help please my pc shuts off and wont re-start?
I’ve had a pig of a day. My PC without waring shuts off. Just dies and won’t restart. I’ve managed to get it going again by taking out the battery, resetting the CMOS, reconnecting the battery and then …. hey presto, it’s boots up. BUT …. not for long, then it goes off again.
Anyone got any ideas as to what the problem might be?
I’m tearing my hair out!….. this is the 4th time I’ve tried to post this! 👿

First thing I’d check is the processor fan. If it overheats most systems are programmed to do am emergency shut-down.
Open the case when powered up & see if it’s running.

Fans are all running David, that was my first suspicion. In fact I’ve kept the side off the computer to see if it makes any difference. I’ve been up and running again now for 15 mins … that’s good going at the minute 😕
-
Hmmmm. I’d stick with the temp thing just now. If you go into the BIOS at POST (F2, F10, Del) ie. whatever it takes and check the processor current temp & shut down temp. Also, if it’s possible set for ‘fail safe defaults’ instead of ‘performance’ as if the processor is overclocked it’ll overheat.
ps. What kind of shut down is it.
Emergency 3 seconds & off, or normal shut down sequence?
-
eh …. immediate shut down no warning whatsoever. Black screen and dead immediately.
-
Did you manage to check the temp & settings? Although resetting the bios should have restored factory ‘safe’ defaults.
eg. If the core temp idle is 70c (high) and it shuts down at 75c – it’s begging for a shut down.
Have you tried ‘percussive maintenance’ yet? 😛
-
A huge % of PC problems are heat related Marcela.
Even if the fans are spinning, the contact between the CPU and the heatsink may not be sufficient enough to disperse the heat properly.
This is caused by inferior thermal paste being used on cheaper pc systems.
If your probelms persist, it`s worthing looking at.

Disconect power cord, remove RAM, conect power and try to power on computer if there is beeps – you must change you RAM. If you don’t listen any beeps – plug RAM back, then remove video card and all other cards /lan, sound, etc./ that you can remove /with power cord disconected, remember this/ and try again. If you listen beeps, some extension card is dead, if you don’t…possible processor or motherboard failure.
-
I removed the ram 2nd time it chucked it. But that didn’t help either. It’s been fine now for must be 30 – 40 mins now. I’ll wait a while then check the temp.

what’s that? 😮 🙄

What make is it as this’ll help narrow down things a bit.
ps. Some systems will beep regardless if you alter any of the internal components, eg. Compaq. It’s a simple security measure so you can accept the changes manually.
Beep tests are specific to each Bios manufacturer, and will only indicate massive component failure or conflicts.
As your system is running for some time, it MAY be the memory (one duff chip or bank). If you have two DIMMs, try them independantly – if only one, try re-seating it. I really don’t suspect a duff module, but it’s not unknown for it to cause (more frequently) lock-ups…never saw it cause shutdowns though.
EDITED TO ADD: OK, you’ve already done that whilst I was typin’!!

It’s an Asrock motherboard, AMD 3.2+, running 1064m ram. Never had any problems at all until today.
-
I’m still erring toward heat. That AMD will be running at about 3.0 Ghz, and if it’s been a ‘custom’ built one, it’s not unknown for some shops to skimp on the cooling fan & heatsink.
I run a similar setup at home (only 2.8Ghz AMD) and it NEEDS a flippin’ huge copper ‘sink, hi-flow fan & two case fans to run at optimim speed.
I’m strongly suspecting overheating (as you can tell), as a few months back I accidently blocked the case air inlet & it kept doing the whole crash/die thing on me.
Would be interesting to know the temps though.
-
I have one Asrock that ‘die’ before 2-3 weeks. It just stop working in the middle of the job. It starts one or two times after this stop and then stops working forever. But it is with Intel chipset, probably you have different problem, defective module or like other says – overheating. If it stop again, try to reset all power connectors inside the PC. Just remove and plug again.
-
Could be the PSU on the way out?
-
…any good news? … 🙁
I think i’ll buy a new GIANT fan … perhaps it’s the baring in the heatsink that slowing down…….
-
first thing went into my mind is HEAT and air flow…
Faulty PSU… weak PSU…
dust… heat… fans stuck… um
that sort of thing like the others have said -
Just had my tea. Mmmm.
As a rough guide – if it’s running at over 60 Celcius, it’s getting a bit warm, 85 degrees is often the default shutdown.
Certainly, if it’s over 65 degrees at idle (just bios on screen), then a replacement heatsink/fan combo could be in order. You can reduce the CPU temp by maybe 2 or 3 degrees with an additional standard case fan.
Make sure your fans blow down onto the CPU or into the case, it’s more efficient when cooling to bring in cold air than try to extract warm air.
Something like this for the processor.

