Power Supply Info
The following issues are signs your power supply might not be up to the task:
1. During boot, your machine takes a very long time to get past the POST screen
2. During heavy graphics use, you start getting hard drive errors. The hard drives and the video card both live on the 12V rail and thus if the video card starts pulling too much power it can cause hard drive errors.
3. Memory errors in programs, but when you test the memory it tests clean. This is a similar issue to the second one. The electricity in a computer has to maintain a certain flow and that flow is used to run the memory. If that flow starts spiking around, it will cause memory errors.
4. Random shutdowns and reboots during CPU intensive activity. Like the memory, the CPU has to maintain a certain frequency across its calculations. That frequency is directly related to the voltage the CPU receives, and if this voltage fluctuates too much, the CPU will fail just like memory will. When memory fails, a program will crash, but when the CPU fails, the whole machine crashes.
5. Hangs during boot where POST never even comes up that can then be fixed by resetting the computer, sometimes multiple times. This is the same as the POST problem, where the hardware isn't getting checked properly and hangs while waiting.
6. Your computer starts to boot, but then just shuts down, or gets locked in a loop of constantly trying to boot.
