No signal problem confusing panic (halp)

[CavebobSpongeman]

So I've had a recurring problem lately and I need help just finding out what's going on, I'm in the dark here (it's my first build so zero xp)

 

Basically, my pc sometimes won't display a signal on my monitor (it's really inconsistent). The first time I did it, I panicked and searched Google for a solution and what I got them was that someone just happened to unplug something from a usb port and it seemed to work, doesn't seem like an actual thing but I did and and hey-presto it worked.

 

Happened again another time, this time I didn't have anything plugged in apart from the basics (mouse, keyboard), so I did the good old turn off/turn on trick and after a couple of goes voilà, it worked.

 

Now, it happened again and no amount of off/on fuckery managed to work, I searched Google again and saw that some people said it could be an issue with the GPU, to unplug it, remove it, clean it, etc. and put it back in. I opted to be lazy and leave the drastic 'unplug everything' plan for my last resort. I got to the point where I had to unplug the PSU from the graphics card and plus that back it. This worked.

 

And after all this, I still don't get what the problem is, why it's so inconsistent or when/if it'll happen again. So, for my own peace of mind/sanity, could anyone hazard a guess to what the fuck is going on?

Perhaps the backlight of the monitor doesn´t come on.  Try another monitor and see if it has similar symptoms.

The monitor turns on and off like normal, just displays the 'no signal' notification sometimes.

Then try a different cable for the monitor.  You need to try one thing after another to find out what may be wrong.

 

That the graphics card is from Gigajunk might not exactly help.  They are  one of the worst manufacturers.

If you have another pc, I'd suggest trying the parts one by one on the working side pc to see what causes the problem exactly.
