hello everyone.i have very little knowledge about laptop hardware and this is why i am posting here. i have a compaq presario v6000 and it has been running fine for the past couple of years.a while back it started making noises and started heating up,but it never self booted or shutdown by itself.i had planned to get it serviced and clean its fan etc but it got delayed..2 days back,when i tried turning it on, it just wouldn't.i mean i switch on the power,i see the volume and power LEDs turned on but the screen wont appear. i believe its graphics card has burned up or something. i have dropped it off the repair shop and all that they are doing is just scaring me saying that the graphics card can't be replaced as it is;the entire motherboard has to be changed.and even if the card could be changed,it wouldn't give any guarantee of not burning up again so guyz here is my question: can the graphics card of a Compaq Presario V6000 notebook be replaced?i donot know which model it is but i guess its the default card that comes with every notebook of the said model. i would really appreciate a quick response as i need an urgent verdict.i can not afford an entire new motherboard at this time but i need to work on the laptop..
