Random PC freezes

I run the SFC /SCANNOW Command - System File Checker and the message i got was Windows Resource Protection did not find any integrity violations. I am going to test the directx now

I checked the Diagnosing basic problems with DirectX and it gave me no error. a also reinstalled the nvidia drivers following your instructions but i am still getting black screen when running diablo 3. Can you give me more information on how to run some diagnostics with Unigine: real-time 3D engine (game, simulation, visualization and VR) ?

i am also posting a rar with the temperatures while the crash and black screen occured

The health report by itself is not too helpful. First, please post back whether you uninstalled and re-installed the graphics drivers using the steps in my previous post. Second, please follow the https://www.sevenforums.com/crashes-d...tructions.html to provide us with your system event viewer logs. Those logs will help with the black screen crashes.

i have uninstalled and reinstalled the graphics drivers as you told me to. i am also posting the bsod log

You have a hard disk controller driver error. Uninstall the driver and then let Windows re-install it. You should find it under IDE ATA/ATAPI controllers.

1. Click Start Menu
2. Right Click My Computer/Computer
3. Click Manage
4. Click Device Manager from the list on the left
5. Find the device you are trying to uninstall by expanding the appropriate set of devices
6. Right click the device
7. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
8. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
9. Restart your computer.

Alternatively:

1. Login as an adminstrative user.
2. Click Start Menu
3. Click Control Panel
4. Click Hardware and Sound
5. Click Device Manager (the last link under Devices and Printers)
6. Find the device you are trying to uninstall by expanding the appropriate set of devices
7. Right click the device
8. Click Uninstall (do not click OK in the dialog box that pops up after hitting Uninstall)
9. Put a tick in Delete driver software for this device (if this option is available, otherwise just hit OK) and hit OK
10. Restart your computer.

good morning. i followed your instructions and i uninstalled the hard disk controller driver, then restarted and let windows reinstall it. Under the IDE ATA/ATAPI controllers there listed 3 ATA Channel 0, 3 ATA channel 1 and 3 Standard Dual Channel PCI IDE Controller, i uninstalled all of them.

So after i did this it seemed that the problem was fixed, i passed the login page in diablo 3 which always caused a black screen. But after some time i got a black screen while i was switching tabs in google chrome. I uninstalled and reinstalled the drivers but i still get black screens.

The black screens have occured so far while i was doing these things : After logging in in diablo 3, while switching or opening new tabs in google chrome or firefox, while opening a msn tab to see a message, while using skype and when i tried to play League of Legends.

What should i do next?

Can you describe what happens when it black screens? Does the system still seem to be running, there is just no video? How often does sound stop? How often does sound continue playing?

Would it be possible for you to borrow a friend's graphics card or use a spare card you might have to test the system? Could you do the same with a PSU? Try to get components that are similarly rated to yours.


Do you have any problems with the DX11 benchmark from Unigine? What about the Tropics and Sanctuary demos?

The system sometimes stops working when the blackscreen occures, and sometimes it works for a maximum of 30 seconds after the black screen. For example when the black screen occured when i had windows media player running, i listened to the song playing for about 10-15 seconds until it stopped. Another time when i was using skype, i got a black screen and the person i was talking to was able to see me for about 20-30 seconds after it happened and then it crashed.

Usually the sound continues to play for some second after the black screen. On ther other hand, when i got a black screen on a game, i could hear the music of the intro for some seconds, but when i pushed alt-tab, alt f4 and ctrl-alt-del the system wasnt responding and the music of the intro continued to play.

Unfortunately none of my friends or i have some spare graphic's card or PSU.

Also i never got a black out when my pc was idle. I left my pc running through the night with some programms that i usually use open and it was alright. But in the morning when i used my pc i got a black screen.

Can you give me some more details for the Unigine? What should i download and how can i test it?

Thanks in advance.

Strip down your system to run only the bare essentials: one RAM module, the CPU, motherboard, one hard disk, one graphics card (or use onboard graphics if you have it), keyboard, mouse, and one monitor. See how the system behaves by running Windows for twice as long as it typically takes for you to get a crash. If it is stable, add one piece of hardware back at a time until you get crashes again. Take notes of what hardware you add and how the system responds to the hardware changes.

As you add and remove hardware, follow these steps for ESD safety:

1. Shut down and turn off your computer.
2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.

Once these steps have been followed, it is safe to remove and replace components within your computer.
