I reformated for the first time in 3 years of having the computer the other day, and now after reinstalling programs such as Steam, and installing Counterstrike, I find that I literally can't play the games because of the extend of the lag I'm getting. I ping fine, with a latency of only 30 or 40 at some servers, but I constantly spike up to 300+, causing me to freeze for a good second or two and ending up on the other side of the room after the spike. I dont know what could be causing this - maybe someone here has an idea (and step-by-step instructions on how to do them )? Note that I'm on a wireless network, using a Linksys router and a netGear receiver. However, I don't think that is the problem because I've had an identical setup before the reformat, and I wasn't lagging at all. So any ideas would be awesome. Thanks a lot guys!
