.1. the problem occurred with another monitor too, I replaced that monitor but the problem is still persisting, the other monitor had problems, it was dying from 10 years of use, black bars at the bottom, the current monitor is used also and have vertical black barsIt sounds like you are experiencing a problem where your monitor loses signal while your PC continues to run. Given the information and screenshots you've provided, let's troubleshoot the issue step by step.
Possible Causes and Solutions
1. Check Connections and Cables
- Ensure that all cables are securely plugged in. A loose HDMI/DisplayPort cable can cause signal loss.
- Try using a different cable to rule out a faulty one.
- If your monitor has multiple input ports, try switching to another port.
2. Graphics Driver Issues
- Outdated or corrupt drivers can cause display issues. Update your GPU drivers to the latest version:
1. Go to the GPU manufacturer's website (NVIDIA/AMD/Intel).
2. Download and install the latest drivers for your GPU.
3. Monitor Settings
- Check the monitor's settings to see if there is any power-saving mode that might be causing it to go to standby.
- Reset the monitor settings to factory defaults.
4. Power Settings
- Incorrect power settings in Windows might cause the monitor to turn off. Adjust settings as follows:
1. Go toControl Panel > Hardware and Sound > Power Options
.
2. Click onChange plan settings
on the selected power plan.
3. SetTurn off the display
andPut the computer to sleep
toNever
.
4. Click onChange advanced power settings
and ensure 'PCI Express > Link State Power Management' is set toOff
.
5. Test with Another Monitor
- If possible, connect another monitor to see if the issue is with the original monitor or the PC.
6. Hardware Issues
- Overheating or failing graphics cards can cause display signal loss. Use software like HWMonitor to check your GPU temperatures.
- If temperatures are too high, clean dust from your PC and ensure proper airflow/cooling.
7. Unified Remote and Chrome Remote Desktop
- Ensure that these applications are not interfering with the display settings. Try disabling them and see if the issue persists.
8. BIOS Updates and Settings
- An outdated BIOS can sometimes cause hardware compatibility issues. Check your motherboard manufacturer's website for any BIOS updates.
- In the BIOS settings, ensure onboard graphics (if present) are disabled when using a discrete GPU.
Given the provided images, it seems you are able to access system settings through a secondary interface like Unified Remote or Chrome Remote Desktop even when the monitor goes black. This suggests the system remains operational, and the issue is most likely with the graphics card, cables, or the monitor itself.
Please provide updates on the outcome of these steps or if you need further assistance.
Heres the occt psu testGiven the additional information and the stress test results you've provided, it appears that the issue might not be related to your monitor, cables, or power settings. Instead, the random nature of the signal loss points towards a potential issue with your GPU or PSU. Here are some further steps you can take to narrow down the cause:
1. Check GPU Temperatures and Performance:
- Download and install FurMark.
- From the stress test results, it seems your GPU temperatures are within a reasonable range (46°C to a maximum of 84°C). However, ensure these are not spiking dangerously high during intense tasks as this can cause instability.
- Use software like FurMark to stress test your GPU further, monitoring for any shutdowns or signal losses.
- Run FurMark and start a stress test.
- Monitor the GPU's temperature and performance in FurMark. Look out for any sudden drops in GPU activity which could indicate instability.
2. Test the PSU:
1. +12V should be between 11.4V and 12.6V
- A failing power supply can sometimes provide inconsistent power to the components, leading to issues like random signal loss.
- Use a multimeter to check the voltage outputs from the PSU. Ensure they match the specifications (±5% of the nominal value):
2. +5V should be between 4.75V and 5.25V
3. +3.3V should be between 3.14V and 3.47V
- You can also use software tools like HWMonitor to check the voltages under load, though this is less accurate than a multimeter.
3. CMOS/BIOS Settings:
- Sometimes, resetting the CMOS/BIOS can resolve hardware instability issues:
1. Turn off your PC and unplug it.
2. Open the case and locate the CMOS battery.
3. Remove the battery for a few minutes, then reinsert it.
4. Alternatively, you can use the CMOS reset jumper if your motherboard has one.
- Once done, enter BIOS and load the default settings.
4. Swap Components:
- If possible, try using a different GPU or PSU in your system. If the problem goes away, you've identified the faulty component.
Steps for Further Stress Testing:
A. GPU Testing with FurMark:
1. Download and install FurMark from the official website.
2. Run FurMark and select the resolution and options suitable for your setup.
3. Start the stress test and closely monitor the GPU temperatures and performance.
B. PSU Testing with OCCT:
1. Download and install OCCT, a free stability checking tool.
2. Run OCCT and select the PSU test option.
3. Start the test and monitor the voltages, looking for any instability or significant drops that could indicate a failing power supply.
The random nature of your issue makes it tricky, but focusing on these stress tests and voltage monitoring should help identify if your GPU or PSU is at fault.
