Radar_pre_leak_wow64

Is your computer giving you a BSOD??

If it's not crashing/freezing/BSODing - why worry about it?
Please examine the Event Viewer and look for other issues that occur with it.
Please upload an MSINFO32 report:

MSINFO32:
Please go to Start and type in "msinfo32.exe" (without the quotes) and press Enter
Save the report as an .nfo file, then zip up the .nfo file and upload/attach the .zip file with your next post.

If you're having difficulties with the format, please open an elevated (Run as administrator) Command Prompt and type "msinfo32 /nfo C:\Users\Public\Desktop\TEST.NFO" (without the quotes) and press Enter. Then navigate to the C:\Users\Public\Desktop directory to retrieve the TEST.NFO file. If you have difficulties with making this work, please post back.

If you obsess over perfection in Event Viewer you'll spend so much time working on the error that you won't have time to use the system. I don't sweat errors as long as I can do what I need to do.

If I were you, I'd worry more about the errors in Half Life and DAOrigins that cause them to crash.

I did find this: meaning of bucket type RADAR_PRE_LEAK_32?

This looks like an event triggered by Memory leak detection logic. The reported paramaters in this event are the Process name, the version of the process, and the version of the OS the process was running on.

And, here's some links on how to troubleshoot memory leaks:
