odd computer problemFollow

ive been having some weird computer problems with a friends PC. i recently built him a PC for FFXIV and as far as i know everything is fine because i re-checked everything three times to make sure i didn't miss something.

the problem is, at his house, the computer randomly restarts (not shut down) every 10-20 minutes or so. the odd thing is, at my house i can do whatever i want on it and surf the internet and the computer doesn't restart.

now, awile ago i did sell him an old LCD computer screen that if the plug from the computer to the screen wasn't plugged properly it made lag on the computer and some other minor weird stuff. i haven't tested any other screens yet, because i would have to bring my own and the way i have myself set up it's a pain in the *** to plug/unplug things.

so what i would like to know is your guys/girls opinions, and if it's possible the screen could make the computer restart. if the answer is yes i guess i'm going to have to not be so lazy and try mine.

I suppose that in some weird way the monitor could in theory effect the PC and force a reboot. However, is it possible that the amount of amps going from the outlet to the PC is not enough to handle the draw the PC requires? After 10-20 minutes he ould be using enough system resources to hit its peak power consumption, and if there isn't enough power the PC would most likely reboot to avoid some kind of fatal error or whatnot. I guess what I am saying is, is the wiring in your friends house old and yours new? Just something to think about. Welp, that's the only thing I can think of, hope you figure it out.

hmm come to think of it, my house isn't very old, and his has been around for awile. if that is the case, is there anything that can be done about that? would changing the PSU in his computer change anything? because i have better spare ones.

Ok, so it seems as if a lot of old houses were wired using 14-gauge/15-amp wiring. I am not an electrician, nor do I know a lot about how electricity works, but I am thinking that modern-day computers' PSUs are design to pull in 20-amps(that's how much modren-day wiring uses) and then do whatever it does to increase the amperage to whatever components need however much.

This is just speculation, I just remember having an apartment one time in an old house, and I had to plug different electronics into different outlets (sometimes in separate rooms) because the individual circuits couldn't handle the load.

I hope that this isn't the problem, cause it's expensive to update the electric in a house.

Well here's hoping someone who had a similar problem see's this thread, or maybe an experienced electrician that knows about that kind of stuff.

Most modern day homes still have 15 amp service to most outlets unless specifically designed for the 20 amps. Look at the plug, -|| is 20 amp, whereas || is 15 amp.


Just to clarify from a handyman:

Most PSU's actually use 15 amp service in the US. The exception is the 1200 watt and above which require 20 amp service. Even then, if you are pulling all 15 amps, then you would have a breaker/fuse pop and need reset/replaced. (You also need a new PSU)

Yes, the screen could potentially affect the computer, but not likely.

Have you checked overheating? Also, how about the ethernet cables, etc. Sometimes bad cables will cause this.

Right Click "My Computer" > Manage
Go to Event Viewer > System

Any system errors should be listed in here. Anything that would cause a reboot should be listed in here as well. Look for red X icons near the times of the restarts and they should give you some info.

I'm leaning towards power issues (Is he using a surge protector? Is it a good one?) or overheating most likely. I can say with 99.999% certainty that the monitor will not cause the system to shut down.

As for cables, the only external cable that could cause this would be the power cable itself. Ethernet, keyboard, mouse, etc wouldn't cause this.

First think:

- Go to "Control Panel" > "System" > "Advanced" > "Start up and recovery" and unmark "Automatically restart"

Now, when the error occurs you will see the blue screen with the error that is causing you computer restarting.

Post the BSOD message here and we can try to help more.

Maybe the RAM? Easy check with memtest. The PC I built for FFXIV kept rebooting in December and it ended up being one of the sticks of RAM. Once I took it out, the rebooting problem stopped.

ill uncheck the restart option, and ill see what kind of errors i get. ill also check what errors ive already gotten. i dont think it is the memory because the computer only doesnt work properly at his house. at mine theres no problem, although my wires/connections are all good. ill check his out when i go there tommorow

amyway, thanks for the replies guys hopefully one of these things fixes my problem.
