Help about HP G62 for video card

Hi i have a Hp G62 notebook since 2010 with Win7 installed but
lately the screen shows sometimes some lines and sometimes
switchs off the screen even the system is working...
Sometimes appears the blue screen with some errors about video card.
Now i have scanned for possibly malwares but now i think that is
cleaned.
What do you think?
Is hardware or software issue?
Need i format the system to exclude if is a software/driver issue?
If is a hardware issue how can i solve it?
Can you help me?

Possibly a bad cooling fan or dust accumulation. I'd check that first.

Had a similar problem with another HP model and after determining it
wasn't a heat or dust problem I ran cable from the notebook to a
monitor. Still no image. Took it to a friend who works on computers.
Video card was shot.
Hope you have better luck.

I haven't seen the earlier part of this thread, but does sound as if
it's the internal video hardware - specifically that driving the actual
display - that's at fault.

Did you use the external monitor at the same resolution as the one that
isn't working?

(If it's a laptop, have you eliminated the possibility the internal
display has just been turned off? _Some_ of them don't come back, though
most these days do detect the absence of an external monitor at boot and
reset themselves accordingly.)

If you look at the non-working display at odd angles, with bright
lights, do you see _anything_? If so, could just be the backlight.
