Specs: Q6600 Crucial Ballistix Tracer - 2GB Abit IX38 Quad GT MoBo CoolerMaster 750W PSU 80GB WD HDD 500GB WD HDD XFX 8600GT Plugged a buddy's SATA drive in to test some things. Shut the system down and unplugged it, put my side panel back on (plugging in my side fan), and tried to re-boot and nothing. I'm getting post codes: 8.2. - Enable ATX power supply 8.3. - ATX Power supply ready 9.9. - Complete power off sequence That'll run in constant rotation until I pull power from it. If I unplug the HDD and DVD-RW it'll hold at 8.2. It did cycle through once but that's it.
