Winsock Provider Catalogue problem

I get this problem where the pages don't load right or don't even load at all in firefox and internet explorer. It happens when I run my computer about 9 hours long then it starts to happen then I have to "restart my computer" or use the "WinsockxpFix" to fix it, but the problem is still there after, 9 or more hours the same thing happens. Alright I know it is not malware causing it because I did numerous scans also internet explorer 8 said the problem was something wrong with the, "Winsock Provider Catalogue problem" and to restart you're computer. Which I already did but didn't help it still persists. Anyone know how to fix this? I'm trying to run my computer 24/7 but this happens.
