Hi there,
Specs: as per Qosmio X 300. SSD 110GB, pentium core 4 extreme, 4 Gb RAM, plenty free storage on SSD (29GB), NVidia drivers with primary being GE Force 9800 M GTS, Direct X10.  there is also a note down the bottom saying that if i have linked graphic cards (whihc i do i believe there are three), that i can expect better perfomrance with some software.
Ok I aplogise from the outset, i am a layman and not that techie. K.  So the issue that I upgraded recently (last week) from vista ultimate 64 bit to windows 7 64 bit. ultimate.  For the main, I am reasonably happy with the outcome in most areas - except gaming that is. I have increased speed and agility and the processor is now rated at 7.2. WEI. overall the laptop is rated at 5.8. however, getting back to teh reason for writing, I have nothing negative to say about windows 7 (as compared to its predecessor) apart from wishing to resolve my game crash issue. which usually occurs about 15 mins - 20 mins into a game and comes in the form of a shutdown ? BSOD from whence the laptop reboots when prompted at on/off and wants to know if to start normally or in various safe modes. I have noticed that the laptop does become very hot at the back (around the fans) prior to teh shutdown, and i am wondering if this is an overheating issue, and how to resolve if this is the case. the only other thing i have noticed that seems untoward is that i have apparently lost a wireless jump start driver from the upgrading process which i cannot find anywherre, and may be totally unrelated to this issue anyway.
All i want to do is play the games i could play on windows vista ultimate 64 bit. these include: Sims 3, sims 3 world adventures, sims 3 ambitions, highloft end stuff, and Bioshock. Oddly enough, i have played sid meyers civillisations revolutions IV (the latest one) with no crashes, and i havent tried ANNO 1404, but fear a similar fate may await this game as some of the others.
Addditional information:
everything is as i described it above, however the screen does not go blue but black,and the laptop shuts itself down,  laptop acts as if hibernating mode? (these are guesses) or some mechanism geared at preventing over heating - the back becomes very hot.  the machine can be rebooted from normal mode but comes up firstly with a screen suggesting that the laptop was incorrectly shutdown, and offers options as to safe mode, normal etc. i have been starting normally with no adverse effects.   This is scenario one.
scenario two ends up similarly at teh reboot stage, but gets there differently. i play the game and the screen freezes, unable to move touchpad curser, unalbe to use ctrl alt del to get up task manager. end up having to crash to reboot.
I am quite frustrated and very reluctant to mess around with things that i dont understand (dont want to make the problem worse!). I am happy to attemtpt to follow your good explicit advice.
the only other negative thing i am expereinceing is screen flicker on internet. I have changed my power mode from high performance to balanced to try to nullify the overheating issue but i now am noticing this screen flicker which is irriating and appears on keystroke, or cursor movement.
Please note well:  I am a layman, not a technician! Please explain in easy to (dummy) terms! Thanks!
kind regards
