[SOLVED] [SOLVED] No video signal. New GPU and new motherboard.

[Otirik]

Ok, I'm at my absolute wits end with this <mod edit>. I'm about two seconds away from tossing my tower out of my apartment window.

Specs:

Amd a10 quad-core 3.4ghz

Old gpu: Saphire Nitro R9390

New gpu: Amd Radeon Rx590

24 gigs ram. 8g x 3.

This all started when I recently purchased a brand new OON 4k 50" tv at Walmart. My old monitor works fine, but had the resolution of a potatoe. 1024x768

I swapped out TV's, messed around with the resolution and refresh rates until I got it to how I wanted it. 1920x1080 @ 60hz.

Everything worked perfectly. No glitches, issues, etc. The next day, I boot it up to play some Rainbow six seige. Played for a bit until I got hungry, went to the kitchen to get a snack, then when I returned I got something weird. My tv was flashing "No signal". I thought it went to sleep, nope, thought it was a glitch or something. I unplugged the HDMI after manually shutting off both the tv and PC. Let it sit for 10 minutes, plugged it all back together and " Wow ok it worked."

I soon after went to bed none the wiser. Woke up, today, did some stuff, then attempted to play more videa. Started everything up. No signal. Tried the same method again. Did NOT work this time.

-I tried a different cable. Nope.
-I tried a different powerup sequence. Nope.
-I tried a different hdmi tv port. Nope.
-I tried removing my GPU and starting the PC through the CPU integrated graphics. Nope.
-I tried leaving everything unplugged for an hour with the cmos battery out. Nope.
-I tried swapping out the motherboard from a donor PC that had the same board. Nope.
-I tried replacing the GPU with an upgrade I ran to buy at BestBuy. Nope.
-I repeated this entire sequence on my OLD monitor! Nope.

So far the parts I have replaced are the GPU, motherboard, HDMI cables, CPU, psu. If anyone has any advice or tips please help a fellow out. Im so done with this I'm like borderline about to go postal.

Thanks again.

make and model of the psu?
return the gpu and get a lower watt one

Corsair cx750m it's 750 watts.

The CX is entry level for Corsair, thus the circuity is basic/cheap. Could indeed be a faulty or failing unit, 750W or not.

Im willing to try anything at this point. I'll go grab another PSU right away. Thanks for the tip.

It's just a thought, no guarantee at this point. You mentioned another board and GPU already though. When signal is lost, is PC staying on? Old monitor working now?

Ok so, Currently I'm at BestBuy picking out a PSU. After I made this thread I had officially tried 3 different monitors. Thats pretty much ruled out at this point. As far as what the PC does when I power it up...it runs exactly how it did before when it was working. No beeps, already confirmed that the motherboard is capable of beeping. The PC turns on, fans come on, not loudly or at max mind you, nothing out of the ordinary. Just no signal to the tv/ monitor.

Hmm, has the CPU itself been swapped?

Yes, technically. I pulled a donor motherboard with the CPU already attached. Same parts as the ones I had installed before.

Also I installed a new Evga 1000 watt PSU. It did not help unfortunately.

Have you troubleshoot ram? Try one stick, try them all separately.

Could be each time you were away from the computer it bsod'd then tried to restart and then proceed no further. Crook ram(s) can do that. Or even just placing all three in alternating slots can help. But yeah, check your ram.

 

[boju]

What motherboard do you have? And do you know the order of dimm slots?

 

[1LiquidPC]

OK. What all parts have been swapped so far, or what's left that's common? Does "breadboarding" work? Possible a case short of some kind, a bad HDD/SSD causing short(think I saw on Jayztwocents one time), or faulty RAM?

OMG. WOOOOOOOOOW.

It was the fricking ram all along. I had a bad stick this whole time. What a bunch of baloney. I pulled out one at a time, starting my PC everytime I yoinked one, did it until the issue resolved itself and I had one stick left in there. I did the exact opposite by inserting a stick, starting the PC then inserted the last one, LOL STOPPED WORKING!

I really appreciate and thank you for the tip and taking the time to help me out. Kudos.

Dude I finally got it. It was bad ram all along. Boju helped me with that. What a dumb and irregular way to cause a no signal issue.

I really appreciate your help, and I suppose it's not all bad, considering now I have a fully upgraded gaming rig. Thanks for the assistance and your time. Kudos.

Glad to hear the news. Yes indeed, a faulty module can cause a no POST issue. I went back through your list and now see RAM wasn't changed throughout other testing. Might be worth running Memtest86 on remaining modules just to be sure. Slots can fail as well, though rare. Worked on an MSI Z97 based board about a year ago and that was the cause.
