Been contantly getting blue screens and need help to get rid of them. My laptop is a P-6831 FX with nvidia 8800 GTS graphics card with 250 gb hard drive and core 2 duo T5450 on Windows Vista Premium. Bought it from Ebay and has been throwing blue screens since I've received it. I've reformatted and used memtest. Memtest showed no errors in 9 passes. Still receiving the error messages. Here are some dump files that I've recently received. Uploading dump files as soon as I winzip them.
