Problems with my computer driver I think?

Alright so I'm playing this game called warframe, but after playing for a little bit the game crashes and says something like an error has occurred driver_irql_not less or equal(igdkmd64.sys). I updated the graphics card driver but after playing for a little while the game will eventually crash and display the same error. I'm not a computer guy and I don't have a strong knowledge on computers so if you know the answer to this problem then please explain to me step by step. I have a windows 8.1 64bit Lenovo, it has an integrated intel (R) 4600 HD graphics card it is an I5 quad-core processor. If anyone can help please explain it to me like I'm an idiot. I have no idea what to do and I really hope my $300 didn't go to waste. And please don't tell me Lenovo makes bad computers and I'm screwed, i've done research on the company and they are actually one of the elite producers, also this error only occurs whwn I'm playing games. And no it's not because I'm gaming on a laptop, I'm sure its the drivers but I would like some step by step tutorial on how to solve this problem.

The main problem is with the intel graphic driver go to intel.com and see if there's a patch for the driver, some people on this site had similar problems with running intel graphics while gaming, i can't give to much of a link because at the intel site a lot of changes has been made recently

I'm thinking the game might have somthing curropted in the graphics files in the game try re installing the game and if that doesn't work try calling lenovo and tell them what's going on.

hope this helps

It would seem like it is your drivers fault. If your driver is aldardy uoto date and still causing the same problem i suggest you downgrade to two or 3 versions below your current driver version. That should solve your problem.go to the driver manufacturers website and downlod from there. Hope this helps
