My computer as usual. Two days later I turned it on, and got no display. When I looked inside, the fans on my gpu weren't spinning. Everything else seemed to be fine, the lights came on, the inside fans were spinning, etc. I have tried a replacement for every part. I ordered a mobo and used that to no avail.
My motherboard was an MSI 970A-G43, is now an ASUS M5A78L-M Plus USB3. I have not used the instal cd for it yet, if that will make a difference. My pc doesn't have a cd drive, so I was going to use a USB drive.
Graphics card is a Radeon R7 370
RAM is 2 8GB Ripjaws
PSU is a CX500
Processor is AMD FX-4350

Hello Zgw00,

 

When I looked inside, the fans on my gpu weren't spinning. 

 

 

Couple of questions if I may;

 

Was the supplemental six pin power dongle from the PSU securely connected to the R7 370 GPU.

 

Have you tried completely removing the R7 370 GPU from the motherboard and connecting the screen to one of the video ports on the ASUS MB.

The cord from the PSU to the R7 was secure. Wasnt touched until after it stopped working.
I did try both hdmi and VGA on the board itself and still got a "No Signal" from the monitor. I didn't take the GPU out when trying this though, if that makes a difference.

The add on video card must be physically removed from the MB or the BIOS** will detect the add on video card and disable the onboard graphics, this whether the add on video card is working or not.

 

** NB: Some MBs will allow the settings to be changed in the BIOS to alter this but it does require the end user to change this and it is not done automatically.

 

Remove the R7, try the onboard graphics then get back to us if you will.

I realize now that I forgot to try different stick of RAM. I'm going to try and borrow a replacement stick from a friend in the upcoming days.
I will get back to you later on the On-board graphics when I try it.

If you try removing the R7 as suggested you may find that you have no need to try borrowing additional RAM.

New ram didn't work either.
When I tried the onboard graphics, the computer made noise like it booted up, and the fans whired but only for a second before it powered off. Pressing the power switch again gave nothing, until I turned off the power switch in back and pulled out the power cord then replaced it.

 What happened after pulled and replaced the power cord and was this with the add on video card removed.

After plugging the power cord back in, pressing the power button yielded the same result of turning on for just a second then shutting off. This was with the R7 removed.

Thanks for confirming  :thumbup2:

 

Try restarting with the add on video card removed and no RAM in the slots either.

 

If the behaviour is the same (powering back down) we should look at doing a quick check on the PSU.

I put my original motherboard back in the PC, since the new mobo didn't change anything.
The thing I'm having trouble understand is how a solution hasn't been found if every single part has been replaced. Is there something I'm missing? Even the HDMI cord has been changed, the monitor works for sure, vga didn't work either.
Isn't one of the only possibilities faulty replacement parts?

Sorry can`t really comment on that as you never got back to us with a response to what was suggested in my reply #10.

So, it's been over a month now since my computer stopped working, and I still have no luck. I didn't try your solution in number 10, as I put the old motherboard back in the Pc, and that mobo doesn't have integrated graphics. You also mentioned it could be a PSU issue, but I've tried a replacement PSU already. Could the replacement have been faulty? If I have replaced every part could it be a combination of parts?
Do you think getting with someone who has a pc and just swapping parts until something happens would be a good idea?

If you have replaced every part to no avail, then the only remaining possibilities are - some of the replacements are indeed faulty, there is some sort of compatibility issue (seems unlikely though on a previously working system), or maybe user error - like something not connected that should be.

 

Have you tried another CPU?  If you've changed every part, I'm guessing you have?  Failures are very rare, but not impossible. 

 

You tried another PSU - was it known good pre-used, or brand new?  Reputable brand or cheap generic?  

 

If you have a friend with a similar computer setup (or a second computer yourself) you may be able to check some of the parts, like the video card, work in another (working) system.  Going back to your post which sounded the most promising :

 

New ram didn't work either.
When I tried the onboard graphics, the computer made noise like it booted up, and the fans whired but only for a second before it powered off. Pressing the power switch again gave nothing, until I turned off the power switch in back and pulled out the power cord then replaced it.

 

It may have been helpful to try resetting the BIOS at this point to restore factory defaults.  Not saying it would have worked, but it's something that occasionally gets you out of a hole when a system fails to boot.

A Couple of question to straight some confusion 
Prior to the time your PC is not giving display, 
did your pc just randomly rebooted or tuned off so you had to turn it back manually?

When you say Computer giving no display - Did Monitor show some sort of signs saying "No signal?" or was it just pitch black(with Monitor power turned on ofc)

Did you install new GPU when PC was not giving u any output?
