Windows 7: Multiple BSODs, Driver_IRQL_not_less_or_equal etc.

Windows 7 Ultimate x64
Multiple BSODs, Driver_IRQL_not_less_or_equal etc.

So, my bluescreens are back.
I've previously run the SeaTools hard drive diagnostic program and all three of my hard drives have passed which more or less rules them out. I've run Memtest for only about 10 minutes but haven't come across any errors. I'll run it overnight tonight though to be perfectly sure that the ram isn't the problem. I also haven't been able to recreate the errors by doing anything specific. They'll usually happen at any point whether that's rendering a video with After Effects, browsing Google Chrome or just using Skype.

Also, I ran TDSSKiller and it came up with this:

Are any of these bad? What could possibly be causing these bluescreens?

After looking through other threads, I decided to stress test my PC by running Prime95. My CPU speed is set to stock.

Try using a genuine Windows 7 Installation for starters. You are running an ACER OEM on a retail motherboard which can only ever report as genuine if a hackers activation crack has been used.

But surely even if my copy is genuine, it wouldn't interfere with the Prime95 results?

I've installed a legitimate copy of Windows XP on another hard drive and downloaded and ran Prime95 and have recieved the same errors.

Edit 2:
Found a solution to my problem. Both of my ram sticks were different makes which were conflicting with eachother.
