It sounds like what he is saying is this. He took apart the computer, reseated the CPU and GPU with new heatsink paste, cleaned the fan and what not, and then turned it back on. 5 minutes later it started acting up again. So he looked at the fan under the keyboard and it was stopped again. So he replaced that fan maybe, and now it works fine.
That is pretty much how I interpreted it. It could very well be a heatsink issue. I still have mine. I have not had any motivation to anything with it, except get a 2.5" hard drive enclosure this week to take out the drives and use them as storage. Maybe this will be something work looking into. If the board is not toasted from being over heated, then maybe it would actually have a chance. ??

Thanks JW. Might be the heat sink issue - i think that was already established a while back when someone here mentioned that using the hair dryer can speed up the booting. I have tried twice and both worked, so it's got to be related.

So I rarely post on forums...to be honest I never do, but I had to create an account and tell you how I managed to fix this annoying problem.
So I have a HP G56 model 220CA and yesterday morning I woke up and my screen was completely black. It was beeping 1 light every 5 seconds, for about 15 minutes. Anyway I searched and searched through forums, and the general consensus was that my CPU had failed, and that I would have to send it in to HP. Anyway, I called HP support, got on the phone with one of there tech agents, he asked me my name and model number, and than asked me what was happening. I explained, and with no troubleshoot what soever he told me that my motherboard was friend and that it is in my best interest to have it shipped and pay $329.00 to replace my motherboard.
I was a little confused on how he was able to diagnose so quickly that my mobo was fried, but I went along with it anyway. I told him that most likely I would not be sending it into him, and he was confused and didn't understand why. I told him that I had searched for about 3 hours, and found about 30 people with the same problem I am having, and that this is a common problem with HP's and that I am not going to throw money at **bleep**, and exspect it to smell like roses. Anyway in the end I told him I am buying a lenovo and to go to hell....
Well, after that I was pretty much pissed right the hell off, my warranty ended 1 month ago, and I wasn't putting any more money into this laptop. So then I rememberd something I had done along time ago with my Xbox and it actually worked when it was red ringing... So I took my laptop, wrapped it tight into one of my sweaters, and let it run for about 20-30 minutes... I came back 30 minutes later, it was right hot, but the computer had actually powered itself off.... well I then tryed to power it back on, and voila ... it works... hope this may help some of you. Good luck!
Oh also just to clarify the light beeping was in fact the caps lock.
and after I got back up and booting properly, I flashed the new bios and am now running smoothly for the past 5-6 hours.

You mean you closed the lid and wrapped the laptop tight with sweaters while the machine is on? and the machine didn't get fried? I'm even afraid of unplugging the cooling fans while the machine is on as i worried it might melt to pieces. lol

Haha, yeah I am with Niniss on this one. LOL
I think what happened is that you essentially reflowed the solder on the board, all within the laptop case. You got it hot enought that the solder actually melted whatever was causing the short, and it worked. Not bad if it actually works for a while. I would be expecting the issue will come up again after a while. It is a manufacuring defect that is unfortunately ignored as such. If it were acknowledged that the product was made with inferior components, then they would have a huge problem with trying to cover fixing them, so they wont.
