Has anyone been able to sort out the random system lockups on a Win2K system yet. I've read in previous posts that I'm not the only one experiencing this problem. It is a totally random lockup, as it can happen after 20 minutes, or sometimes up to 12 hours. Your PC just locks up, no error, no event logging, nothing. I thought it was my machine (I only use top notch components such as Genuine Intel Boards and Kingston memory), but after reading this forum, I've realised that it has something to do with the Sentech modem drivers, or settings in the registry (As I don't use the modem dialler, just a normal DUN entry). It must be something to do with their drivers and the USB port. I've even tried "Rodents" USB tweaks, but it still happens. It has nothing to do with their TCP IP patches, as it still happens with these installed, or removed.
