Wasn't sure where else to put this.

Yesterday I came home and my computer had frozen. No blue screen, just frozen on the desktop. I reset the computer, and it took an unusually long time to start. I finally managed to get it booted in safe mode, but it seemed to take forever loading crcdisk.sys. There was major performance degradation in speed, tested by loading up some intensive games.

So I decided to reinstall windows and just be done with it. I reinstalled, and am still having the same problems. It takes an unusually long (10-15 seconds) time between the windows loading bar on posting and actually popping up the login, during which the screen goes black. Its also slow once you're in windows (in fact it just hung up twice for a while as I was typing this), and it won't launch some executables, like the install program for the Witcher. It's also not letting me update the video drivers, saying it "cant connect to the nvidia website", but continues trying to install thru the driver autoinstaller. Both hard drives are relatively new (within the last 3-4 months, and 1 is less than a month old even)

I'm hoping this isn't a major hardware problem. I'm running Vista on an i7-2600k, with an 1157 chipset board (dont recall the exact model but its an Asus), and a GTX 970, with 8g ram and a 700w psu.

Any ideas?

You can make a usb version of memtestx86, get the free version.
If you install the new RAM for testing I recommend clearing the CMOS and then go with whatever the SPD comes up with.
Good luck and lets us know how it goes.

I ran hard disk check on windows and it didn't seem to show any errors. can I install memtest to a usb and boot it from there?

I actually work at an electronics store and brought home some new ram. If i switch the old sticks out for the new ones, that'll quickly tell me if its a RAM issue correct?
 

Correct! and take a look in Windows Eventviewer as well. It might show related errors in the system log.
