Hello

 

My desktop PC was working fine on Monday night but when I switched it on this morning the screen goes fuzzy whilst it starts up (looks a bit like a magic eye picture). After that the screen goes blank and the "no connection" message flashes up. Does anybody have any ideas as to what's wrong? I've tried a different VGA lead and the monitor seems OK because the colour and contrast menu comes up OK.

 

I've attached some pictures.

 

Thank you

Hello The_famous_Devlin, 
 
My first guess would be a poor connection somewhere, and since you've tried a different VGA cable the problem might be in the graphics card or it's PCI slot. If it is an external one, and if your motherboard supports an integrated video - switch to the other VGA port, set it up in BIOS as a primary video device and try again. If not - go ahead and try another GPU, and it is also worth updating to the latest drivers (if you're able to work with it at all). Safe Mode is also worth trying, but if you have a hardware problem it probably won't make any difference. I will be waiting for your response and help with further advice, if needed. Best regards, Citizen_WD

Thank you for that.

 

I've just had a proper look inside my PC. I have two 256MB nVidia GeForce 7300 CS nVidia SLIT Configuration graphics cards. One one of them (not the one with the monitor plugged into it) the fan isn't spinning. I'm assuming it should be! I've tried just using the one that seems to be working but nothing happens at all. i assume it can only work if both work.

 

Thanks
