So I was playing when auddenly the monitor goes black. I restarted but to no avail. I did try moving the cable connected on the monitor from the gpu to the upper area near the processor and this puts images back on the monitor. Problem is it's weaker than the video card(even if it is weak). I have encountered this with older pcs but my uncle's solution was to replace the vid card. I dont really wana shell out some cash yet so i decided to consult you guys firts. So do i have to replace it already?

Add info: computer turns on, i can hear the start up sound.

Graphics: hd 5670

Proc: intel e6600

Im on mobile right now. Ill try to add some more info later
