I recently built my first computer. Here are the specs

AMD FX-8350
Nvidia GTX-760
8GB of Corsair Vengence ram @1600Mhz (1 stick)
Gigabyte GA-990FXA-UD3
Sharkoon WPM 600W power supply
128gb Kingston Hyper X SSD
Seagate Barracuda 2TB HDD

For the first 2 months it was working perfectly, I had even managed to overclock it up to 4.67 ghz and was able to play most games decently.

Seeing as i am not a frequent gamer, i did not keep these overclocked setting, but reset the bios settings to their "Optimized Deafults".

One day, I decided to overclock the pc again. I raised the fsb from 200 to 235, but stupidly enough did not change anything else (I forgot). Everything else was left on auto.

From the moment i pressed "save and exit" the system has never worked properly again.

now, when i go to turn it on, it take 10-15 seconds for the screen to power on (normallly it took no more than 5). After that, i briefly see the bios screen. Althought the keyboard and mouse are both active, if i press the keys to enter the setup, nothing happens.

After the bios screen, for a moment i get a black screen with a flashing underscore. Then i get a blue screen with the gigabyte logo on the top, which is there for about 10 seconds. Then the computer restarts and the whole thing happens again and again.

What should i do???
Is the CPU broken??
Is the MOBO broken??
Can I fix this???

Any help would be highly appreciated.

Do what Axlfone said and see if it posts with bare minimal, cpu, gpu, one stick of ram, no hdd, nothing else but what is needed to get post and video. Could be bad ram or a bad psu, i never heard of the psu u listed. Doubt the board or cpu fried as u said uve done it before other than not touching auto settings when moving the fsb, which is not the best way to OC a black edition cpu lol.

Being a 990fxa board and newer, it has failsafes for overlocking that will shutdown before anything can be damaged usually. so the bios reset should help.

If u can get bios reset tp default or optimized or failsafe settings, or remove cmos battery or hit the bios/cmos reset button if u have one.
