Watching Movie When Computer Just Shut Down

Hi,

My computer, which I just bought in March, just turned off, as if I'd pulled the plug.  I thought maybe it might have been a power surge but everything else connected to the same power bar didn't short and is working correctly. I push the power button and nothing comes on.

I can only deduce that it might be the PSU.  I've tried removing the battery on the MOBO and resetting it with no luck (there isn't even the reserve power light on the MOBO).  

Any ideas of what exactly could have caused this?

Have you checked the power settings in Properties? If not, right click on Desktop and click Properties. Go into Screensaver tab and click 'Power...' Select the 'Power schemes' to be 'Home/Office Desk.' Then, under 'Settings for Home/Office Desk power scheme', make sure all the drop-down lists are selected on 'Never' as it will make sure that the computer will not turn off after a short length of time.

I hope this helps as this was the same problem for me when I first purchased my new PC.

Sounds like a bad PSU, but first i would try a known good outlet or another known good surge protector and see if it will power on, if it still doesnt power on and there is still no flea power light on the mobo, then i would replace the psu. Since its a newer system it should still be under warranty i would call the manufacture to get the PSU replaced.

Did you buy this computer from a small independent "builder", or was it a full system from a large manufacturer like Dell, Compaq, etc. bought from a computer retail warehouse.

It's clearly under a warranty, but you would have to check a few things in the warranty small print first:

1. Do you have cover where a technician would come to your house and try to troubleshoot/fix it, and if so would you be charged for this call-out if they tried to argue that there wasn't a fault?  You know what it's like, that would be the very time the damned thing would inexplicably just start up again.  Usually before invoking warranty cover, you have to show that you have followed all the steps in the "troubleshooting" section of the user manual or online support.  If you didn't, and it turned out that one of those steps allowed it to boot (ie. checking that all cables were securely socketed), then you would probably end up being charged.

2. If your warranty is a "return to base" one, do you have to pay carriage costs and would the same charges apply if they magically got it to boot without problem after following the troubleshooting steps?  All this is particularly relevant if the computer was purchased online, because I've just been through a rip-off scenario where my request to return a non-functional motherboard took 3 months to "process" and my emails were only answered when it seemed to suit them.  In the end, I ended up paying for the original delivery of a warrantied motherboard which was a dud, and then am left out of pocket after having to pay to send the thing back to them for a refund (minus original carriage costs).

3. What troubleshooting actions would invalidate the warranty?  Check this, because even something like connecting another power supply unit to it to test could invalidate the warranty if the psu wasn't an "authorised" part.  If you are unscrewing anything, watch for thread-locking stuff or a painted on blob of sealing compound intended to reveal if the screw has been removed.  Unless it tells you in the user manual's troubleshooting steps to unscrew something, even that could leave you without the warranty being honoured.

I know this is something really basic, and you may well have tested it already, but have you checked the fuse in the power supply cable from the wall socket?  It's something which is easy to overlook (we've probably all missed this while cursing a computer for not starting up), and could leave you with call-out charges and a red face.  Try another cable that you know to be functional, and try your cable in another computer.

I don't understand what you mean by 'recommendation'. But, I think you should split the points between us all - seeing as we tried but had no reply.

Sorry if I got this 'recommendation' thing wrong, I'm new to this.

Yes, you got the idea of Venabili's expression "recommendation", but I'm not sure you caught the drift of the fact that a comment should answer the problem (or provide enough information that would have allowed the user to begin fixing the problem) before it is worthy of acceptance or inclusion in a points split.

There are two comments to the question that MIGHT have pin-pointed the problem, and would serve as the very first steps on the way to diagnosing it.  jamietoner suggested that the Power Supply Unit was probably blown, and I suggested checking the mains supply fuse.

The question stated:
>>>
"I push the power button and nothing comes on.....I can only deduce that it might be the PSU........there isn't even the reserve power light on the MOBO".
Your comment was:
>>> "adjust the Power settings by Right-Clicking on the desktop....", etc, etc.

Clearly that wasn't an option, given the fact that the computer is dead, and it would seem that you hadn't read the question fully.  So unfortunately even if the points were split, your comment doesn't really justify inclusion in the points split whereas the comments by jamietoner and me possibly do.

I'll leave this to the moderators, but my suggestion is to delete the question with no refund of points unless crrp6501 returns with feedback or finalises this question personally.

Yes, you're right sorry. I still didn't read the question, just read the question properly and felt like an idiot. You're also right to post that comment, lol. Sorry for not reading it properly.

This is the second time this has happened to me :( Both in the Hardware TA... Might just stop visiting this topic.

Hey guys,

I'm really sorry for letting this hang.  I have not had my computer for the past 3 weeks; it went to the repair shop.

It was in fact a faulty power supply unit and it took awhile to get the part replaced.  After reading the latest responses I am indeed going to divvy up the points.

Jamie, you were pretty much on the money and Bill, I can't thank you enough for the 'Warranty Wisdom'.  Very helpful!


Thank you again,

Thank you, crrp6501.
Glad you got it sorted.

Nerdx, we've all done it before.  Occasionally, while thinking about a completely different question I have been reading, I post a suggestion that is completely alien to the one being asked.  Now THAT's where you end up feeling pretty idiotic :-)
