Maybe try monitoring your system using software to see if there are any variations in normal operating temperature? If you're worried about your hard drives, you can run a health scan to see if there are any bad sectors, or if the unit is going to die outright. Have you been noticing any throttling or unexpected shutdowns?

What version of the 290 do you have? What is the model number? There have been issues with the fan curve with the new crimson drivers, but since you have it pegged to 100% it could actually be one or more of your fans.

What games is it affecting you in? Do you have any overclock? You might just be better with rolling back to the previous AMD driver. Crimson has HUGE issues with it.

You could do that too. It's just the 4+2 phase boards sometimes have issues with FX-8xxx and FX-9xxx chips.

Usually, if a power supply is at fault, you'll receive the IRQL_NOT_LESS_OR_EQUAL error in windows.

Prebuilt with problems = immediate return

The CX PSUs have problems with higher end cards, not a gtx 760.... The CX600 is almost overkill for it...

If you have a extra fan around, try pointing the fan at the mosfets on the motherboard and see if that changes anything. You don't have any overclocks applied on any of your components, do you? Make sure your hard drives are alright by downloading crystaldiskinfo.

"Lack of originality"

http://crystalmark.info/software/CrystalDiskInfo/index-e.html I would use cyrstaldiskinfo to see the wear/life of my hard drive. If that's alright, I would then turn my attention to the fan. depending on how obnoxious the noise is, it could be a problem. It could also be something that could resolve itself as well. If you purchased it recently, you could always try taking it to the place that you purchased it at and have them take a look at it.

I hope you're not trying to run your 780 TIs in SLI right now. there are still major issues. You're better off running the cards individually for the time being until they get things straightened out. There is supposed to be a patch coming this upcoming week that will "fix" things. Not too sure what this will involve exactly however.

The tp300la has a fan right in the middle of the notebook that is spinning 85% of the time. It would be either that or the HDD you have in your notebook is getting ready as well. The hard drive is on the right hand side after you flip your notebook. It's 99% one of the two.

15.11.1 is the fallout 4 driver. It's the newest beta driver. It reduces CPU overhead quite a bit. Make sure all your temps are in check as well.

Specs of your PC? Latest drivers?? What are your temps like?

Well, troubleshoot the problem to begin with. Pull the cards and just run on the iGPU. Then plug one card back in a time in the top slot. If they both work individually then you'll still good. Just do what you can before you start shipping parts back because you think they're bad. **EDIT** Make sure you reset the motherboard as well. Unplug the unit, push the on button once or twice. Remove the cmos battery for a while. Put the battery back in, plug it back in and try to start. Make sure your memory are in the proper slots and firmly pressed it. Also, make sure that all your psu connections are plugged in properly as well.
