Can a faulty VGA cable be responsible for a system crash?

Hi,

I am investigating repeated system crash in a personal computer. The system is crashing unpredictably. I have received one blue screen so far. I want to know if a faulty VGA cable can be responsible for a system crash.

Hi,
I'm unaware of any dedicated vga cable for onboard graphic's other than the main 10-12 pin mother board cable or possibly 6-8 pin cpu cable :/
Which are you saying is a vga cable ?
Seeing that it is onboard graphic's which is apart of the cpu it would be the cpu cable but with onboard graphic's I would suspect a bad cpu if a new cable did not good.

But knowing now you're using onboard graphic's Yes a cable would cause crashes but so would a bad cpu.

@ThrashZone I am referring to the cable that comes out of the cabinet and goes to the monitor. The computer has an ASUS P5QPL-AM motherboard and LG W1943S monitor.

@ThrashZone A few months earlier the system started showing symptoms such as, the monitor would go to sleep with the LED blinking when I left after locking the screen. Resetting was the only solution. Another issue was the desktop would remain black and unresponsive for a long time after logging in. I was using the Blank screensaver with windows 10 theme for windows 7 then. I have disabled both and now using windows 7 aero theme. The device manager, dxdiag, sfc /scannow are not showing any problems. I have run a KIS Full Scan but it has not detected any threat.

In addition to system crash, the problem has at times escalated to extraordinary levels. Sometimes, after pressing the cabinet power button, the monitor remains in power saving mode with the LED blinking and does not reach even the motherboard splash screen. Once, booting stopped at the motherboard splash screen. The system is a dual boot system. Once, the grub screen's background became black, when I selected windows 7, I got "This file might be corrupt. The header checksum does not match the computed checksum", and when I selected ubuntu, I got "uncompression error system halted". I guess that was caused by too many resets. That is gone now. I am posting this reply from the same computer now.

The problem comes and goes according to its own volition. I have observed that the system has crashed when I tried to open the action center window to resolve the issue, "Solve a problem with Intel graphics driver", when I tried to open Intel GMA driver graphics properties, and when I tried to restore google chrome tabs immediately after logging into windows. These crashes are non-repeatable meaning, if I perform these actions now the system is not crashing.

Do you have another monitor you could test with? Sounds like you just might have a flaky monitor...

@redoak Have you read the entire thread including post #8? How can a flaky monitor cause so much problem?
