Not sure what the problem is, I have not reset the CMOS or taken the CPU out yet, but I have taken out the graphics card and the ram to no avail. What happened was i could smell a plastic burning kinda smell coming from my computer and 10 minutes later my computer shut off. When i try to turn it back on three red lights show up on the CPU/GPU/RAM. Which obviously means something is wrong, i took out the GPU and put it back in and the red light has gone from the GPU indicator on the motherboard. Which i am assuming must be good, but the ram and CPU lights remain, i took out the ram and put it back in and the light remains. Something must have burnt out I take it, maybe the power supply im not sure, the temp on all th components were always good, so i have no clue what went wrong or how to fix it 
Not sure if this is the right thread so i apologise in advanced, any help would be very welcomed.
