no signal to the monitor. The light next the the main BIOS is still red, but there is no red light next to the backup BIOS. At this point we tried these additional steps:
- Tried both the Displayport and the HDMI from the mobo with two different known working monitors (no GPU installed still).
- We reinstalled the GPU and tried the same ports plus VGA from a third monitor from the ports on the GPU.
- We rechecked the power supply with the same known working PSU from above.
- Tried reinstalling everything as it was before we re-cased. Just for giggles at this point and because we're tired.
The monitor issue persisted through all of this. The system turns on, all of the fans spin up, there are no codes on the LED debug, but the light next to the Main BIOS is still red. We had just one stick of RAM installed in slot 1 and no peripherals plugged in until we were testing the GPU's ports.
Have we missed anything? Did I kill my husband's Mobo? We've rechecked the pins and cooler and 100 other little things along the way that I'm sure I'm forgetting to describe. We've cleaned off and re-applied thermal paste and the stock cooler each time.To be fully transparent, BIOS issues, if that's what this is, are a little over my head. I'll provide any further information that is needed. Help?
