Hi,  I was just wondering if anyone could give me any advice on whether I should purchase a new processor.  
 
The reason being, I had a problem with my PSU, it wasn't supplying power to one or a number of components.  I had to send it back to the manufacturer to be replaced as it was still under warranty.  When installing the replacement PSU, I had to remove the processor cooling fan in order to get it in.  Unfortunately I made the mistake of putting the cooling fan back in the wrong way round, it was blowing outwards rather than inwards.
 
I was playing a rather demanding PC game on my system (Civilization 5) whilst the fan was on the wrong way round for a number of hours.  The game now causes the whole PC to completely shut down instantly after 10 mins to an hour (it cuts out, like a short circuit or a failsafe) even though the fan is now installed correctly.  If I try to turn the PC on again immediately, it starts up but the fan just whirrs around and the system does not start up.  I remove the power cord from the back and leave it a few minutes and it starts up again.  The PC experiences no problems with other tasks such as browsing, videos, word processing etc.  I never had any problem running this game before I had to replace the PSU and I made the mistake with the fan.
 
Therefore, I wanted to know if anyone can advise me whether it could be due to the processor being damaged?  Or is my cooling system faulty? (The fan seems to work ok)  Should I buy a new processor or a new fan or could it be the motherboard?  I don't want to buy a new one if it isn't going to rectify the problem.
 
I'm really stumped.  I've tried reconnecting all the components to the new PSU, cleaning out the inside of the case, moving the base unit to a cooler place, I even leave the side off the base unit to aid cooling.
 
Any help or advice would really be appreciated, thank you.

This sounds like thermal shut down - a power supply safety feature. One cheap thing you could try before you consider any more expensive solutions.

 

Is there any possibility you disturbed / moved the heat sink when you took the fan off ?  Get hold of a tube of heatsink compound. Remove the fan and the heatsink from the CPU mount - it's not necessary to remove the CPU - and clean the mating faces of the heatsink and the CPU. Then apply a light smear of the compound to one of the two faces - ie either the top of the CPU or the bottom of the heatsink, and then replace the fan and heatsink. You don't need anything special to clean the faces, I normally use either a paper handkerchief or a clean bit of rag. Just don't get it on your clothes, it takes forever to wash out !

 

If you don't have any heatsink compound to hand you can get it in any electronics store or on-line from any number of suppliers - just google 'heat sink compound'.

Mr Cosgrove is right, though I would advise that you put the heat sink compund on the surface of the processor rather than the heat sink, and spread it carefully so as to get a perfectly smooth thin layer covering the entire square flat upper contact surface of the processor before you reinstall the heat sink. Finally I would recommend "Arctic Silver 5" as being the best heat sink compound to use.

Hi.

No I do not believe You damaged Your processor.

The computer is designed to shut down before the CPU temperature gets hot enough to damage the CPU.

I believe that if it was damaged it would not be working.

 

If You buy arctic silver thermal compound, their website has tutorials on how to properly apply the thermal compound..

 

One other thought, Do not use your finger to smear the thermal compound around.

Use Isopropyl alcohol to clean both surfaces, Lint free cloth

 

Good Luck

Roger

Thanks very much for everybodies help on this. I have ordered the Arctic 5 thermal compound. I'll apply it and let you know the results. It'll take a couple of days for it to get to me. I'll let you all know if it works. Im wondering if the original paste my have melted off then or maybe I cleaned it off?

Well if you remove the Heat sink from the processor, that wrecks the thermal componds heat transfer abilities, because the compound drys to some extent after the heat sink is applied, and if you remove and reinstall the heat sink, the heat tranfer capability is considerably reduced, unless you clean off the old heat sink compound, then apply fresh compound before you reinstall the heat sink.

Hi everyone,

 

Unfortunately I'm still experiencing the same problem.  The CPU doesn't seem to be getting as hot now I've applied the Arctic Silver 5 but my computer seems to shut down if I play Civilization and occasionally if i leave it on for a little while.  

 

I have to leave it for a few minutes and turn off the power at the PSU before it will turn back on again.  I'm really not sure what it could be.  Any suggestions?

Also I applied it exactly as it said to do. I have another problem now tjough because my PC fails to start up if I shut it down. I usually have ro turn it off and on a few times before it even starts up. What could this be? Is something damaged? I don't really know where to start tbh. Thanks.

Hi, How old is this computer? The not turning on properly does sound like a hardware problem.

 

Can You post a sharp image of the motherboard as it is in the case?

 

Thanks

Roger

Another issue is : Is your heatsink clean ? i.e. completely dust free ?

It could be that the fins on the heatsink (if it has any) may be bent and may reduce the thermal transfer. Is your fan spinning at all? If it isn't it could overheat the processor by not transferring the heat out of the case.
