> I tried deleting hiberfile.sys since I never use hibernation (I'm on a desktop) by doing "powercfg -hibernation off" in the Command Prompt
It worked for me when I used capital letters for the option, like the help file says. Go figure. That also deletes hiberfil.sys

Well for one thing, get it the hell off c:
But you can make lemonade from lemons (or whatever the saying is). Get a 64-bit RAM disk program that allows you to make an 4G ram drive and put the paging file there. Word on the street is that 7 has one available for free now, but I have used Winramtech Ramdisk Enterprise 64 for years and I love it. Put the temp files there too.
When you do, boot happens astoundingly faster. The "welcome" screen just flashes on the screen for half a second before I get a desktop. Apps that use large temp files are much faster too. Being a speed freq, I also put all my browser cache files there. (I have 50 Mbit for the hell of it, and the once-per-browser-session read from the web server is unnoticeable.)
☞ Do NOT believe those know-nothing non-Jedi who say that Windows' crappy memory management will automatically use all your RAM before it uses the swap file!
This is NOT true, as you can see with a utility that shows swap file I/O, like taskinfo (which is both excellent and free). Just now, I looked and saw about 1,000 page faults/sec (which do not all involve the swap file), and about 300K/sec of page file writes (which DO). When I'm actually doing anything, swap I/O is even higher.
You can also watch the sanguine little drive activity light. It blinks all the time, but rarely blinks when paging, temp, and cache file I/O all go to RAM. I keep the 2G of Google Earth cache files on disk because they're so large, but modulo that, I'm always on the lookout for data structures I can divert into memory.
For example, I also set my download directory to be on the RAM disk, too. Almost everything I download (other than po rn) is either zip files or run-once installation files, which you otherwise have to delete. Oh, and those installs run twice as fast, too—without fragmenting your HDD (though of course, with an SSD, fragmentation doesn't matter).
Of course, that huge paging file no longer uses up your SSD. But you have to remember to delete it after you've moved it's functionality to RAM.
Whatever windows is doing with the swapfile, it does it much faster when its done to RAM. And BTW, I wrote the memory manager for a commercial computer language (in assembler, not C). I know whereof I speak.
ALSO: in your case, get another 8G of RAM. Then your temp files can be truly righteous. Try editing the boring "talk" parts out of a 2G nubbin-rubbin' vid both with and without the temp files in RAM. It makes so much of a difference that I upped my RAM to 32G. Now, ANYTHING fits in memory.
And paging to RAM doesn't use hardly any RAM, because you set the minimum to be 128M and the max to be a little less than the size of your RAM disk (to allow for temp files). And don't believe Microsoft when they suggest 3 or 4 times your memory space for paging. Even when I only had a 4G RAM disk, I never even once ran out of virtual memory.
And finally, I hear that games do a whole lot of virtual memory thrashing. I bet this would speed up gaming a LOT, though I wouldn't know. I never played a 3D game (except second life) because they all involve slaughtering people. What a horrible, horrible thing! Why is that fun? I'll never understand guys. Or, for that matter, humans.
