rebooting while playing videos or netflix

The 3.3, 5 and 12v values are way too low.
Likely the cause of the reboots.

For now, forget about drivers, programs and event logs and focus on increasing the voltages

Axe0, if you need some help, please let me know. But, ATX Standards are that the rails must be +/- 5% of the rated value. The best place to get the voltage readings in in BIOS. They are much more accurate than software. If you need some help, let me know. But, don't confuse Volts, Amps and Watts. They are different. You can have a 1000W PSU, and your computer can pull only 300 W, but if the +12V only puts out 10V, your computer will not run well, if at all.

Found event viewer

I took some screen shots (don't mind the kids watching a show on the second screen). What should I be looking for?

I'll hold off posting the error log stuff until you can check some voltages or unless you want me to post it anyway just for future refernce but if your mainboard is acurate you are definitly undervolting and a video card playing a video and the CPU will need the correct volts and current .

I was thinking you might be right ( if the mainboard is reporting volts accuratly ) the PSU rails all look way to low like you say while the CPU volts are barely in range they could certainly be a lot higher even at stock clock speeds as well .

A Digital Volt Meter would be nice to confirm undervolting and also to check the voltage at the wall plug in case there is a bad connection or wire nut in a junction box or the outlet box or a fautly surge protector or F.... up board ?

I had to re wire a couple of houses I owned trust me they can do strange things on any given circiuit with something as simple as a bad wire nut some where in a daisy chained circuit in a junction box ,switch box or outlet box anywhere along the chain for that circuit .


Maybe before we get too far along try the PC plugged in directly to the wall outlet if it isn't already maybe its a bad surge protecter strip or to many things on one strip ? .

OP (origional poster) mentuined he had a TV , a monitor and the PC (probably powered speakers also ) I would put the PC straight into the wallsocket with its own surge strip if testing bears that out and the rest on another strip or maybe something like powered speakers on the same strip as the PC but maybe not those can have noisy wall warts or maybe run an extensiion cord for the PC into another circiut in another room or hallway and see what shakes out ? Then if it shows the room circiut is undervolting get after the wire nuts ,breaker or call an electrician he might have a resistive (faulty ) breaker also but not bad enough to open .


As you know when the CPU ( processer ) and GPU ( video card or chip ) are playing video especially HD they will demand volts and currents well above surfing a web page or typing an office doc .

I'll hold off posting the error log stuff until the OP can check some voltages or put in a known good PSU or unless he wants me to post it anyway for refernce ..

Maybe OP got bad luck having two bad PSU's but it can happen or maybe its not getting the right AC volts from the wall outlet or surge strip being common to both PSU's and all. ???

Good points specially about the BIOS I never thought of that . OTOH a cheap or faulty 1000 w PSU can undervolt just as easily when it only needs to put out 300w like you say .

I sure will do essenbe :)

That is what I thought after our last conversation about test software, but I wasn't 100% sure.

@blutos cousin, lets first focus on the PSU before we check the software, logs and other stuff :)

@copracr, for the reminding.

Please post a photo of the 3.3v, 5v and 12v in the BIOS.

How come I didn't think of that ?

I don't know, but with a sudden reboot/shutdown the first step is to determine if the power source (battery/psu(bios voltages)) has problems
