Hi, i am recently facing hdd hanging up while using heavy memory usages programs. But after much thorough tests, i have not been able to come to any conclusions. I had a friend who commented to me that my ram may be the culprit. My computer is now on the verge of always hanging. Thus i would like to enquire is there any diagnostics tool to access whether the ram is functioning in order? May i know how do i engage in repairing it?

It is suggested you test 1 stick at a time... which requires you physically remove the rest. You must stop it manually-- it takes a while-- I'd run it for 20 min on each stick-- small app-- fits on a floppy if you have one.
