Silkroad screen

Well i've got a very good PC (intel duo core 3 Ghz 4GB ram 512 mb video card (nvidia 9600 GT top) ) though when i start playing i get black screens for like 1-2 secs.I was wondering how to fix this?The thing is i start playing killing mobs and the screen turns dark all the time and i'm getting so pissed!How do i fix this?

buy a shter pc xD but to topic... what opsystem do you use?

I use windows Xp proffesional with service pack 3.And my PC is quite new!(talking about isro).ON my old PC (700MHz amd duron 512mb ram 128 mn video) i did not have that problem.

can i be honest? dont have a clue...
but still, try to refresh your drivers (lame advice but cant think of anything)

i had a similar problem a few weeks ago, the sro spiked every 5secs, the prob at me was that i had an old hdd in as second. so if you have your old hdd also in then just take it out lets see if the problem persists
