Previously working pc have no video output now

[OliverHun]

So yesterday everything was fine , and good my computer freeze only 2 times when i used Fl Studio. But however i could restart my pc without any problem. So here is the thing! I was going to sleep after it and on the morning i tried to start my computer , but nothing happened . I was not even reaching the bios, the monitor was black , and sometimes its said there is no signal . Later i tried to fix this with my friend , i removed the battery from the mother board , took out the rams , change the video card to another slot but nothing worked. We was about to give up , and so i placed back the video card for one more time . And its worked! So i was happy everything was fine , be we still didn't knew what was the problem . Anyway at the night while i was playing my screen froze and i could not restart the pc . Same thing that happened before . I Changed the cpu to another one , and it worked fine with it . But then after i turned it off and on again i got blue death before i windows could load. Now i reinstalled my pc , and its works again but not with my Cpu. I don't know what to do now , so i ask for help here and i hope i will get the solution here , thanks for every help .

Videocard: Asus Ati r9270x
Motherboard: Asus m5a99fx pro r2.0

If system does not work with your CPU, sounds like a bad CPU. Although your post is a bit confusing about what you did and what is going on exactly. You swapped CPUs but it still crashed until you re-installed Windows correct? After that you tried your original CPU and it will not start at all, correct?

I mean i have an older video card , so i changed it to it . It worked with the old one but after somehow it freeze and after restarting , when i got to the windows logo the whole computer freeze and i got blue death. Now i reinstalled the windows , and its looks like working with it ,but still not with my normal video card.

So when you said you changed the "cpu" to another one you meant "GPU"?

What are the full system specs, power supply brand and model, what is the old video card model? Did you test the video card in another system to make sure it's good?

Sorry that i answer now , i had no time to get to my pc . i could not test it yet in other computer.
Here is the Specs:
CPU:OctalCore AMD FX-8320, 3700 MHz (18.5 x 200)
Motherboard:Asus M5A99FX Pro R2.0
Ram:Kingston HyperX KHX1600C9D3/4GX (8gb)
Gpu: ATI Radeon HD 4800 Series ( this is the one i use now )
Gpu: ATI Radeon r9270X (This is the one which is not working )
Psu: Coolermaster rs-600-acab-m2

The 270X should have about the same power draw as any of the the Radeon 4800 models, I'd suspect a bad card. Need to test it in another system and see how it runs. Power supply is not the best but not horrible, so that should be OK, at least I'd rule it out till you can see if the issue follows the card or not.
