Graphics Card Spinning But No GIving No Signal On Monitor

[saifeealii]

Hello Guys,
Today when i turned on my desktop and i gets no signal on monitor.. this thing happened sometimes before.. and whenever this happened i just turned off the PC for a while and turned it on after some time and everything seems well. But when today this thing happened i did the same but the problem keeps occurring so i opened the computer then i unplugged the graphics card and then re plugged it but the problem is still occurring.. after this i turned on the PC and observed more sharply and i realized that the graphic card's fan is spinning.. and i unplugged the blue wire from graphics card and i plugged the wire in onboard graphics and my monitor got the signal.. i am a little bit sure that this is happening because of my PSU because the PSU is only 250 Watts.. but i am confused that before this problem automatically solved not this time

My Specs:-
Intel Pentium G645 2.9GHz
6GB DDR-III Ram
250GB HDD
Quadro 600 (graphic card)

First change your psu.
I suggest you to buy corsair vs 450.

2. Check your RAM.
Change your ram or clean your ram slot.
3. Run your system on inveter or UPS only turn mains off

That's happens with me some times.
