My computer stopped working with seemingly no modification. When I boot up, LED and fans work but there is no beep or video.

After the issue surfaced, I performed all troubleshooting I could find here, even purchased a new motherboard and tried again.

-It worked 2 days ago. Prior to that the last physical modification was a new PSU and SSD install 3 months prior.
-It worked fine, I booted it down and it stopped working.
-Mother board is 5 years old.
-CPU is 1 year old
-No hardware or software installs were performed immediately prior.


SPECS:

CPU - AMD Phenom II X4 955 Black 3.2GHz Quad-Core Processor

Motherboard - 1) ASRock M3A770DE ATX AM3 Motherboard
2) ASRock 970M Pro3

RAM - 2x Corsair XMS3 DDR3
CPU cooler - Coolmaster Hyper 212 EVO

Video Card - Radeon R9 390 8Gb

Power Supply - EVGA 600B

Hard drive(s) - 1) 850 EVO SSD 500GB
2) Seagate 1.5TB

Operating System - Windows 10 Pro 64

Steps I've taken

1. I've read through and followed this thread with no success.
2. I tried unplugging Fans, LEDS, HDD SSD, disk drive, etc.. No success.
3. I tried removing GPU
4. I tried removing Ram, received the "no Ram" beeps (three short beeps I beleive). This confirmed that the speaker works. I tried moving ram around and trying each stick individually but there were no beeps.
5. I completely swapped to a brand new motherboard and get all the same symptoms No difference between the two motherboards.
6. I have it plugged into a watt meter... It's running at 70-80 Watt powered up.

Starting to think CPU because the power usage is low and I can't hear it. Any guidance helps.

What I meant to tell you is just took out the motherboard out from the case. And power it on with CPU,RAM,HDD and no GPU. If you get success then add the GPU later on and try again. The thing is you just removed the case that's the point.

Remove the CMOS battery and wait for 10 mins then put it back and turn on the PC.

I tried each ram individually, in each slot, no beeps. When I remove the Ram completely I hear 3 beeps. As the steps in the linked thread recommend, I tried removing each component to the point where I just have CPU, PSU, the speaker, motherboard and Ram. Neither motherboard works. Could it be the CPU?

Its clear the RAM is good as you get beeps when you remove it. Sadly it could be the CPU, verify the 4+4 EPS 12V is connected properly.

Your motherboard supports Socket AM3+ / AM3 so if you have any unused working AM3/AM3+ CPU, use it in the motherboard to ensure the problem is the CPU.

From what I've read on similar problems on this site, these symptoms either mean CPU or motherboard. Since I've completely replaced the motherboard with no success, I'm trying a CPU (should arrive mid next-week).

You won't be able to get to the BIOS without a working CPU.

Update on this as I'm still having the issue.

Local repair shop told me that my CPU heatsink was too tight. After taking it home and loosening it completely, it still didn't work. Finally I moved my GPU to the x4 slot and removed and readded my CPU and it worked. This continued to work for another 4-5 days and now the issue is back. I went through all the steps listed above again.

Interesting side note, not sure if related: I had 4-5 different memory failures while it was working. Eventually I moved both sticks of RAM into slot 1 and 2 (they were in 2 and 4 then 1 and 3 before this) and it carried on for 2 days without issue.

I switched back to CPU 1 and it worked with no real explanation. Out of fear of repeating the issue, I've left my computer on for a week with no issues. I just restarted it and I'm back to square one.

It's interesting that it'll run fine, but won't even post after a reboot. I've messed with everything again and can't get it to come to again.

Anybody have any other suggestions?

I had the same exact problem not too long ago. I had a failing HDD (which I still have, but I'm scraping by with it) which would try to boot, and would black screen. Unplug/check the cables. It could also be the RAM. Try reseating the DIMMS.

Thanks for the reply, I forgot to respond. I don't think it's HDD because I have 2, and have tried switching to each one separately. I also have 2 different sets of RAM I've tried cycling between without any success.

At this point, I'm 2 months in and still don't know 100% what causes my issue. Here's an update;

I ran my computer for 2 weeks straight without powering off without any hick-ups. As soon as I need to reboot, the issue comes back. It typically takes 1-2 hours of fiddling before I can turn it on. The only thing that has been successful with the fiddling is removing the CPU fan and putting it back. It's not a heat issue, because my CPU is super cool and during the 2 weeks I ran the CPU usage to max without issues. If the computer is running and I apply pressure to the CPU fan, it powers off.

After swapping my CPU back to the old, I didn't notice any change. My guess at this point is my MB may be touching my case when pressure is applied by the CPU fan (or me). 2 of the CPU fan mount nuts are touching my case, perhaps a grounding/shorting issue? I don't have another case or breadboard to test this but before I go down this path, can anybody validate that this can happen?

it might have chances.take your mobo out of the case and place on a flat surface no need of case. check it if u are facing same issues.place the mobo gently on the surface pressing the mobo will make the solder pins bent below the mobo.

I've had this MB for a number of years, and this issue has presented itself across several different video cards. The following procedure yields positive results each time.

1. Turn off case power.
2. Remove monitor connector from vid card.
3. open case, remove power cords from vid card.
4. remove vid card
5. reinsert vid card.
6. plug everything back in, and power up.

Works every time. My bet is the reason anbu13 solution worked was it also called for removing the video card.

Point of note, there are deviations from this procedure that will sometimes yield positive results and sometimes not. One I do not recommend, is to power down, remove case power cord, hold the start button for one minute, and power system back up. This will solve your issue, 90 percent of the time, 9 percent of the time your will need to result to the previous procedure, and one percent of the time your power supply will LITERALLY EXPLODE, with sparks, bright lights, smoke, and the nifty smells of vaporized metal.

You can skip some of the steps in the first procedure and perhaps get desirable results, but I wouldnt recommend it.
I have been wondering if this was a graphics card issue, or a MB issue, and from the collaboration here it seems its a MB issue. I beileive there is a static charge that developes on the PCI port.
