PC can't connect to internet post-lightening, laptop can

Hi and thanks in advance, A lightening strike hit us recently (last week) and fried electronics in the house. The next morning we didn't have internet on either our PC or Apple laptop. The modem wasn't doing its blinky green light dance. I used a multi-meter; the power supply was dead. I replaced it. It did its blinky dance. I turned everything on in order; turn everything off, turn the modem on and wait, turn the router on and wait, and turn on the PC and laptop. The good news was, the laptop got the internet, albeit much more slowly and intermittently than it used to. The PC got nothing. I've fumbled around with this for a week and can't fix it. I'm not sure if what's wrong is the router, modem, or something specific to the PC. Time Warner reported the internet is getting to my location (I called). They said the router was the problem and, consequently, not their problem. I tried connecting the laptop to the modem directly, leaving the router and PC unconnected. This works (I get the internet on the laptop, still). I tried connecting the PC to the modem and leaving the laptop and router unconnected. This *doesn't* work (I get no internet on the PC). Device manager shows that my ethernet card works. I tried sending a test packet to the modem. This also worked.

Another unrelated issue, for bonus points if anyone knows-- my computer boots up and is black screen until Windows login. Is this a new Windows feature? How am I supposed to access BIOS? It's always done this, since we've owned it. Can only guess it's a feature? Anyway, any idea what I can do to narrow down the problem and fix this? Thanks very much, I appreciate it.
