Please boot to safe mode and use the Norton/Symantec tool found here to clear your machine of all of its files. I see you have since removed the software in the normal method. This will ensure that all of its remnants are removed as well. I recommend installing MSE as the antivirus since it will never bsod on you and is excellent on resources.
2) Use Memtest86+ to test the memory overnight. If you're also up to it, it could be run on one stick of RAM at a time, while all others are removed. This is the best way to single out any defective RAM modules.
I would also make sure that the bios is set manually for the RAM timings, frequency and voltage that the manufacturer's website shows. Use CPU-Z to get the exact memory module brand/model.
Hello, I done the memtest on 1 stick of ram and that came out o.k, But with the other stick of ram in by it's self it won't even bring up windows, It goes into repair but won't find problems the bar just keeps moving, Im going to replace the ram and see how it goes from there, Thanks for your help.
