don't cringe....it's a pentium two, hp vectra running windows nt(this may be a stupid question

) but it will not open a majority of threads on the forum...my options and pms are not an issue, a few threads are okay and will open as long as they are not more than a page full(sometimes)and i can reply just fine to those or make new threads, but there are some it won't open, it locks up after just a few posts loaded and windows just keeps turning(does not give a not responding error in task manager), and then prevents me from going to other threads...i have to completely close out of the forum re entering until again i select one of the threads(it varies) and then repeat the process...any ideas?
