Ok so my system has had random BSOD crashes for about 8 months. I called tech support and they said to restore and see if that fixes it. Well it didn't but I finally got the codes on the blue screen. If someone could tell me what they are so I know if its something I can fix on my end or if I should place another call to tech support to have it repaired. It mostly happens while gaming but has happened while on the internet aw well.

did you reinstall windows so i can make sure that the problem isn't virus or driver issue
if you did ,usually BSOD happen because of RAM problem and some times because of HDD ,so if you have tow RAM sticks(mudles)try remove one of them and see if the problem occur

Yeah I restored last Jan at their request but the crash kept happening. I never got around to doing anything else because college Spring semester started up and I was suffering from a terminal case of couldn't be asked. I may restore again to confirm though.

Also it does have 2 RAM sticks but its a pre-built laptop so no mods done by me.

system restore cant always fix the problem ,and you didn't try to reinstall windows yet. and because of the warranty you don't want to remove RAM stick.
try to set bios to default it may help.
if its not software problem i am almost sure its RAM

memtest86 run it for a bit to test your ram. open hardware monitor to check your cpu temps.

Right now my CPU and GPU are running between 35-45c at basic internet browsing. I'll run memtest86 tonight and see what it says.

2hr Prime95 test says my max CPU temp is as follows. 87c, 91c, 86c, 90c. I'll try it with some gaming tomorrow and see what my GPU+CPU come back as.

Ok I did Prime95 again this time with laptop fans set to max and my laptop cooler in place. The test before was just under the laptops own cooling power. 84c, 86c, 83c, 87c.

your CPU temperatures are very high the easiest way to decrease it is to go to bios and disable tow core i7 cores or underclock your CPU so i can make sure if the issue because overheating or not

I think you guys maybe right about it being the temps. After Prime95 sent the CPUs to 97-98c I tested with FurMark to get what the GPU was doing when at load. It hit 100c in 4min 30 sec before I shut it down.

I don't think the laptops cooling is working properly. Well I mean obviously it isn't working properly. I guess warranty is the only thing I can do.

Edit- Just played Tribes Ascend on a target practice mode and hit a GPU temp of 101c.
