Ever since the Minecraft 1.8 update, I haven't been able to load
Minecraft. I've tried in browser and from the launcher. I've deleted
.minecraft, uninstalled and reinstalled Java, and deleted all my mods. I
tried in Firefox and Internet Explorer. It still doesn't work.
Essentially, what happens is, in the browser, the updating minecraft bar
appears, almost completely loaded, doesn't finish loading, but
progresses. At which point it moves to a white/black screen quickly
followed by a dark grey one (this is just on the game, not the whole
computer screen) and I cannot play. Sometimes the the screen that says
Mojang appears, and I suspect that may be the white screen. Also, one
time I reached login screen but it crashed soon after.

When I play via the launcher, I login, and force update or not, then the
Minecraft screen, after updating, turns black, and crashes.

Other Java related things work fine, like I can play RuneScape and Minecraft Classic.

I can also get on Minecraft fine on other computers.

EDIT: I just tried to raise a huge minecraft world in Classic, and it
grey screened. However, I was able to raise a small one. And going on a
multiplayer server crashed Firefox like from the launcher.

There is also an error, from the webpage, instead of a grey screen, as follows:

Did you have any mods installed when you started the launcher or web client?

No

No, as I said, I deleted all my mods.

Antivirus

I researched this and found Norton linked to this issue. By any chance are you using that anti-virus software?

I'm not using the anti-virus

I'm not using the anti-virus software, but I did a search and I do have the "Norton Field Guide"

Well

If Norton doesn't seem to be the problem I'll keep researching.
