computer turns on, but wont display anything and the processor fan runs really hard. my keyboard and mouse wont light up either...

i have tried
-reseating the graphics card
-taking out the battery for a bit
-switching around ram
there's more i've tried, i just cant remember

it used to work fine, no problems but now it wont even boot.

earlier today i got it to boot but now its back to running hard and not turning on

(what i can remember of) the specs:
intel core duo
4x corsair 1gb ddr2 ram
geoforce gtx 750ti superclocked edition
430w evga power supply

idk how to see what your motherboard is

i have an i5 processor and arctic fan to go with but my motherboard cant use it (supposedly)
