I build a 80% new pc on the weekend and got it all together and what but it just blackscreened after about a minute after turning on, trying to boot into windows and bios, didnt change either way. I ended up leaving it on for about an hour, on the blackscreen, and now it doesnt even display anything, ive tried resetting the cmos, trying 1 ram stick, in different slots too, and putting the gpu in the other slot, also ive reseated the cpu which isnt much but whatever, everything is new apart from the gpu and cpu, the cpu is out of my old pc and it was working fine before, i bought the gpu off a guy and he said it hasnt been used, which it looks like it hasnt been but theres a bit of dust on the inside, unless one of the new parts i bought it fauly what could i be? And how could i trouble shoot without another pc to test parts in? also i bought an athlon 250 for $30 to try and it hasnt arrived yet. Any help is appreciated.

i only just saw about the screw extender things for the case, because before the mobo had alot of pressure and was bowing, would this cause the problem?
