Is there a black screen after the last update?
Is there a black screen after the last update?
Hi!
I just finished formatting my disk and fresh installed Windows 11. Everything seemed normal until I restarted the computer to apply the latest update. After installation, I accessed the log screen, entered my password, and then encountered a black screen. The cursor was visible but everything else was black. I tried common commands like ctrl+alt+del and alt+F4, but nothing resolved the issue. Eventually, I powered off the PC and pressed the reset button, but when I tried to boot, neither the ASUS display nor the log screen appeared, only a black screen remained. I also tested connecting another monitor, which still didn’t help. I attempted the Winkey+ctrl+shift+B key combination to reset the graphics driver, but it didn’t work either. Is there anything I can do? Did the update damage my PC?
🙁
Any assistance would be greatly appreciated.
Is there any need to enter Safe Mode? I was wondering about recreating your bootable USB installer before reinstalling the OS. Should I have disconnected all drives except the one for installation? Did you turn off X.M.P/D.O.C.P in BIOS before the installation?
I will attempt to do it again later, but until now I wasn't able to enter Safe Mode—it just showed a black screen. I’m not sure what that means, but I believe I didn’t reinstall my bootable USB before the OS install. I disconnected all drives except one, and the BIOS was set to default (no XMP) both before and after the installation.
Edit:
So... The computer suddenly worked again. I plugged it in, turned it on after a few hours, unplugged it, and it functioned properly... I’m relieved it did, but I’m still concerned something might be wrong with the machine :/
I would search for a malfunctioning power supply. With a reliable motherboard and reputable power supply provider, the power supply will send a signal to the motherboard confirming the power is functioning properly. If an incorrect signal is detected, the motherboard won’t boot until it receives the right signal, resulting in a blank screen.
Occasionally, a simple power cycle can restore functionality. If possible, try booting into BIOS to verify voltage readings and ensure they fall within acceptable ranges (generally 5 to 10% of specifications) for 3.3V, 5V, and 12V.
Also, check the system clock time in BIOS to confirm it remains accurate. Sometimes, battery backup systems on the motherboard may begin to fail, leading to loss of BIOS settings.
Another potential issue involves overclocking software. You can download and execute microsoft autoruns64.exe to remove outdated overclock drivers. This occurs when Microsoft updates a driver but older overclock or BIOS versions remain installed that require updating as well.
So the PC was functioning properly until it stopped working completely. Yesterday I began downloading and installing a video game. About thirty minutes later, when I returned to check the progress, the screen went black again. This happened the same way on Wednesday. I attempted several fixes: rebooting, power cycling the PSU, performing a hard reset of the BIOS, using an older set of RAM, trying to boot by unplugging one SSD at a time, and even leaving the PC unplugged for several hours after the last failure. Each time it would start working unexpectedly, but never fully. The PC still boots, yet it only displays a black screen, as if it didn’t receive any signal. Recently, I purchased a new PSU because I experienced issues a few weeks ago—specifically, trying to XMP a new RAM set and dealing with a faulty drive. Here’s the situation: [SOLVED] - Can't access BIOS after a hard reset? I recently replaced my RAM modules (second-hand) and installed them. Initially, everything worked smoothly. My motherboard has a default RAM speed limit of 2666 MHz. The new RAM I bought is a Lexar THOR 32 GB DDR4-3200 CL16, so I considered enabling XMP in the BIOS to... forums. I suspect the PSU might not be the issue now. However, I remain concerned. Given my past problems and the fact that I attempted overclocking without updating the BIOS, and considering I plan to upgrade my motherboard or graphics card (RX 6600, still under three years), there’s a risk I could have damaged something important. My current build is still awaiting an upgrade to the Ryzen 5700X. Here’s the link to my setup: https://de.pcpartpicker.com/list/f629h7
Generally, when I encounter a black screen, I consider power issues first. It isn't always the power supply itself, but could be an incorrectly connected connector from the power supply to the GPU. You might want to examine the connector and verify all pins are properly attached. If not, the GPU may draw excessive power from the PCI/E bus, activating motherboard protection circuits that prevent the CPU from starting, resulting in a blank display.
Also, inspect any power connections from the motherboard to the CPU for supplemental power and confirm they are secure.
Can the machine boot into BIOS and run stably?
(Updated BIOS with default settings, no overclocking on the PCI/E bus)
Beta BIOS includes a fix for TPM firmware issues
I checked yesterday all connections to the PSU, and they were fine, but I still replugged all of them. I also tried connecting the graphics card to the other PCI connector, but same result, the screen cycling between HDMI and Analog without getting a proper signal until it goes black.
I boot into bios because I don't see anything on my screen. I did update the BIOS with the last non-beta ASUS B450-Plus version and had the default settings, no overclock, and it was stable until the first black screen happened. I've tried all I could think of but I still get the same result, so I think I may bring the computer to a repair shop to know what is the problem. A this point I wouldn't mind if it's the mainboard and get a new one (mine is old enough), or a newer and better 2nd hand, but I just hope it isn't the graphics card, because that would be an investment I cannot afford now
🙁
Thanks for trying to help though!
Hi, just a suggestion, maybe a motherboard reset may help. Shut down the PC switch off the PSU disconnect the power cable from the PSU remove the CMOS battery and press the power button for about a minute to completely discharge the motherboard. Give it a few minutes, then replace the CMOS battery reconnect the power cable to the PSU switch on the PSU and try to boot the PC. See if you are able to get to the BIOS screen. Please post your results if you decide to try this, maybe on a working PC if your PC fails to boot to the BIOS. There are people here who can help you with further diagnostics.
Hi! I also attempted that before taking my computer to a repair shop, but it didn't work. The shop said the PSU was bad... I wasn't expecting that since I bought it a month ago. Now I installed my old PSU while returning the faulty one, and everything is working again. Thanks everyone for your advice and support!
Another update in this ongoing situation. The PC kept working until I restarted it, but then a black screen appeared again. This time, I could hear Windows boot up and enter the sign-in screen (though I wasn’t sure it was happening before I took the PC to the repair shop), but there was no display. I brought it back to the shop, thinking it was still a hardware issue, only to find out it was a Windows update. After resetting the PC several times, it worked again...
This experience of encountering a black screen after a Windows update wasn’t something I’d faced before on Windows 10, but it began after I upgraded to Windows 11 (after formatting the drive and installing fresh Windows 11). I plan to perform a clean install of the graphics driver using DDU (my card is an AMD RX 6600), though I’m concerned this might happen again with the next update. I discovered a website that explains how to prevent Windows from updating and interfering with the graphics driver. Do anyone know if this method works? And is it safe to try it?
I’m seeking advice on fixing the issue with my AMD graphics card in Windows 11. The problem started after an update and has become more frequent since switching to Windows 11 (after formatting the drive and installing a fresh OS). I’m considering a clean install of the graphics driver using DDU, but I want to make sure it’s safe.
I’m hoping this situation ends soon so I can use my PC without fearing random crashes. My current build has a CPU that will be replaced by a Ryzen 5700X in the near future, coinciding with getting a new PSU. The PC is still running on the old PSU.
