I hope some of you can assist with this in-depth analysis!
Trusty 2500K rig, which had worked wonderfully for many years seems to have had it.
Spec:
P67A-UD3
2500K at Stock
Water Cooled
2x 2Gb Rip Jaws 2133Mhz
1x Crucial SSD
1x 500Gb HDD
Sapphire HD5670 Autotuned OC
Symptom: Will not Power Up
Pressing Power On causes a very brief flash of the blue fan lights then nothing. No beeps, no fan starts, no green light on mobo.
What Happened Prior: Just before the problem happened a game patch applied which caused a BSOD. Since then will not power on.
Anything else to note? The GFX has been running for a month on Autotuned OC. Temps fine.
What Tests Have Been Performed:
The PSU was swapped.
The GFX was swapped.
No joy.
What about the BIOS:
This is interesting. I cleared the CMOS but still no good. Then on the off chance I cleared the CMOS whilst the PSU was active. This brought the mobo to life. Fans spun, green light on MOBO, disks spun up. But still no Display.
Unable to power down cleanly. Pressing power button instantly shuts off (which is unusual, as it is different to a graceful powerdown)
Anything else to note? The BIOS has always been a bit of an issue with this rig. It didn't like shutting down without a full turn off at the wall. If you shutdown it would then fail to boot and run in an endless cycle of restarting. This could be totally different to the duff problem experienced now.
What Else Have You Tested?
I have proved the GFX and the PSU work because they were tested in a 4770K rig. I have also tested the GFX in a different slot. Run the Mobo without anything connected to it.
What Could Be The Problem
I think the Mobo is flaky. Maybe the GFX OC just tipped it over the edge, damaged something?
Options
This was going to be replaced next year so I don't want a complete rig right now. I guess I could purchase a second hand 1155? But I also don't want the hassle of finding out it's not the Mobo but something else!
Any suggestions?
