OK - the filename isn't the source of the error - it's where the error occurred. For example, if a program addresses your video card in a bad way - it'll cause an error in the video driver (the nv4... file). The same goes for the win32k.sys error. (But, FWIW, when there's an error with an nVidia driver I ALWAYS update the driver. The reason for this is that the drivers seem to get corrupted fairly easily by rogue programs - and updating them gets rid of the corruption).
So, here's what we do (based on this link (which is the referral link for your last error message): http://www.osronline.com/ddkx/ddtools/bccodes_59k7.htm
First, make sure that all of your hardware and software is on the Windows Hardware Compatiblity List ( http://testedproducts.windowsmarketplace.com/
). This is a long list, and there is a lot of stuff that's not on it. My general recommendation is to not bother with any major, brand name hardware that you have. Concentrate on the off-the-wall stuff that you might have. Your hardware not being on the list doesn't mean it won't work - it just means that Microsoft won't guarantee it.
Next, update your video driver by going to the nVidia driver site: http://www.nvidia.com/content/drivers/drivers.asp
and select the appropriate WHQL certified driver for your video card (WHQL is needed during troubleshooting because it's been certified by Microsoft to work with Windows). The by-the-book solution is to disable the driver to see if this fixes the problem (and stops the BSOD's) - but I find that updating it usually fixes it.
We can work on other drivers as clues present themselves.
Do you have any 3rd party remote control software on your system? If so, please remove it during the troubleshooting. Some of these programs are known to cause problems with win32k.sys (and if they're video remote controls they may also affect your video drivers).
The above are the most likely causes of this problem. But, here's some more things to check - just in case:
Make sure that you have plenty of free hard disk space (I recommend at least 15%).
Test your memory using one of these free, floppy-based memory testers (run it for at least 2 hours - but overnight is better):http://www.simmtester.com/page/products/doc/download.asphttp://oca.microsoft.com/en/windiag.asphttp://www.memtest.org/http://www.memtest86.com/
Also, check in your BIOS to ensure that any BIOS or video cacheing or shadowing is disabled.
Let us know how this works out!
