My computer shutdown automatically.
Later I tried to switch on the machine again but it (CPU) gave 1 long beep and then 3 beeps.


On monitor, it shows that it's trying to find signals (showing HDMI - Digital - Analog) and then monitor goes to standby.


Open the case and found that display card's (8800GT) is stopped and its not working at all.
Remove card and clean it. Still fan was not moving. Clean fan properly and used WD40 and fan started working now.


Placed card back and cabled. But still machine is coming up but there is no display. CPU is still giving 1 long beep & 3 beeps and monitor still showing HDMI - Digital - Analog.


I wonder if GPU is dead!!! But how come fan is working. Do i need to buy new GPU now. Pls help.

Hi; there may be the possibility that the graphics port is busted. If you have a spare GPU you could try that and see if it displays. If it does then it's the GPU, if it doesn't them it may be the port.


If your GPU is discovered to be the culprit then you could try baking the card in a short term attempt to save it; baking supposedly reconnects the silicon connections the card has that wears over time, if you bake it then the video connections would work again... If it doesn't work then a new GPU card will be in order.


Hope we can help you get through this situation.
