Hi there! I have been googling and browsing the web for solutions, then I found this forum! I have been searching through these forums as well, and it seems like this a good (sub-)forum to post my problem... Basically, since a month or 2 I have been having FPS lag spikes when playing games (like League of Legends, Tribes: Ascend, ...) and I haven't got a clue as to how to solve it. I downloaded software like Game Booster and Advanced SystemCare but neither of these got rid of my FPS lag spikes. I defragment my HDD every month or 2, scan for viruses every now and then, but alas... My laptop is a Toshiba Qosmio X300. I bought it 2 years and 3 months ago. These are the specs: Intel Core 2 Duo CPU P8700 @ 2.53GHz (2 CPUs) 4060MB RAM Windows Vista Home Premium (6.0, build 6002) NVIDIA GeForce 9800M GTS If you need more information, please do let me know. Many thanks in advance!
