computer not booting properly

[X-13]

We've got a couple of machines that are having issues booting properly. They're getting to the Wondows logo screen and then refusing to do anything at all. [the logo doesn't even load.]

 

Restarting the computer [forced off, load normally] fixes the problem.

 

 

I've just tested on of the machines in my office, and it's booting fine. [currently up to 4 boots in a row with no issues. In-class it fails every you boot normally.]

 

So, here's my question...

 

Could a lack of power cause a computer to freeze during boot?

I am not joking but take it back into class and give it a whack on the side nearest the fan... that will sort it out we have this all the time with some machines in our ICT Suite... quick wack or a blast with compressed air seems to sort it out.

These are 2 BRAND NEW machines.

 

I aint whacking them.

Are they wired or wireless? You say they work fine in your office? Is it a connection issue - something in these new machines that is more sensitive to fluctuations in the wireless or whatever?

They're both.

 

Connected via cable for stability, though.

 

And the test machine is disconnected. I'll reconnect it and give it a try, but iirc the one in the class has been fine while I was sorting it out in my office.

Yes X-13. a lack of power could cause booting issues. We had a suite here that had issues with the PCs freezing, more so when the room was warmer in the summer. Upgrading the PSUs eradicated the issues.

I wouldn't have thought that would be the case with new PCs though.

It's new electrics as well. Could be a bit of dodgy wiring.

If the power is fluctuating too much, then yes in theory it could create problems. I'm speculating that the power in your office is either not new or is on a different circuit? It could also be a load issue too - 10 PCs work fine, but then 15 PCs is a little too much for it.

My office is just as new. Maybe slightly older. But it's in a different building.

 

I also have more stuff running in my office that there is in the class...

I'd maybe suggest asking the electricians to come back and double check everything's OK.

That's the next thing I'm doing after I try it disconnected.

is it worth trying it back in location as is see if it can be replicated if so start turning all other plugs off see if it helps?

It's really heavy...

Have you tried a different, working computer in that location?

Only a laptop, and that's fine.

Tried different network ports?

Tried different network ports?

 

Yup, and I tried it purely on the WiFi.

Could be cold boot power issues, BUT you would normally fail POST not get into windows loading area.

 

I would swap a working PSU with one thats playing up and see what happens.
