Computer is not going to start for a first time - 6930p

When i push start(power) button computer is turning on, window(screen) with bios is showed up after that Windos loading is interrupted. For turning on computer i have to do such things as:
1. (turn on computer)Push power button

2. wait, around half minute
3. turn off the computer with power button
4. turn it on again immediately after shutting down
After this, Windows is loading properly.
So what could be the reason of those issues?
Computer has non-genuine battery and besides of that everything working well

This behavior is usually a crack in one of the gold traces anywhere in any one of your circuits.  When the unit is cold the two sides near the crack are not making contact. When you turn the machine on and let it warm up, the gold expands with heat and the two sides press together forming a complete circuit again.  That will last until you shut the machine down and let it cool. This is very hard to find because it could be almost anywhere.

I'm not sure if is the reason of my problem. When computer is warm/hot (at least 30 minutes of playing a game) during the computer restart situation repeats but with such a difference: for turning off the computer and turning it again i have to hold the power button for a couple seconds.

The restart after 30 minutes of game play is probably a thermal problem or a solder problem under the video chip.  Download this program and see what the temperature of you notebook is:

You misunderstood me i've restar my computer on purpose i dont mean that it's getting overheating. I notice that if i leave CD in a drive computer is turning on without major problems (maybe a little bit too long). Is there any possibility for upgrade bios to "f20" or some newest levels of bios? If  i would like to ask for adding necessary files and some instructions- maybe it's something with bios...
