Hi, I bought a new laptop and it has a problem i discovered. I cannot return the laptop as it already past the returning date (30days). The problem is discovered last week after i installed lots of games. My laptop crashes at full screen mode on any games i installed. At first I blamed the game, but after installing lots of games and tried every single one of them (age of empires3, medieval2tw, COD, black and white 2, red alert3, etc.). After this, I also tried to use some 3d programs like the ones built with the latest Nvidia SDK with Direct3d 11 and still crashes. The crash (to be specific) is almost a crash to desktop (CTD) BUT, weirdly, it loads itself back and then loops again more like alt+tabing when ur in game(it's not sticky keys). However, the 3d programs like the one in NVIDIA doesn't ''alt+tabs'', it's a complete crash and the windows will then try to resolve it (which fails). It's a bit powerful laptop and here are my specs: Windows 7 Home Prem 64bit Core 2 duo t6600 2.20ghz 4gb ram ddr3 1gb Nvidia Geforce gt 240m Supported by PhysX but Games requires DirectX so I installed it. Would it clash? I dont think so, coz you can turn off the physX gpu. and i tried that. 1tb HDD Now, the things that I have tried are: Update/install my video card driver, chipset and was going to update my BIOS (which is the latest so that's why i did not). Installed the directX 11 (SDK), and even tried the Direct x 9.0c. I even clean up my system by reinstalling windows and everything. I don't think it is a compatibility issues as I've played these games on a different laptop with the exact same system (my first laptop before, I exchange it for it is has a faulty keyboard and same windows) As you can see I am getting bad luck from where I bought my laptop. Yes, it is a refurbished laptop from a big name retail store. I already contacted the Manufacturer and they couldn't help me because it involves third party software. However I told them that I highly believe it is a hardware issue and the sick bastards replied with: ''ask for advice from your local technician.'' Wth?! I well try to settle a score with them tomorrow but for now, I want your expertises.
