Hi, I am a big fan of Counter Strike: source when I am not lagging everywhere or when I am not kick by console because my ping is to high. To start off here is my system info: CPU Intel Celeron 3.33 Ghz Motherboard ASUS P5GC - MX/1333 Memory 2.00 GB of RAM Videocard NVIDIA GEFORCE 8500 GT 512 MB Soundcard/Speakers on board sound card with Altec Lansing sound system Hard Disk 232 GB HARD DRIVE Operating System MICROSOFT WINDOWS XP PRO 32 BIT Internet 3 mbps (wireless) Now I always get a high ping of +140 and some time +200 around 3:00 pm and at 11:00 pm it sometimes drops to 80 or 100. In the morning I can get from 60 to 100 ping at 9:00am to 2:00 pm. The thing is that when my ping is at 110 or 85, on my computer screen it looks like I don't lag but it turns out I do. I have tried all sorts of thing, disk defrag (many times), clean sweeps (many times), all kinds of programs ( CCleaner, Auslogics Speed Booster, full system scans with my Norton Anti-Virus to see if there is a virus some where, and RegCure). But nothing has seemed to of worked. I had another computer before this but my sister now has it, but I seems like I don't get as much complaints about lag with that one then this one now but I don't know how since my new computer has 256 mb more graphics memory. I have also thought about the Killer K1 ethernet card but I have read mixed reviews. If someone can help it would be great.
