is ignorance bliss?

i have a dilemma of sorts...
after much trial and error... and referencing from the internet...
i've finally managed to install EVERYTHING into one OS... which i am proud to say... is XP...
and not Vista...
oh..umm... everything meaning... all my hardware drivers...
so that now... currently.. EVERYTHING works on my XP...
including my video card...
working beautifully...
problem is... i haven't tried running anything that even slightly taxes it...
in vista, due to what i originally thought was a driver problem, whenever i play games or do anything that needs the vid card to work harder... the screen goes black every 5 minutes or so... before coming back to life... it lags too at times...

so... i thought that running XP would solve my problems... and so i thought... however, when i tried playing on XP... the thing crashed all together... hmm... and at that time... it appeared to be a driver problem again... cos' the pirated version of XP that i had couldn't seem to get the driver in fully also...

well... which brings me to now... now... everything's fine... from a software point of view...
but i haven't tried playing anything...

partly cos' if i do... and if things go wrong... then it'd mean i have no idea what's wrong... OR... that the problem is with the hardware...
hmm...
is ignorance bliss?

maybe i should just quit gaming...
