Hi everyone. My name is Rick. I just found this forum and I noticed there are a lot of nice people willing to help others. Kudos for that. To start talking about my problem, there are two things that you should know about me: 1) I know close to nothing about PCs and Hardware etc. 2) If you are willing to help me, please avoid acronyms as I've no idea what they mean. My issue is the following: Every once in a while, while playing, my graphic card stops working for a couple of seconds. When this happens, my screen turns black and when it returns to normality, I have to close and open again the game because it turns white. On my pc, this is the message I get when this happens: "The driver video NVIDIA Kernel Mode Driver, Version 311.06, has stopped answering and it has been correctly restored". Few notes: h) I've updated the drivers regurarly to the latest version avaible everytime and this STILL happens at the version 320.49 i) My graphic card is a GeForce GTS 450 on this computer l) It does not happen in every games m) It DOES happen (althou less frequently) even when not playing and just browsing google chrome n) I've already trying searching with google. Haven't had any luck or/and if there is something they tried, I couldn't do it because it wasn't explained how to do it. o) Sometimes it does not turn back to the normality and I have just to reset my pc. Now, I've no idea what these infos are or if they are helpful but I'll list them here: ACPI x64 based PC Intel(R) Pentium(R) CPU G860 @3.00GHZ RAM 4.00 GB 64-bit If you need to know more, please tell me where to get the info you need and I'll list here. If I need a tool to get you more infos, I'll download it and copy-paste everything you need. I'm really desperate, help me please. EDIT: I've download also GPU-Z so if you need something from that, let me know.
