make sure ram modules and cmos batteries have dust free secure seatings and cmos battery has charge some motherboards cmos batteries are soldered in
you might not have enough computer ram
not having enough computer ram will run your computer over its limits putting to much strain on the CPU central processing unit and can cause memory dumps
you might have to many programs trying to or accessing the internet at the same time scroll to bottom toolbar (bottom of screen) right click select task manager applications you will see whats running if you see anything you dont need running select end now and you might uninstall that specific program if you or computer does not require it to run and some unnecessary programs that could be jamming up your computer also under processes see what is ticking over in the background again if you see something you dont need to be and users you will see who is using your computer you might need to add more computer ram if you're not sure if a module is right for your system use the Crucial Memory Advisor tool for a list of guaranteed compatible modules. first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system you should always ask for a guarantee on the compatibility of the ram before making any purchase
