How do you boot from USB stick?
Here's an Apple article:

But it seems a lot of effort to get it done.

So if you have to have OSX installed on the USB device, then the only point of booting from it would be to repair an OSX installation on the main hard drive.  This solution doesn't expand the diagnostic capacities of OSX in any way.

Well, I downloaded a copy of that CD you mentioned, maybe I can get it to boot.  Fingers crossed.

I believe the idea was to install Hirens Boot CD to the USB drive, to perform diagnostics - not OSX itself.

According to that article, though, a USB stick has to have OSX installed on it to be bootable.

It's worth a try?

Can't Macs run Windows now anyway?

I used to have the same macbook pro. The GPU's in those are notorious for failing. The lines you are getting may be because of GPU overheating. Unless you're hitting 100*C browsing the net, it can be pretty normal on that laptop, mine would always hit 90*C playing 1080p movies. And idling 50*C - 60*C was pretty common on the first gen mbp conroes.

Are the fans running at 2k rpm, and do they speed up when it gets hot? A problem I noticed with mac laptops is that depending on what program you're using, its usually a hit or miss where the fan will turn on when you hit higher temps. There's a few program that let you mess with the fan (SMCfancontrol I think its called.) For example, with VLC the fan pretty much never speeds up even though the CPU may be frying... or maybe fans just turn on too late, like 90*C.

Also, with your posts over the years I have noticed a trend in how much you like firefox. Why would you use it on OSX though? I used to use it for work (web dev plugin), but Safari and Chrome are faster by miles. Unless you have a SSD, firefox starts very slow compared to the other browsers (and scrolls like shit on OSX).

I used to have SMCfancontrol installed, but I never noticed it having any difference.

Also, I really like Firefox, for a number of reasons.  It's a good project, from a good company.  It has a ton of neat plugins and addons that I use a lot.  And it's better for porn.  But I have noticed how slow it is to start up, and how long it takes for it to dump its memory on shutdown.  Lately, I have been using Safari a lot more often, and I like it for some things, but there's some behaviors I just miss too much.

I just got a 13.3" MacBook Pro. The fans are silent so far, but I have it on a usb powered fan pad for ventilation.

Have you tried using that SMCFancontrol to manually turn up the fans to 100%?

Now I can hear them. Just under 6200 rpm. The temp dropped 25C to just above 60C.
