No Video output or dvd response

Sounds like either a faulty graphics card or motherboard then...

 

the card can be replaced, what can i do about my cpu temp it reads 103 F roght now and my heatsink fan is running at 1200 rpms

 

103F is 39C, while that's not as low as a lot of systems, it's perfectly within acceptable limits. The temperature that matters is when it's running full load, so reserve judgement on that until then.

 

i have the ultra md3 media dashboard installed and when the temp spikes to 124 f (when playing spore) i get a warning beep from it. is the beep anything to worry about?

 

i just installed a program called "speedfan" and it says that the only thing that is above the temperature that it should be is the core (which is listed twice) one is a 54 c and the other at 46 c the 54 has a critical heat rating and the 46 just a warned rating. what does it mean by core and how do i cool it.

 

Speedfan just puts the flame symbol beside anything that's above 50C, it's fine for cores to get well in excess of 50C, so don't worry about it.

 

thats good news... any recommendations on a video card?

 

Depends on your budget really, I typically recommend the Radeon HD4850 for $160 or so (after rebates) or £110 in the UK.
