ok make sure before you load drivers that any unecessary programs are closed and not running . you can do this by going to task manager or disabling it in toolbar. Also how much
ram or hardrive space do you have .? could be not enough
ram , possibly defective
ram modules . Defective memory can cause errors. Or if this isn't the case see how much harddrive space yo have . To do this go to my computer , right click on C , D, or whatever drive that you use . If alot of space is used up try to get rid of things you don't need or run scandisk , or disk cleanup. If none of the above works , your computer isn't fast enough or is too old. Or could be hard drive related.
