sry man, but you should get elementary knowledge about computer you are using, imho.
just make fresh install of windows, if you feel that something is not right.
do not blame game.
btw, DF can make more heat than fallout 3 imho.
And again, nothing from what I know has changed in resource usage in the past two weeks. In fact, if I open up the task manager, it tells me that it's using the exact same amount of resources as it always has been.
that proves nothing. f'ed up registry may not be visible in ..task manager.
not to say that you are not able to see real problems in task manager at all(as viruses, services, you won't see NOTHING serious if you are infected).
btw, never EVER use registry cleaners - it is begging for problems.
I got trojans
hint - antiviruses are NOT good idea to GET RID of VIRUSES.
strange?
antiviruses are good for DETERMINING what causes problem.
after that you may need to FIND SPECIFIC ways of getting rid of SPECIFIC virus, especially, if it is something serious.
hint 2 - main problem with windowses is their "system restore" option.
every threat stored there may be...restored.
good idea - turn off system restore service BEFORE attempting to HEAL system with external software.
it may sound strange, skip that if you do not know what to do..
This sounds like overheating to me.
..or his machine got bios reset and lost stable bus/cpu settings, or sth.
maybe loosen RAM, gfx card, whatever.
even stupid clogged fans, dying power supply, etc. etc..
it will run smooth as giant cave spider silk, but after a few minutes, it will begin to chug. BIG TIME.
turn off speedstep in bios then, check cpu temp there BEFORE doing that.

another idea - use hijackthis and post your log(..file
).
and finally - Vista is worst shit available, even win7 is better, not to mention good ol' xp(well, no dx10, tho).
sorry for ridiculous english, i am not native speaker(uh, writer).
