Thank you for taking time out to clear up things. I will try with an increased pagefile again to see if I still get BSOD. Probably that also has to do with the problems encountered after removing the extras.

Increasing pagefile was not precautionary; when going to reset it, I saw Windows was at default of 4025 MB, and recommending setting to 6027 MB; I then at first thought to set it at 12GB (3X installed RAM), but found scaling it back to what Windows recommended (6027MB, 1.5X installed RAM) works just as well in keeping away BSOD from CIS (though older versions of, say, GMER can BSOD but from poor handshakes while reading registry policed by CIS/other anti-malware, ala race condition).

Per my router, it’s an ISP-provided SMC Networks router with internal “aerial”; it doesn’t even appear at SMC website last I checked, so probably old stock! However, interestingly, somehow my ISP has ONE way of accessing and setting routers/modems (and “stealth ports” is always chosen/saved at its gate installed into ANY router); here, it won’t matter how I upgrade router; at best, ISP answer if any is usually in nature of “um, a glitch, we’re working on it” (BTW, they used to have ipv4/ipv6 Teredo NAT tunnel, but since last Winter offer only ipv4, saying ipv6 will be back by next Winter. In light of PRISM, one might conjecture that until MAC addresses over ipv6 here are traceable, somebody needs to tap in and see if your MAC matches what goes out from your IP…but that’s conjecture as to cause. This “3 ports closed” at router has continued even after clean erasing/re-installing Windows, and no other partitions are active, so it’s not coming from PC malware infection.

My last “windy” comment: you’re so right about software outpacing older units; the Acer 5736Z dual core with 4GB RAM/2.30GHz CPU, made 3 years ago and which I’m commenting from, could even load and use full Autodesk Maya components and dependencies, as well as other prof-grade art/video/photo/GFX softwares…today, it still has a few abilities while evolving VFX/GFX software requires more power, but it would cost more to convert PC to NVIDIA/Intel supercards and such than it would to buy new units already at state of the art.
