After 24 hours, Linux lags to near freeze
I have had Mandriva One 2008.1 Spring installed on my pc for about a week and a half now. The first several days Linux ran just fine. But, the last few days whenever I run my system for about 24 hours or so, at random my system will just start to lag severely to a near freeze, though it doesn't actually freeze. But, Linux has frozen too at random a few times. However, my system does start to lag so bad that I have no choice but to hit the restart button on the tower. From the start of the lag til my system becomes nearly frozen only takes a matter of seconds. Does anybody know what is causing this? I know it can't be my system because before I installed Linux on here, just a matter of weeks ago, I was running Windows 7 Beta on here and I had my system running for 20 days straight before I restarted and I didn't even have to restart then. So, I know it's got to be a problem with Linux. Just trying to figure out what it is. Anybody have an ideas?
