Hello! Today my Dell Inspiron 1420 laptop started giving me problems. While playing Eve Online and even while simply working in Microsoft Word once, I start to get graphical artifacts and my computer locks up, forcing me to hard reboot. The glitches are neon colors and sometimes only last a few seconds before disappearing, leaving me on a locked screen that's otherwise normal. Audio glitches also sometimes accompany the problem, skipping and repeating the same noise over and over. Upon hard reboot Windows looks fine, but when I try to do anything, the problem happens again. I thought it might have been dust in my heatsink so I opened up, removed the heatsink, and cleaned around the CPU and heatsink. Nothing, the problem persists. I then cleaned off the thermal paste that Dell put on there between heatsink and CPU (an abysmal job) and reapplied a fresh layer of ArcticSilver to no avail, the problem persists. Only two times out of a total of 10 today have I got BSOD. The first time it was a crash from Eve Online and the screen read something like "Hardware Malfunction, contact manufacturer." No error codes. The second BSOD was more in depth and it gave me the following codes: "Stop: 0x00000116 (0x869c7008, 0x8E4F1A30, 0x000000000, 0x00000002) nvlddmkm.sys - address 8E4F1A30 base attempt 8T413000, Date stamp 460764B5" Sometimes when I reboot it just sits at a black screen without ever even showing the DELL logo/loader. I have to hard reboot and turn the laptop on again, hoping that it will load Windows. I'm now in Safe Mode with Networking and only browsing the internet; the problem hasn't arisen while in safe mode. I've scoured the internet about the nvlddmkm.sys problem and it seems to be incredibly prevalent with Nvidia users. There are tons and tons and tons of suggestions and "solutions," none with a tremendous or reliable amount of success. Some people swear it's a hardware problem and nothing software related, others swear just the opposite. Some claim it's a registry problem, but most people who have the problem haven't found any solace or solution from this affliction. I'm on a fairly fresh CLEAN install of Windows 7 (about 4 months old). Nvidia GeForce 8400M GS, driver set 18.104.22.16862 Intel Core2 Duo T7300 2.00 Ghz Windows 7 32 bit Any ideas/suggestions?
