Hello Forum People!

I'll just dive right in. My computer was not recently built. Original build was 2011, but it has had the motherboard, RAM, and video card updated more recently. Most recent was the graphics card and RAM, but that was close to a year ago. As of yesterday (Monday, 1/09/2017) it was working fine with videogames, Facebook, etc. Today it won't turn on.

Today I tried turning on my computer multiple times. Every time the same thing happened...
1) Motherboard Logo appears
2) Windows 7 logo appears and begins loading
3) Windows 7 logo disappears, monitor loses signal, and my screen is just black until I reset.

I did some searching on the Forums already and have tried the following...

1) I turned on the computer in SAFE MODE WITH NETWORKING. The computer booted correctly. I still had my cable connected to the video card while doing this, so on-board graphics were running through my video card to my display.

2) My cards last driver update was in the middle of December. I tried looking for a newer one, but it was up to date.

3) I rolled back the driver to September and restarted my computer. No change, it just went to a black screen again.

4) I completely uninstalled my video card and restarted. The computer booted up fine using the motherboard's graphics. Once booted it asked to download and install the video card's drivers. Once installed I rebooted again but I saw no change, just a black screen.
*********
I feel like this is a hardware problem. I'm going to try cleaning and reseating everything when I get home tonight (currently at work) and see if that helps. If it doesn't, I'm suspecting that either my Motherboard, video card, or PSU has crapped out on me (is 6 years old for a PSU?). Could RAM be the cause of this? I'm having a hard time believing that this is software related. Any help on this is much appreciated!


Thanks!

What are the specs for this system? In particular, we need the make/model of the CPU, motherboard, video card, and power supply. Need to know how much memory, what storage devices and whether you are overclocking anything (CPU, GPU, memory). This will get us started.

Oops, I misspoke earlier. I said the computer booted with motherboard's graphics... that was false. I thought it was doing that, but actually when I booted in safe mode I was still connected to my GPU. Turns out my motherboard, ASUS Sabertooth 990fx, does not have an on board video card.

COLGeek: I don't have all the specs in front of me and I'm afraid that if I try to recall then I'll get something wrong. Later tonight I'll be able to give the system specs.

SgtScream: I have trouble believing that, considering that I was running this graphics card for close to a year without anything going wrong, and I believe that I uninstalled my old GPU drivers when I physically replaced it. I'll double-check this.

Ok, Here are the specs and how long I've had each component. The GPU was put in back in March of last year. The RAM was in January of 2016.

2011 - CPU: AMD Phenom II X4 955 Black Edition Quad Core 3.2 GHz
2013 - Mobo: Asus TUF Sabertooth 990FX R2.01600 MHz - 16GB total
2011 - PSU: Corsair 750TX
2011 - HDD: Samsung Spinpoint F3 1TB
2016 - GPU: MSI R9 390X
2016 - RAM: Two sets of Corsair Vengeance 8GB (2X4GB) DDR3

This morning I plugged the GPU into my second PCI slot and booted the PC. Once booted it installed driver files and asked for me to restart but there was no change once it did. The monitor showed the motherboard logo, and then that it was loading Windows, then it lost the signal.

My next step is to borrow a friends GPU and try it. My thoughts are that either the video card is bad, or my motherboard is bad, so if I can boot, install drivers, and run off a different video card then maybe I need to look up the warranty information on the card.

I would suspect the old PSU more than anything else. I suspect it is failing under load when the full capability of the GPU is enabled by the video drivers (the standard VGA driver used, like during Safe Mode operations, requires less power as fewer features are used).

So from what you all are saying, either power supply or video card. I have a 3 year warranty on the card, so that's no big deal. I have also wanted to purchase a new modular power supply unit, because right now I have cords everywhere in my case and I hate it. Haha

Anyway, I just remembered something that had been happening but I never worried much about. I've been playing games before that in the middle of an online match the screen will just freeze up for a second, maybe two, and then recover from 0 FPS back up to 60 (it's capped). By freeze, I mean mouse won't move or anything and the speakers let out a painful, backfeed-like sound. I mentioned this to a friend and they thought it sounded like PSU getting overloaded. His statement was that the maximum wattage of a PSU can degrade, so that maybe my 750 was barely performing well enough for a while, but now needs replaced.

