every time i try and load a new third person project my computer freezes then says my graphics crashed is there any reason this may be happening?"
small note the version i have tested this on was 4.7.6 and 4.8.0 my graphics card is Intel(R) HD Graphics 5500 and i run a
Intel(R) Core™ i7-5500U CPU @ 2.40GHz (4 CPUs), ~2.4GHz
Integrated graphic cards are not recommended to use with the UE4 -> they could cause errors or the editor will run very slowly. 
oddly enough its only when i open a new project if i delete the first map and open the project again it runs fine is there anyway to fix the problem?
Yeah. A better computer. It clearly isnt able to run the engine if it cant even open the template maps.
everything else works fine (2D and all the other projects load without issues) only the third person one crashes on the template map so i don’t think ill get another computer i might just stay with lower scale projects
Is it also freezing when you set the scalability settings to low? But when you want to develop in 3d, you will need a better PC
if i have a 2D project everything runs fine (as long as i don’t use alt enter to put my game in full screen) i haven’t had any freezing issues or any of the sort in 2D as long as i stay out of full screen mode as far as scalability setting i have not yet tried changing it to see if it would stop the problem for 3D
problem was the shader set to 5 when it needed to be set to 4 before the engine loaded the project after some lucky attempts i was able to get the 3D projects to run even on epic settings with shader set to 4 and no more problems with it crashing
AMD integrated graphics actually work very well for small levels, you can expect downwards of 40 FPS though.
