today my screen became shaded light blue / aqua.

My motherboard is a Asustek M5A78L-M LE. My graphics card is a ATI Radeon 3000 graphics. My monitor is a HP 2009v.

Here's what I tried:

1) turned off  / on PC

2) plugged off and back on the video cable. It was and it is firmly plugged in and I didntdo anything to it whatsoever before it turned shaded blue.

3) disable and enabled graphics adapter

4) windows update

5) asked for an update of the graphics adapter from device manager. i already have the "best one"

6) asked for an update with driver booster . nothing.

7) uninstalled graphics adapter. it came back automatically

8) tried changing resolution

9) uninstalled graphics adapter and deleted drivers. it came back again automatically

10) tried to change color settings. nothing

11)i restarted my pc with a USB key with an UBUNTU installation in it (quite old, probably of 5 or 6 years ago). It has the same problem. This makes me thing it is not a problem of corrupted drivers.


When I start the PC there is a moment when it usually displays a white rectangle with some info, like, i guess, the current resolution. THAT rectangle is white. So I guess my screen is still capable of producing white.


What could I try now?


thank you so much

I think one of the primary colors of the graphics card has failed. I had a issue with a graphics card where the screen was a green tint. I switched to the integrated graphics and everything was fine. If this is the integrated graphics then swap in another monitor. If another monitor is not available then try resetting the monitor using the monitors on screen menu.

The day after.
I feel quite dumb, embarrassingly so.
Remember my check number 2? Usually, everyone tells you "check the cable" and I did it. But I completely forgot that a cable has TWO ENDS, not just one. I checked the end that enters in the PC but not the end that enters in the monitor. I dunno why but one of the two small screws that hold it in place wasn't properly screwed in and the cable was extremely loose. Once I screwed it in, everything was back to normal.


A lesson for everyone like me (hopefully not many): a cable has two ends, check them both!
