Hi guys. I have a laptop Asus K55VM. Today I was playing DOTA 2 and suddenly my laptop crash. I heared a specific sound from my headset for few seconds, the picture frozen and BSOD appear in the view. It was saying that I have problem with my page file and virtual memory and it started to count something. After 30 seconds the laptop restarts and my NVIDIA GT630m card disappeared. Device manager not detecting it, AIDA64 and other programs like that are not detecting it too. Can you help me with some ideas what I can do and can I fix this problem somehow? Do you think the video card failed and it will not work no more? Thank you very much! PS: Sorry for my english. It's not very good. System main info: Intel Core i7-3610QM 2.3Ghz, Intel 4000 HD, NVIDIA GT630m 2GB, HDD 750 GB. I think the other specifications are not interesting.
