[SOLVED] New graphics card no display

[Heavy Pootis]

I just bought a rx 470 and it showed no display when connected to DVI and HDMI port. One of the ram slots is also broken. I think I need to buy a new motherboard. What motherboard is the cheapest and best motherboard for 2nd generation Intel processor. I've also checked it on other monitor and still no signal and when I installed the graphics card into the motherboard and connect it to the integrated graphics of the motherboard still no signal. I've also disabled the intel graphics driver.

My specs:
Intel Core i7 2600 3.4 Ghz
4 gb ram
rx 470
Thermaltake 450 watt psu
500 GB HDD
120 GB SSD
powerspec b670 motherboard

I had a GTX 950 2GB. I was using that graphics card for a long time and one day the computer froze with the display still showing. I restarted the computer and then no display. I checked my RAM, but still no display then I removed my graphics card and the computer booted up just fine. Then I bought an RX 470. I thought that the graphics card was faulty(GTX 950). But the RX 470 did not work. I checked the RX 470 on another computer it worked fine. I think that my PCI express slot is broken. Can a PCI express slot be repaired?

My specs:

Intel Core i7 2600 3.4Ghz
8 GB ram
Thermaltake litepower 450 W PSU
120 GB Gigabyte SSD
500 GB WD HDD
power spec b670 motherboard

I also think that my PSU is not good enough to run this card.
