OCCT CPU test - black screen

[Lucas_Oliveira]

I upgraded my PC recently, changing my Graphics card from a NVIDIA GTX 1050TI to a MSI XT 6650; to complete this gpu installation I reset my PC and after that this problem started to happen: it consists of my computer simply going into a black screen at random times while I’m using it, my monitor goes black like the PC shutted down but the tower and all my hardware inside remains on and running, like the monitor never even went black at all. It happened about 10 seconds after I turn my computer on and some apps start opening, when trying to open a game and mid-way when I’m playing a game… Whenever that happens, I press my power button from the tower for 5 seconds so my computer completely shuts off; and yes, I have tried to wait to see if anything in the monitor shows up back again after some time but nothing. I have even reseted my PC because I thought it was some game optimization in regedit I done or even overclocking but nothing seems to work. I also tried to check Event Viewer but it just says: “Event ID 41 - The system has rebooted without cleanly shutting down first.”

I then downloaded OCCT to run some tests and check what component was making the computer to “shut off”. I first ran the power stability test and the screen went black instantly after i clicked the start button. After that I was 99% sure it was the PSU, then I went ahead and bought a completely new one to test out and see (Gigabyte UD750GM) and tested again, the test ran for about 5 seconds and the screen went black again. After that I went ahead and tested different components, I ran the GPU test first and everything worked fine, I ran the memory test after that and everything worked fine, but when I ran the CPU test, the computer’s screen went black. So does that mean the problem is the CPU? And if it is, how would I fix it if there is a fix?

If there is anything I missed please inform me so I can reply.

Did you uninstall the old drivers then install the new ones for the display card.

If not then lets use DDU to get that done and see fi that helps at all.

Hey, so before I reset the pc I had uninstalled all the display drivers using that exact uninstaller you sent it to me, so unfortunately it did not work .

I also got some updates; I took one of my Ram sticks out the motherboard to test (because I have an odd number of ram sticks) and the OCCT CPU test worked perfectly, it ran for a long time and everything seemed fine and solved. However, when I was trying to open a game, the problem appeared back again and the screen went black. I then turned my PC off by holding the button for five seconds, went into OCCT and ran the power test this time, and the screen went black instantly after I pressed the green start button… So the tests that went through and were positive was for the CPU, GPU and MEMORY, the POWER test “turned my pc off” instantly.

Just to mention that I ran those tests without having a fully reset computer, I done some gaming optimizations in windows like putting the computer “High performance power plan mode” and others ( I’m just saying that because I’m not too sure how badly that can affect the tests )

What I’m thinking is that the problem might be the motherboard… I think this because every test but the power test works, and the power test puts load on the CPU ( which the individual stress test for it went positive ), GPU ( which the individual test for it also went positive ), PSU ( which is completely new so I don’t think there is any problem with it ) and the Motherboard ( which is the one left out from all of the working components ).

Please forget about the two last threads as I did some more testing right now and everything seems to be the same as it was when I posted the first thread . I ran the CPU test once again and the black screen came up after 15 seconds… So only the GPU and MEMORY are the components which are giving positive results and passing the tests, CPU and POWER are still giving black screen.

Sorry for lots of threads.

Let’s get a speccy report.

[COLOR=rgb(243, 121, 52)]Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

“High performance power plan mode”

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues, the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.[/COLOR]

Here it is: http://speccy.piriform.com/results/K...2jOAugt0j5XIyx

Model No. of PSU: GP-UD750GM

Also, I changed the power plan to balanced but unfortunately nothing changed, still crashed with black screen…

Will take a bit to go through the speccy report.

In the meantime do you have another user on that system that you can log into and see if this replicate.

Have you tried a Clean Boot on the system to see if this replicates.

Which slots are the RAM in?

[Lucas_Oliveira]

Hey, I don’t have another user to test it on the system, but I can create one if really needed.

Just tried the clean boot by following every step on the link you sent, opened OCCT, ran the power test and after 8 seconds the black screen came up once again.

Ram are taking up the first and second slot.

According to the manual the RAM needs to be in the A2 and B2

Other issues I see are the C drive is getting low on space.

Partition 1
Partition ID: Disk #1, Partition #1
Disk Letter: C:
File System: NTFS
Volume Serial Number: 12C85AF2
Size: 111 GB
Used Space: 82 GB (73%)
[COLOR=rgb(243, 121, 52)]Free Space: 29 GB (27%)

First issue I see is the drive is to small for windows to run properly and you are running out of space. Why we highly recommend a drive no smaller that 250 GB or more. This is because Windows requires on average 30% to 35% free space including 32 GB free space for updates, 7-10 GB reserved for future proofing on the C drive.

This is not including and limited to what the system uses for backups, swap page and hibernate files.

Lack of space will also cause file corruption and possible loss of data sine the drive will not be able to store the data.

One the above has been completed reboot and see how the system responds.

Use the system do not depend on some test to tell you.

[Lucas_Oliveira]

Placed the Ram on A2 and B2 and tried to open a game I was always having trouble to open it due to this problem and no good news, black screen.

I just freed some space by uninstalling one of the games I had installed in Disk C and also removed the restore point. Now instead 29GB of free space I have 67GB - tried to open the same game, it started, ran for less than 10 seconds and crashed again, black screen.

Something to notice, everytime the screen goes black after crashing the LED light of my botherboard lights up an orange light - maybe something to do with ram?

[Rustys]

No particular order and can and should be performed in combination with some you may have tried and not posted and some you may have posted and I for some reason not seeing it. So just to confirm…

NVIDIA GTX 1050TI to a MSI XT 6650

If you still have the old card may try that one again and see if it does the same.

Can defiantly run a stress test on the RAM which will require.

https://www.memtest86.com/

Is a program that I use you just need to have it preform several passes to get an accurate reading.
You should run for a minimal of 8 complete uninterrupted passes to get a proper reading.

Hey, I don’t have another user to test it on the system, but I can create one if really needed.

Lets create the new user see what happens.

Try a different Monitor.

Downgraded to a lower version of the driver for the ATI AMD Radeon RX 6650 XT card?

Tried a different cable?

Tried a different port on the card?

Lower the resolution setting?

Cleared the CMOS setting.
