This is a fairly common occurrence in the NVIDIA GPUs in those models. Sometimes the root cause is failure of the chip. In that case, you would need to buy a replacement (new or refurbished) motherboard and replace it. On the other hand, it could simply be a weakening of the solder points holding the chip to the board. This is very similar to the infamous "Red ring of death" that plagued the X-Box console early on. Like the X-Box problem, solutions vary wildly and include:

  • Shipping the board somewhere for them to repair
  • Wrapping the running laptop in a blanket until it overheats, using a heat gun, or even sticking the board in your oven! (the goal being to re-melt the solder into a more solid connection).
  • Using pennies or some sort of copper "shim" to act as a better heat-transfer mechanism than the heat-pads it was designed with. (While this has worked for some people, it is unknown if this works because of better heat transfer, or just more pressure on the chip, thus allowing for a slightly better connection of the chip to the board).

 

I am not expressly recommending ANY of the above options, as they are all, in my opinion, bad ideas.

 

...Unfortunately, I can't think of any good ones either. Maybe somebody else here has other ideas for you.

 

I hate to be fatalistic but we ARE talking about a 7 year old computer here. Maybe it's time to replace it? I have to think the price of a new PC would be well below the cost/effort required to even attempt to fix this one.

Try the computer using an external monitor and see if the results are the same. If they are, it is a known issue with DV series as teh_charles mentioned for the video chip sets to fail. It is also possible a stick of ram is bad.

 

If you have 2 sticks of ram, try removing all but 1 stick, try 1 stick in both slots, if you have 2 sticks try each stick in each slot.


If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
