Computer Shuts Off after 5 minutes
(Click here to view the original thread with full colors/images)
Posted by: rockshalton
Hey everyone,
I have a HP that shuts down after 5 minutes after I turn it on.
It takes about 30 minutes when I can press the start button to turn it back on.
This happens everytime I turn it on.
Whats wrong?
The power supply and cpu fans are turning and seem to be ok.
Please help me out.

i would guess its a cooling problem. whether its the power supply or cpu is the question.

RED!
Hi!
I thought about the power supply but it sounds good (not making that usual loud cranky noise)
Before I spend th $60 bucks, is there anything I can do to better evaluate the problem.
Thanks so much for responding.
I alaways like reading your posts / replies.

well, you can (hopefully) at least monitor the cpu temperature, and eliminate that as the problem. the motherboard manufacturer should have a temp monitor for download.
sandra might be able to spot the problem, if you can keep it running long enough. clean off the outside of the power supply, and open the case and turn a fan on it. might not help, but who knows.

Thanks Red!
I like the fan idea.
At this point, do you think I could rule out some type of a virus?

I dont think a virus can stop you from turning it back on for a period of time. Heat/cooling would sound like the logical explanation like redwench said. Open the side pannel, a bit for better circulation, and if you can put the fan on it

Thanks Z!
Im glad to hear you dont think it's a virus problem.
This thing was possed for a period of time, plagued with the buggers.
I think i eliminated all the viruses.
As far as the overheating, everything is clean as a whistle. I know that probably doesn't matter with my situation.
If the fan thing doesn't work, what would you and or Red suggest further.
Thanks

How long have you been using the machine and when did the problems start?
Seems like you have been using this for a while.
If you have had loads of virusses I would also suggest formatting your hdd at some stage if you can. If it isnt the power supply overheating I would guess it could be the CPU , clean the heatsink and see if it has some heatpaste on the cpu itself.

Thanks again Z!
I am not familiar with a heatsink!
Please explain further.
Thank you

if the heatsink fan died, thats easily replaced. if one of the fans on the power supply is gone, youll pretty much have to replace the whole unit. assuming its not something else, of course.
Posted by: zorg
oh dear, I wouldnt suggest fiddling with the heatsink and fan unless you know hat you are doing or wiling to learn through potential mistakes 
When you open the side of the case, you should see a biggish fan on the motherboard itself attached to a bigish piece of metal, this is cut into thin slates so as to disapate the heat from the cpu, the fan blows over it to cool it down. Considering that you probably havent looked at this before make sure the fan isnt dirty and can turn easily, dirt and dust can be a killer to fans.
BUT be carefull if you are unsure about what you are doing rather get someone to do it for you, just make sure that the fan is clean. I usually do a bit of a hack job by using a footpump with a nozzle to blow all the dust out of my heatsink and my case in general.

I once had a problem similar to this one. My problem was that a heatsink on the board itself popped loose. Not sure what the heatsink was for though, this was a computer or 2 ago. This may or may not be your problem but it wouldn't hurt to check anyway.

Thank You!
I Hope To Corresspond With Both Of You Again.
I Have A Better Starting Point Because Of Both Of You.

Hey Again,
I tried running a fan on the inside of the computer but it still shuts down after 5 minutes.
I checked for any loose parts including everything surrounding the cpu.
The cpu fan is running fine and the temp is 51 cel.
What can I do next barring buying another power supply.
Posted by: RAcastClarke
51 seems really high...
Posted by: redwench
not for a pentium, its not. they arent temp sensitive, and will underclock. unless thats just the temp at boot.
try sandra, see if it puts up any flags.
Posted by: RAcastClarke
Sorry, I had assumed that normal running temperature was around 35 C or so..
Guess I was wrong.
Posted by: redwench
pfft. my p3 hits the 80s on a regular basis, without underclocking. 51 is perfectly acceptable even for an athlon, although it would then definitely need close watching.
Posted by: RAcastClarke
Wow.
I'm retarded, hah.
Wonder what mine runs at..
It's only a PII 350 though..

Im unsure how reliable this tab is, but my XP chip runs more or less in the regions this list is on about.
Posted by: rockshalton
Hey,
I really appreciate the continued support.
RED,
Sandra?
What's that missy?
Posted by: rockshalton
Z,
I found the 51 c acceptable through docs and boot.
Keep 'em coming though. You too, my sweet RED.

Rock, do you possibly have any access to another machine with a powersupply even if it is a bit older as long as it supports your motherboard, just to test the powersupplies, changing them isn't so big a deal. Have you had a close look and listen to your powersupply when you switch your pc on? If you cant hear a fan in there you might be in trouble, need to get a new PSU then.
Posted by: rockshalton
Z,
I do but unfortunatley the one in the older modle isn't atx and only 200w
This one is atx 300w.

Of course there is always the "finger" test, be careful though you can burn yourself. If any of the products inside your case gets so hot you cannot keep your finger on it for a couple of seconds that means its overheating. when you burn your finger, its too hot and you need to try and get some extra cooling on it. Of course as you can understand this is not an exact science  but it might just give you some better insight into what might be overheating. I think red's initial thought on the powersupply might be your culprit, just feel the underside of it with your hand while the pc is running. Once again please use caution, I have no idea how warm it might be
Posted by: zorg
Thats a shame, try to see if you cant get an old machine off of someone with a workign PSU.
Posted by: rockshalton
Z,
Yes, one of the first things i did was to do the finger test.
everything feeling ok but the pride.
I have the $, but can't resist the challenge as i do not think its the ps.
I respect and am grateful for your persistance in trying in helping me out.
my gut is saying there is some little thing wrong here but, you know, with all these tiny little parts, it could be anything.
i will stay at it for as long as my patience holds out.
i'm sure you know how that goes.

HAHA you have no idea, I have had 3 hdd's crash on me in the last month, well only really 2 but a 3rd spare one as well. My cousin's 40 crashed and trying to get the data off of there was absolute hell. My 60 is acting up and I cant write to it, it seems to read fine, but wont write and I cannot instal windows on it as it wont allow the xp cd to boot up :P O well , the challenges pc's bring... Just like woman only difference is they beep at you, and then gives you the silent treatment, woman... well... you get shouted at first :P
Posted by: zorg
Sorry rock , but i was just thinking, you said that the pc shuts down after 5 mins, and then wont allow you to boot up again within 30 mins. Does this mean that no power flows through, or the pc just doesnt Boot up for 30 mins ie the fans go on, but no bios/windows boot screen?
Posted by: rockshalton
HA HA HA Back!
Yes, and how i love the women in my life.
YES!
if they could only beep instead of shouting.
maybe part of my unfocused & impatient behavior of late!
You seem a good type and I thank you for that.
My girls have become jealous of the time i spend on this stuff.
Do you know how that is?
I become obsessed with things, especially the pc.
If only i can fix mine like i fix others.

you can always tie a string or 2 to the exhaust of the power supply and see if the airflow is normal.
