Dell N5010 8 Beeps

The display on my laptop goes funny and then goes off completely. The only way to shut the laptop down is to hold down the power button.
When I turn the laptop back on, I get the 8 beeps. Googling this problem it seems to be a GPU or screen problem.
Others that have had this problem have said that by connecting it to a tv via hdmi works, however i get the same problem which leads me to think mine is a GPU problem rather than a screen problem.
I have stripped the laptop down, cleaned the fan and re-done the heatsinks. Laptop worked for about an hour and then the problem re-appeared.
A YouTube video suggests heating the GPU up to about 260C and then letting it cool and then heatsink. I'm a bit loathed to do this.
My bios and video drivers are all up to date.
Anybody got any suggestions?
Cheers.

This method is to re-flow the solder joints on the GPU to (hopefully) restore the physical connection to the pcb tracks underneath it. The chip uses a BGA (Ball gate array) for this. It can be risky, as there's no guarantee it'll work and you may fry the GPU trying anyway. It does sound like it may well be the issue you've got though...
heat-gun anyone??
as a test, if you apply gentle pressure on the gpu's heatsink (pushing the gpu towards the motherboard) can you get it to boot and run properly? If so, then the gpu itself is ok and it is a case of re-flowing the solder as above..........Gettin' There, Wherever There is......
I have a dodgy "i" key, so ignore spelling errors due to "i" issues, ...I blame Apple0 -
Well it looks like I have truly f@£&ed it. Tried to re-flow it, but now I am getting 3 bleeps which Google suggests is a motherboard problem. Doh!0

those sort of repairs are very hit'n'miss.... nothing ventured, nothing gained. It was borked anyway before you started, so have only lost an hour or so of your time..........Gettin' There, Wherever There is......

Just an update:
Managed to get a new motherboard from ebay for about £120, installed it myself.
Initially laptop was very slow, so I booted up in safe-mode, took all my pictures and important files off hard drive and then re-installed windows.
That was 3 weeks ago and laptop has been working a treat since then.
Thanks for your help/0
