Not sure if this is the appropriate section to post this in, if it needs to be moved that's fine. My problem is we have several HP tablet PCs all but one of them out of 5 will randomly freeze while browsing drives. In task manager explorer.exe is at 50 percent and the pc locks up. Is there any software I can use to determine where the conflict is? I have done a reformat of one of them and updated drivers, the problem is still there but not as bad. I also replaced the hard drive before the format. All scans with KAV, SAS and Dr Web come up clean. I almost forgot, I am running XP. Any ideas would be appreciated.