It’s bad news I’m afraid Marcella 😕
The symptoms you have described match up exactly with the theoretical symptoms that a PC would exhibit should it ever contract a case of Avain Flu
I believe your PC is the first recorded incident of Avian Flu to cross over the organic/Machine threshhold.
This is a realisation of our scientists worst fears. Bird flu as we all know is very difficult to catch but the fear was that a mutation of this virus would not only cross the inter species divide but make a further leap across the organic/Inorganic divide…… In other words, your PC has got Bird flu.
This is an absolute disaster for mankind as we all already know how fast viruses spread across the internet. It is essential that you disconnect youre PC from the interent now … not later… Now Marcella.
Even as you are reading this your PC could already be infecting millions of other PCs over the internet.
We’re all doomed…..

Yeh, I run at about 43 C. The figure of 60/65 are the threshold level for an idle temp for the "It’s gonna die – just a matter of time" scenario when you actually start doing anything requiring processor time.
Was a note that if close to this at idle – definate heat problem requiring much better cooling, not suggesting as a normal idle temp!! -
Who cares – we’re all, doomed …… Is no one listening to me (hot)

Has your PC ever been thermostatically modified to cope with the tropical climate in Scotland?

Have you found the fault yet !!!
AMD 3.2 CPU usually overheat alot, try a new CPU fan about £10 from a computer fair
it has to be the big and I mean BIG Heat transfer Fan
How long have you had it ?
Try that first, it will only cost you £10
Ken

Phill – you’re mental :tongue:
Dawn – you’re as bad ….. tropical heat? No … but’s waterproofed! 😀
It’s only 7 months old …… I’m going to get a great big fan and blast the damned thing until it’s frozen!!!! :lol1:

Don’t just get the fan – get a nice big heatsink as well suitable for an AMD ‘3500’ and above.
If you’re fitting it yourself, the removal of the old ‘lump’ must be done with a lot of care (fitting is easier), pushing down the spring clips that hold the ‘fan/sink’ down required patience & a steady hand.
On the bottom of the new one – there will most lilely be a small square patch of thermal paste under a clear sticker – it’s adequate for most purposes, or buy the smallest tube of good thermal paste (silver) for a couple of quid & add a little blob dead centre.
ps. You don’t need to remove the processor from its socket to do any of this. But you might need to pull out the drive power cables as access can be a little tight in some machines. Anyway – it’s well within your abilities to change it over. (I don’t want to sound like I’m saying what you already know 😕 )

I had a prob with my 3.4 shutting down and crashing
Due to dust clogging up the fan. Took it off cleaned it and no probs since (It was dirty)
Fan and heat sink looks like it was made by rolls royce or some other airline manufacturer its huuuugggeeeeGoop
-
eeeeeh… Lets se if I can find the tecnical word for a reply.
It could be problem with the main power-dingy (transformator)
There are a small thermostat in bimetall in it that shuts off the power when it gets to hot.It whill let you start when it has cooled off.
Sometimes it requeire that you disconnect the powercordEven if the fans on Cpu and graphiccard is running they can run to slow.
An AMD cpu can run wit no problems up to about 60-65 degrees C -
Update: I bought a new heatsink today and so far …… all is well. 😛 Let’s hope it continues!!!!
-
Good luck with the new heatsink!
Watercooling is the way forward! True SILENT operation, and my CPU clocks a steady 19 degrees 🙂 Sometimes peaks over 22 under heavy work (Couter-Strike) :lol1:
-
watercooled….. very fancy! Bet that’s expensive!
The heatsink is working fine. I’ve had no crashes since I put it in on Saturday….. thank god!
-
…and long may it continue.
-
quote Marcella:watercooled….. very fancy! Bet that’s expensive!
Not really. A decent 100% copper heatsink will cost about £60 ish, and this water cooling kit, including, the CPU cooler, pump, radiator, g.card cooler panel, and coolant was only £110 🙂
