  1. Hello, I've recently ugraded from Vista 64bit to windows 7 64bit. I used to have bluescreens several times a week and didn't really follow through trying to get them fixed. I thought upgrading to 7 would get rid of the bluescreens but after the install 3 days ago, I've bluescreened several times, 2 of them having to do with ntfs.sys and the latest one having to do with ndis.sys about 10 minutes after the latest ntfs.sys.

    I have 4 gigs of ram, an ep45-ds3l motherboard, E8400 @ 3.0 GHz and an ati Radeon HD4800 series (i believe the 4850).

    The last 2 times, maybe even all 3 times, I believe I had Firefox open, Windows Media Player running/playing on mute, Skype open, and Microsoft Security Essentials as my antivirus. The last 2 times I was watching a flash video.
    3 dump files attached.

    Your issue is memory corruption and we suggest you run the free and safe Memtest on your RAM.

    See the link below and follow the instructions. There is a newer version than what is listed; use the newer. If you need to see what the Memtest screen looks like go to reply #21. The third screen is the Memtest screen.

    Step1 - Let it run for a LONG time. The rule is a minimum of 7 Passes; the more Passes after 7 so much the better. The only exception is if you start getting errors before 7 Passes then you can skip to Step 2.

    There are 8 individual tests per Pass. Many people will start this test before going to bed and check it the next day.

    If you have errors you have corrupted memory and it needs to be replaced.

    Step 2 – Because of errors you need to run this test per stick of RAM. Take out one and run the test. Then take that one out and put the other in and run the test. If you start getting errors before 7 Passes you know that stick is corrupted and you don’t need to run the test any further on that stick.
