The various BSOD messages, when taken as a whole, may indicate something that the individual message doesn't.
For example the STOP 0x4e message (the PFN...) says it could be drivers or memory. http://aumha.org/win5/kbestop.php#0x4e
Whereas the STOP 0xD1 (the Driver IRQ...) says it could be drivers or memory also. http://aumha.org/win5/kbestop.php#0xd1
But there's also mention of the pagefile in the STOP 0xD1 error (and the STOP 0x4e is about the pagefile). And the pagefile is also affected by the condition of the hard disk.
So that leaves you with 3 possibilities that have been confirmed by separate error messages.
Now, if there's a filename associated with any of these errors - it could help us to narrow down the search a bit. But, without it, we can suggest a few tests that will narrow this down even further.
1) Use this free tester to test your RAM: http://www.memtest86.com/
Follow the directions carefully, and let the test run for at least 2 hours (overnight is better). But, if you start getting errors you can terminate the test because you'll know the memory is bad. If you've got more than one stick of memory, you can run the tests on the individual sticks to see if more than one stick is bad.
2) Use this technique to "reset" your pagefile:
a ) Go to Start...Run...and type in "sysdm.cpl" (without the quotes) and press Enter.
-Then click on the Advanced tab,
-then on the Performance Settings Button,
-then on the next Advanced tab,
-then on the Virtual Memory Change button.
b ) In this window, note down the current settings for your pagefile (so you can restore them later on).
-Then click on the "No paging file" radio button, and
- then on the "Set" button. Be sure, if you have multiple hard drives, that you ensure that the paging file is set to 0 on all of them.
-Click OK to exit the dialogs.
c ) Reboot (this will remove the pagefile from your system)
d ) Then go back in following the directions in step a ) and re-enter the settings that you wrote down in step b ). Follow the steps all the way through (and including) the reboot.
e ) Once you've rebooted this second time, go back in and check to make sure that the settings are as they're supposed to be.
3) If both of the above tests don't isolate the problem - then the issue is most likely with your drivers. Which ones? Well, that's a good question. Have you done anything recently to the drivers (such as adding programs that might change any of the drivers)? If not, then here's a sequence to update them in:
a) motherboard/chipset drivers
c) network drivers
d) drivers for any other devices built into the motherboard
e) drivers for any other devices that are inside the case, plugged into the motherboard
f) drivers for any other devices that plug into the outside of the case.
Ensure that you download the latest one's from the manufacturer's website and don't use those on the CD as they're probably outdated.
