A few months ago my Pc had an issue causing my graphics card to completely fry, so after it eventually got fixed it worked for a while but then started to get many crashes and I remember when my graphics card fried it replaced the name of my graphics card in the device manager from amd radeon 6670 hd (at least I think) to a AMD Radeon R7 200 series however once repairing it I went to see what graphics card I had replaced by my friend and by my surprise it was still the AMD Radeon R7 200 series from before, could this be the cause of crashes as there is graphics card listed in the device manager which isn't actually there and if there is a solution please inform me, some of the crashes have mention messed up configuration but I wasn't fast enough to get the crash name and/or save it somewhere as at the beginning it didn't seem to much of a problem as it would start back up soon after and happen later.
