Hello TechSpot Community! [[Minidumps are zipped in the first answer to this threat.]] I am experiencing really strange behaviour of my relatively new Packard Bell EasyNote TS11 Notebook, including a really strangely bad performance and the BSOD mentioned in thread title. System Specifications are the following: System: Packard Bell EasyNote TS11 CPU: Intel Core i7-2630QM GPU: nVidia GeForce GT 540M, 2GB VRAM RAM: 6GB DDR3 OS: Windows 7 Home Premium Since I am talking about a Notebook, I do not know the mainboard and PSU specifications. So, what ist the problem? First of all, the System seems to work much slower than expected. Even in older Games like for example Company of Heroes (which was no problem for my much older HP Pavillion Notebook) I have to turn down graphic options in order to get adequate FPS. I also recognized, that the system was overheating especially in the hot months of last summer. I believe this caused another performance decrease, but I am not quite sure about that. What I am nearly sure about is, that there have been some overheat-shutdowns. So I bought an external notebook cooler, which stoped the system from overheating that much but didn't solve the performance problem. Using the external cooler it was at least possible to play games at low graphics, but also with bad performance. For Example, when I played World of Tanks, which I believe not to be that graphic-intensive, from time to time FPS drops from about 50 to 10-15 without any understandable reason and even at lowest graphics. So I wasn't really satsified, but ignored the problem for a while. But now I experienced a new Problem, which is that I am totally unable to play Warhammer Online, because I get the BSOD mentioned in threat titel, every time after a few minutes. Since I am using the cooler on maximum and experience the problem even when the external temperature of the system could be descriebed as "slightly warm" I do not think it is an temperature problem. But that could be wrong. So what did I already do? First of all, I have read your "before posting minidumps"-manual, but since the system is a notebook, I was unable to do many of the steps. Since the BSODs mentioned nvlddmkm as the causing driver, I tried new graphic drivers from the newest one to the one brought with the notebook itself. (Please notice, that right now I have installed the old one but I did try the newest one as well as some of them in between.) But nothing helped. I also followed some instructions to deal with the nlvddmkm-problem like uninstalling graphic driver, deleting the nlvddmkm in secure mode and reinstalling new driver after that. But again, nothing helped. The only thing I seem to have achieved is that the BCCode of the last BSOD was another one. (By the way: Please notice, that the BSODs all said that nvlddmkm was the problem, and NOTdxgkrnl like the minidumps say) So I do not know, what to do further. Can you please help me? Kind regards, PapaDragonov Ah, one additional thing: I also tried the Windiws 7 Memory check and it found no errors.
