Starting about a week ago all of my web browsers began acting erratically when the shockwave plugin is used. I have removed and reinstalled flash and I am still having the same problem. I can't watch youtube videos any more!

Switch to HTML5 YouTube? Don't screw up your compute with viruses and shit.
I think I found the problem. Around the same time I was screwing with audio devices while trying to get Steam chat to work. I think I messed up some sound device that the plug-in wanted to grab and that is why the crashes happened.
In typical Internet fashion as soon as I ask the question the answer comes to me.
For some reason whenever I'm running graphic-intense games my computer completely shuts off 15-30 minutes in. This seems to only happen when I have my firefox browser open.
I suspect that it may be overheating issues. It seems that having my browser open does something to cause this. Anything I can look into?
Try running a Furmark burn-in and watching the temperature graph. If it goes really high and then your machine shuts off, then you know what's going on.
I'm also thinking it could be insufficient power supply. I'm using 750w supply and I have two 1 gb Radeon HD 4750 in crossfire. Is there anyway I can test this?

The problem is certainly not insufficient power supply. It might be busted, though usually if it's broken it just won't work at all. To test for that you'll have to use a voltmeter or power supply tester. Swapping it out with a spare power supply will also work, but it's a lot of effort.
Thanks guys, I'll try these suggestions. One other thing. I remember when I built my comp I moved a fan around in the case. Initially, there was a fan in front, side and back and I moved the fan in the front to the side such that there's now 2 fans to the side and 1 in the back. Could this be an issue?
Also, what is the normal temperature range for GPUs? Mine goes from 100 idle to 130ish in games.
Haha, sorry. That would be Fahrenheit. If its not my GPU overheating then it might be the processor since that would explain why having my browser open at the same time always causes crashes. The extra processing might cause it to overheat. I'll have to check my gauges on the processor temp. What is a normal range for it?

Had a quite surreal experience this morning. So I went to my PC to check my e-mails and look up something. I noticed that it had restarted overnight since it was in Ubuntu rather than Windows (I use my PC primarily for gaming, so I'm mostly in Windows). The reboot wasn't entirely unexpected, since my work PC installed some Windows updates yesterday and I thought the same was happening to my PC.
I restarted the thing but the boot sequences was an absolute crawl. It did the sequence correctly, and the motherboard internal Asus OS also seemed to respond fine (which I checked on a later reboot), but going beyond that the thing was on a snail's pace. For example it took like 5 minutes for it to get to the screen that lets me choose whether to boot in Ubuntu or Windows, and then it loaded in segments and was very sluggish on my arrow key inputs (only went this far because I wanted to see whether it would speed up later in the process).
Anyway, I made a couple more attempts but then I shut the thing down with a long press on the on-off switch and then took a shower looking to try again later. In the shower I was pondering if a hardware failure could be the cause and what it could be. However, when I tried after the shower it seemed to be working fine again.
The PC is on observation for now, whether it does the same thing again. It might have been a problem with the RAM or BIOS as far as I can tell (the RAM because the problem now seems fixed after the PC was without power for a longer time, long enough for the RAM to reset, and the BIOS because the boot sequence didn't work properly). The hard drive seems to be working fine and the boot sequence doesn't even really use it when it started to crawl.
Maybe I'm just talking out of my ass though and/or am overlooking something essential. Any help here?
Running CentOS64 with apache, php, mysql and a few other basic web hosting programs.
One of my wordpress domains continues to be hacked. The first time it happened every header.php file in every theme directory was modified. Even unused themes.
After fixing the injected code I updated WordPress and changed all passwords. I also went through the database and removed all extra WordPress user accounts that were present.
A week later it happened again. Changing all of the files to 444 "fixed" the issue.
Just this week the index.php file in the root WordPress directory was modified. Again I changed passwords and went with 444 on said file.
How do I find the security hole that is being exploited to inject code into these files?

You probably didn't get attacked again. The evil code is probably still just on the server and always running.
I highly suggest you switch to a managed hosting solution where someone else will take care of these issues.
If the evil code is on the server and still running then why are they only going after WordPress? Why is the forum software untouched as well as the database data?
Presumably if they have file system access they can access the WordPress config file and pull the SQL information?
Also how would I track down the evil code that is still there?
I also disabled some of the custom php scripts I wrote just in case they are the attack vector.
I also suspect a hack attempt because every time this has happened it is accompanied by high server load for an extended duration of time. At first I thought DDOS because named was sucking up all my system resources. After I restarted named server load dropped and I found the extra code in the index file.

If that's Celsius, then goddamn, that's not good, something is definitely wrong.
