A Dell d630 is showing signs of failure:
- On startup, often nothing is seen on screen. it's about 50:50 if it starts up fine or does nothing
- Plugging in an external monitor when nothing appeared, we did see something on the 2nd monitor, and were able to login
- We have seen rare graphical glitches like odd patterns, entire screen starts flickering - these normally lock the PC up and require a restart
To me this smells like the GPU being bust, does that sound likely or something else? I thing a simple bad connection to the screen wouldn't cause lock-ups?
It's using the nVidia GPU option, not the integrated Intel version. Is it possible to fix/replace the GPU or will it be integrated onto the mainboard?
