Could it be related to a case open detection? What are the specs / model of your PC?

Some prebuilts have a switch that detects when the case is open, and may warn in the BIOS. Since you have a custom rig, I doubt that is it though. My guess then is that something is shorting on the case or blocking a fan or something when the case is closed. Check your wire management and possibly re-seat the motherboard in the case. What motherboard do you have?

Could this be P67 SATA degradation? Did you have an early-batch P67 mobo? Did you ever get it exchanged for a bug-fixed B1 revision chipset board?

Just throwing out some ideas here.

The bug was that the SATA port driving transistors had a weak one, and SATA could fail/degrade on some of the ports.

Could always try throwing in an ASMedia AHCI SATA PCI-E x1 dual-port card, just for the SATA SSD, to bypass that issue if it's that.

i have no knowledge regarding what you said i bought this motherboard in 2012 and there is no change since then looks like ssd is culprit here without ssd installed pc has never hanged at post screen what should i do if i go to rma it how will they check it ?
