text: i have a dell latitude cpx, after about 1 hour of using it, the display freezees. could iit be haardware ??   this could be hardware, but it sounds more like viruses and spyware are degrading the system.  if it was hardware you wouldn't be using it for an hour.  i recommend you use system restore, or format your hard drive and reinstall windows.  this would be the cheapest way to find out, unless you have important data.
