Fixed graphic mode causes windows freezing dv7

Question

Hello guys,
I have a question about my hp dv7-6b21sm which has i7 2670qm, 8gb of ddr3, 1tb of hdd and a hd6770m graphic card. Now to the problem.
A little ago I've figured that battlefield 3 will not run in fullscreen unless I turn on "Fixed" graphic mode in bios. So that's what I did, switched from dynamic to fixed. And now the problem steps in. Everytime I choose the "fixed" mode, the PC boots into windows and then works for, let's say about 2-3min and then freezes and a reboot is in order. Dynamic mode doesn't do that. I have found no bios upgrades, mine is a version F.02, so I've tried to flash it to F.1b and it is not working. Just says that this driver is not for my dv7.
The next problem I've came across aswell is that if I run the game call of duty 2, the game automatically chooses the Intel hd 3000 although I've set the switchable graphics to High Performance. What the F? Still runs pretty smooth but I can't keep it with constant 250 fps ingame (don't ask why, a matter of being used to playing at that framerate).
The third problem looks like it is some sort of a "Standard" for HP. Overheating. My god. I'm playing skyrim on lowest settings and my gpu idles at about 50°C when under load, it jumps up to about 80°C. Is that like normal for HP notebooks? I remember playing it on my brothers ASUS and his max temps were about 60°C in a high mode, with same specs as my HP only graphics were Nvidia gt555m.
Oh and just remember the 4th problem. Youtube HD videos. Why is it that if I watch a HD video ripped from blu-ray, the picture is clean and sharp and colorful. Even Vimeo works like a charm on this machine for watching HD videos. Now when I go to youtube, play a video in 720p or 1080p or even Original quality, and put it to fullscreen, everything becomes square-like and choppy and graphics look like they are 240p stretched to full screen. I mean seriously HP...Is it that hard to make something with a little more quality to it? I've payed like 1000eur for this machine. For that money I would expect that it'd be working like charm.
Thank you for your replys guys,

Overheating is commonly reported in HP notebooks during intensive tasks like gaming. 80 degrees seems suspiciously high for gpu temps, are your sure you didnt mix this with your CPU temp. I have similar specs except with 1gb of vga memory and can normally play Skyrim at high settings at 1366x768 res, temperatures for my cpu can range from 60s to 70s but my gpu rarely goes past 70 degrees. If you set HP coolsense to 'coolest mode' this should solve your problem. As for your graphics problem, have you tried updating to latest amd drivers? 8.882.2.3xxx should be latest
