No BSOD, but PC did restart itself, and did produce a bug report.

Here is what it should look like. I suspect your GPU is bad or just a little under powered. It could cause BSOD trying to run beyond its abilities.

Ok, good feedback.

Please complete the recommendations made by Arc in post# 2. Do each in the order given and provide feedback (screenshots, log files) where requested.

Here's a To-do list, the full instructions are in Arc's post# 2.

1) Speccy - Publish Snapshot of your System Specs .

2) Check the Power Supply Unit (PSU)

3) Done: ~~Stress test the Graphics Card using Furmark~~.

4) Install the NVIDIA DRIVERS
.

If my GPU is underpowered, does it mean I should unplug one or two devices from my power surge block?

Is there a tutorial for checking the PSU on the calculator? It's a bit difficult finding the information for the drop-downs.

By under powered I meant old, and not up to the task of modern gaming, it's well over 6 years old. It has the older GDDR3 memory, newer ones have GDDR5. Having only 512MB is holding it back too.
Unplugging things won't help. Speccy also says it's interface is PCIex1, which slows it down, one lane of data. GPUs should use the PCIex16 slot for 16 lanes.

That said the GPU may not be the cause of restarting or freezing.
You can test your PSU using this: PSU - Test DC Output Voltage

HWinfo can read volts while under Windows too. Use the bit version for your system, run it in Sensors Only mode. HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools

It has some strange values I've not seem before, but may be due to it being an Apple machine.

I only see the 12V, which is fine. Does yours show a section similar to this?

It also looks like your CPU and GPU temps are a litter hotter than they should be, but not dangerous. Are you running something, such as a video or scanner?

Actually got a blue screen error! Sorry for not reply in a long time. Decided to get a new PC, and one that I will build myself.
It would be nice to solve the Mac's problem, regardless.

Also, Mac OS lags a ton. Windows 8 is remarkably faster. Yes, this is on the same Mac.
