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.
