I upgraded my CPU and GPU - Now my computer goes to "sleeping mode"/black screen after launch

Hi forum.

I've just bought a new CPU and GPU, and since I installed them, my computer hasn't been able to start up without the screen turning black and mouse shutting off etc. after 2-5 minutes on desktop. (Computer doesn't literally turn off - fans still running)

I've been trying to fix this issue for 2 days straight now, and have almost come to the conceding point. Here are my newest specs:

Operating system:
Windows 2.6.1.7601 (Service Pack 1) 64-bit

System:
MSI

System model:
MS-7641

BIOS:
760GM-P23 (FX)

Processor:
AMD FX(tm)-8350 Eight-Core Processor (8CPUs), -4.0GHz

Memory:
8192 MB RAM

Graphics card:
ASUS Geforce GTX 760

Power supply
550W

What I can conclude so far:

- My motherboard does support my newest CPU. (http://www.cpu-upgrade.com/mb-MSI/760GM-P23_(FX).html)
- My drivers are updated. Still not working...
- My BIOS has been updated through LiveUpdate5. Still not working...
- I've checked my CPU temperature through TempCore, and at 50C it turns off, so I don't think its due to overheating. BUT sometimes, in TempCore, it starts to bug and for some reason the program tells me that the temperature has reached 200C... Shortly after it tells me that, my screen turns black.

  1. The link you posted is broken, and this is an official list of supported CPUs: http://www.msi.com/product/mb/760GMP23_FX.html#/?div=CPUSupport

    Your CPU model is not listed.

    Ooooh....
    So my problem simply lies on the fact that my motherboard isn't compatible with my new CPU?
    If so, I guess I'll just get a new one that works with it ;-)
    Any good recommendations?
  3. Yeah, just pick another FX, maybe the FX-8300 and you will be fine.
  4. Thank you so much!!
    Ill get a new motherboard.
  5. After looking at your CPU support list, it does seem that your motherboard does not support your current CPU; hence why wrong temperature readings are being presented. However, I believe there maybe another solution to your issue. If you see the startup logo showing "Starting Windows," then perhaps your GPU is also raising issues.

    I believe the problem occurs due to your GPU, alongside your CPU perhaps. Boot into safe mode (if you can't, take out your GPU and try then) and uninstall your previous GPU drivers via Device Manager + Control Panel, or Driver Sweeper (uninstall your old graphics card drivers). Then restart, and you should be able to boot with your new GPU.

    All the best.
