I've been happily using a 3770 on a very nice Z77-DS3H for three years. Bought it circa 2003 and the machine was amazing.
Decided to upgrade and gave this setup to my kid. Started to mount it on Corsair Spec Alpha + Corsair SSD + 16gb Corsair DDR3 (2x8gb).
Machine was working fine, but then, all of a sudden, the -already described here- symptom of constant reboot (2 quick restarts: fan on, psu spins, fan off + one boot with Gigabyte SPLASH screen + a blank screen with "Gigabyte DUAL UEFI Bios" header shows up, 5 seconds and the whole loop restarts).
Already unplugged everything, leaving just the Motherboard, single DDR chip + just the heatsink! (yes, it's a thermaltake FRIO OCK, can handle fine for quick testing).
The only way to remove it from the loop, is to start trying to press several keys (DEL + ALT + F10 + F11 + F12) randomly just before the 5 second splash screen. When I get to that point, it says: BIOS Corrupted! Restoring previous one...
Well, the point is: What might be causing the BIOS corruption? When I changed the MOBO from cases, I used Coollaboratory Liquid. I'm very careful, but, maybe I dropped some around the processor area? I ended up disassembling everything, cleaned with Isopropilic Alcohol and replaced with Gelid Extreme (non conductive).
Another "issue" I had when assembling was that, Thermaltake FRIO fans were acting weird. I touched the CASE's FAN controller and the voltage chip was burning like hell. In the end one of the fans stopped working and I decided again to triple check all FAN connections: nothing. Decided to throw away the original FANs and adapted a Corsair SP120L PWM to the heatsink: perfect, no heat on the fan controller and so on...
So, any ideas? I'm able to basically use a multimeter. Maybe I can check some of the MB components for some failure? Maybe there's still a short somewhere between the case and the MOBO (im using the screws on the case just like I always do, but, who knows)?
All the best,