To check my usage I went to Newegg and used the Power Supply Calculator. Putting in my system specs it told me that I require 794 Watts! So at this moment I think I'm going to purchase a larger PSU and see if that solves my problem. I had never realized that my GPU requires 500 watts at full performance. For crossfire I require a PSU of 1000 Watts so I'm going to purchase a 1200 Watt PSU for the extra breathing room and see if that fixes this issue.

I was facing the same problem with HDMI port of GTX 1050 TI.
Solution that worked for me was to uninstall the NVIDIA driver using the tool available at
http://www.guru3d.com/files-details/display-driver-unin....

Install the latest Nvidia Driver from www.geforce.com. (Please note unintall driver is required,simple reinstall will not work.)
I hope it helps;

Hey guys, been a while since I updated last. Took almost 3 months for MSI to fix and send back my videocard, but I have no idea what they fixed because it still isn't working. My friends Sapphire card worked upon initial boot, but when the computer installed the drivers for my friends card it ended up doing the exact same thing, losing signal after the windows logo.

Now I'm suspecting the hard drive, and am about to buy a sold state to upgrade/fix the problem. Any thoughts? What else could cause this, the mobo? Seems like new data trying to run the videocard at optimum settings is what's causing the loss in signal, just don't know why. :(

Another update:
I updated my BIOS, which didn't help, then decided to reinstall Windows 7. The reinstall wiped all the drivers, so starting from scratch I updated all of the mobo drivers. I was able to browse Internet for whatever I needed, watch videos, etc. Then I updated the video cards drivers and the issue was back. Side note, my speakers were on when the loss of signal happened and I heard the logging in Windows sound, the one that plays when your desktop loads.

So w/e the problem is, it seems like it only hapens when the video card is trying to actually perform at optimum settings. I now have that 1200 watt psu, so it's definitely got the juice. Could my motherboard or cpu not be able to handle the card? I'm so stumped.

I just got the card back from MSI's RMA process, and the issue was still there. I also tried my buddies card, a sapphire nitro, and it booted up fine, but once drivers got installed it lost signal as well. I think something is breaking once the video cards are trying to flex their muscles.

Ok, so another update. :/

I bought a new cpu, one compatible with my mobo, amd brand to match the the videocard, slapped in the new ssd hard drive that I just got in, and I installed windows 10 from fresh. Once 10 was installed and I got to my desktop I ended up losing signal again. BIOS is correct for my cpu and there is nothing but the operating system installed.

Motherboard is bad?

I went ahead and double-checked my RAM last night. I have 4X 4Gb sticks of 1600 corsair vengeance. I mentally labeled them 1, 2, 3, and 4, and did configurations of 2 at a time (1, 2... 1, 3..... 1, 4.... 2, 3..etc.). None of the combinations made a difference.

I do not believe it is a power supply issue. Computer worked fine with the old one, but now I have the 1200 Watt power supply, which is powerful enough to run crossfire with 2X R9 390X.

I've been doing a hell of a lot of online searching and found that a lot of people are having the same issue with Windows / Nvidia builds. Seems like people believe there is some compatibility issue that occurred during a recent Windows update. I have no idea, I'm just about defeated with trying to use this AMD build. I wish I had just upgraded into an i5 build.

To summarize, what I've changed out is PSU, Mobo, CPU, Hard Drive, Monitor, and GPU. Now that I've checked the RAM and found no issues with it, I have nothing left that could be faulty.

Well, I had mentioned that I tried another monitor and had the same results, right? Well the constant was my DVI cable. I changed it out and the problem went away. Didn't know those could go bad, especially after only a few months. Thanks for all the help guys.
