No video on pc boot, fans running

[Cadeauken]

(Backstory, skip to next brackets for troubleshooting info) Hello, i am a very new builder, and prior to my assembly of this pc i need help with, my gaming set up was a ~$500 pre built dell desktop with an i3 4150, 8gb of ddr3 ram, a 1tb hdd, dell 300w psu, and a gtx 750ti slapped in there for power. Recently, i decided to buy a case, new motherboard, and psu for upgradability of this machine. I bought an atx tower by rosewill, 500w evga psu, and an msi mini atx (i believe ?) ddr3 mobo. I watched tutorials to help me put it all together and, after a bit of confusion with accidentally misplacing the jumpers, i had success! The pc was up and running like normal after some getting warmed up. 

[heres where the problems start] 

However, this morning i opened up star wars jedi knight jedi outcast to play and after a bit left it running to go play xbox downstairs with a friend, upon returning i had a blue screen! Odd especiallyl considering how unintensive the game was. Since the "report" to ms was not loading (0%) i turned the computer off and on again to find no video on my monitors, but all fans running (3 case fans, cpu cooler, gpu, psu, all running) i did extensive researching all day today and tried EVERYTHING i could thus far (resetting cmos, changing ram, reapplying cpu in case there was some loose thermal paste, trying my old motherboard, unplugging hdd to see if it is corrupted) to absolutely no avail. Any advice? Could this be my cpu, psu, or motherboard? And how could i fix it? Thanks in advance for reading all of this and trying to help. If you need any more info ask and i can try to supply

UPDATE: I put my computer back in its original shoddy dell case and tried out its 300w power supply, a yellow light came on FINALLY giving me some sort of information, the case looks like this, any ideas?

I tried booting with jumpers missing on one of the 3 pronged usb pins, but then placed them on 2 of the pins and it booted fine into windows
