Yesterday i took my pc apart cleaned the dust reapplied thermal paste to both the cpu and gpu,(GTX 750 1gb ASUS) put everything back togheter and my pc would not signal beep codes and monitor shows no signal. I tried a old 9800GT and the pc booted normally i tried the 750 on another computer and it does the same what could be the problem i took pics of the 750 where i spotted something burned, any opinion will be in Help

You probably nicked the main chip, it is very delicate and unprotected. Even a small scratch will put an end to it. Take a high-res shot of the die and I will be able to tell.
The bad component you spotted is likely a shot capacitor for the memory power phase... but if it worked before you took it apart, it should not be the issue.
