Monitor problem! Can't figure out the cause...

Hi guys! Faced really strange problem. Got a PC with Nvidia GeForce 6150 graphics card with no overclocking. Sometimes the monitor loses signal and does not work. Sometimes it works just fine.

I've tried different VGA cable and different monitor, situation didn't change.

I've got 4 different connectors. 1 VGA and DVI on Nvidia + 1 VGA and DVI built in into motherboard. Sometimes, when the Nvidia doesn't work, I connect to built-in card and monitor starts working. Next time when it's out, I connect back to Nvidia. There have been situations when only one of the four connectors is working. This means that on one graphics card there may be only one connector which is functioning.

I don't get this. Problem isn't in the display nor the cable. It also doesn't seem to be in the graphics card as the built-in connectors aren't fully functional neither.

Please help me out guys!

first of all make sure all the drivers are up to date, and get back to us

Which drivers are you talking about? The PC was working just fine before. I don't see why the drivers might be causing the problem.

BTW, when I click "check for updates" in the device manager, it states that drivers are up to date.

your Nvidia drivers. last update was about 4 weeks ago.

just because it was fine a while ago, another windows update or such could cause an issue with the current drivers. Last AMD drivers caused my rig to Blue screen randomly.

if its a hardware issue theres nothing anyone on the forum can do, other than say "yep its fudged"

If it's the driver, why aren't the motherboard built-in connections working neither?

Installing the Nvidia driver ATM from Nvidia's website.

Same problem still present after the driver install... What should I try next?
