I have this issue where I get a lag problem when I am doing more than one thing at a time, for example, if I am on Facebook on one monitor and trying to watch a movie or an avi at the same time on the other monitor I get bad lag, like a very quick pause, some times even a full freeze for up to a minute. I am using Windows 7 64 bit but went back to Vista 64 bit the other to test and had the same problem there. The browser is Firefox (tried in safe mode which made a bit of difference but didn't fix it) Any help would be appreciated Intel Core 2 Duo E6850 CPU 2 x 2 GB Kits Kingston Hyper memory 1066MHz MSI P35 Platinum Combo Creative X-Fi Titanium Pro Soundcard Geforce GTX 285 Video card Thermaltake 1000W Toughpower PSU Compro T750 HDTV Dual Tuner PCI Card Thermaltake Bigwater 745 water cooling 2 x Acer 233H 23" Monitors Logitech G5 2007 Mouse Logitech G5 rev2 Keyboard
