If it's not all of the computers, I've seen problems associated to power
supply malfunctions and voltage regulator malfunctions on the motherboard
that can cause blue screens.
Usually, they are intermittent if it's a blue screen. One of a memory block
voltage regulator and it killed the computer every 20 minutes, 45 minutes up
to as long as 2 or 3 days. I had an ASUS Motherboard that was doing that,
and they come with software to monitor the voltages and temperatures of the
CPU and motherboard. I noticed that whenever it crashed it was preceded by
a voltage drop in the memory's voltage.
The second time, all of the lights came on and the computer would boot up
at all. The power supply had a bad capacitor and couldn't produce the
required current. So, the whole computer seemed to turn on, you'd get the
hard drive lights and all of the lights on. Once, I replaced the main power
supply, the whole motherboard was fine.
The first took longer than the warranty to figure out, and the second was
easy. If it's the only computer having a problem it's probably static or
dust that got to the voltage regulator in manufacture and you're looking at
an intermittent problem. All of the rest work, and changing the main power
supply might fix it. But, if it doesn't, then it's probably a voltage
regulator on the motherboard. Just send it back and ask for a replacement.
