Mobo: ASUS M5A97 R2.0 Bios rev: 1503 CPU: AMD FX 8320 RAM: Patriot 4GB PC3-10600 PSU: Thermaltake 500W TT-500NL1NH-1 Graphics: GV-R645-1GI Rev: 1.0 HDD: WD Blue 500GB. The PC runs POST. However the last test, the LED stays on and that is the BOOT_DEVICE_LED. After that nothing on the monitor. It's getting a signal, it's just.. blank. I've tried: Updating BIOS via Flashback. (Just shows me a solid light like it hates me) Swapping out Hard drives Swapping out SATA cables No Hard drive USB drive Swapping RAM Swapping PSU Re-seating CPU Tried a new CPU cooler Shorting CMOS pins Removing CMOS battery for half an hour. Swapped out graphics card Changing GPU to second PCI-E slot Re-seating everything including CPU (again) Running out of ideas really. What have I missed.
