Crashing with Multiboxing.

[Bollwerk]

The way I would approach the problem is starting out by running 1 wow for 10+ minutes, then 2 for 10+ minutes, etc... until you figure out which number of wows is the breaking point.
Also, if anything is overclocked at all, reset everything to stock speeds, just to rule it out.

do you use 1 or 2 monitor setup? also, if your system crash, make sure to run it without OC (CPU/GPU). I bet, that your problem would be with your system overheating. Download CPUID HWmonitor and check all the temperatures and fan rpm, you can also view the state of your HDD.

I suppose I will have to try that. I set my Processor speed down to a VERY stable setting, but it still crashed after about 10 minutes with 4 accounts up, I dont want to reset my BIOS, but I guess it's my only option.

How old is the power supply?The older they get the less power they put out. From what I could find it has 4 rails for power out put-you should get get a power supply with a single rail-there is a formula somewhere(can't find it right now) for how much "power loss" there is with multiple power output rails.
