Is there a problem with the video cable? Fans are running yet the screen remains off.
The system is reporting a "Check Video Cable" error. Reviewing the video may help identify the cause, as the LED blinking could indicate the problem.
What is that message on the screen? It appears to be an OSD (On Screen Display) from the monitor, not from BIOS or the system. If it prompts "Check video cable," there are a few options: the cable itself or its terminals may have poor contact. There might be a wrong port in the GPU or display if there are two or more ports, which should be adjustable via the display's OSD controls. For example, if the connection to the GPU is HDMI and the display is set to DVI, it wouldn't detect the HDMI cable.
I replaced the VGA cable with another one, but it still shows "Check video cable". Also, I attempted to get display output from the motherboard, but it didn't work. Neither my GPU nor the motherboard is displaying anything. I performed some basic troubleshooting: removed all RAM sticks and plugged in one RAM per slot until it worked—though that didn't succeed. I also checked the 4-pin CPU connector on the motherboard; everything seems fine, no burnout signs. This motherboard model is a Gigabyte H81M DS2v (rev 1.0).
I have an Intel Xeon E3 1271 v3 processor installed. It's been running for six months. I recently checked my CPU and GPU temperatures using the software hwmonitor. CPU temps were around 50-55, while GPU temps were 60-68.
I also have another CPU, an Intel Core i5 4460. I tried that one as well. The Xeon CPU doesn't have integrated graphics, so it shouldn't support display output from the motherboard. Using the i5 helped confirm this. It seems my motherboard might be faulty again.
What other troubleshooting steps can I consider? I'm running out of ideas.
I also attempted to get display output from the motherboard, but it didn't work. Since your CPU lacks an integrated graphics chip, linking a monitor to a motherboard port won't help either.
The Intel core i5 4460 includes built-in graphics. I previously used this processor and later switched to an Xeon model.
It's confirmed. What should I verify next? I reviewed the power cord and switched it on/off. The problem isn't related to the monitor or cable.
I'm unable to modify anything since the PC isn't starting, and the monitor only supports a single VGA connection.
