Overheating Issues? - In need of SERIOUS help!

[Howarth18]

Okay, to keep it as brief as possible. I have a 2 year old Samsung laptop that has is medium/top of the range. I have never had one single problem with it and took good care of it.
One night something was spilled on it and the motherboard fried. I sent it off for repairs, and when it came back it returned with overheating issues. the sound would distort, everything would jerk and boom - off it went.
I returned it yet again for repairs, in which they replaced the cooling system and the fans. This, however, solved nothing and the overheating issues reoccured during playing games such as Warcraft 3, games my laptop has run swimmingly for years.
So as you can imagine, i'm getting rather naffed now as my laptop keeps being returned to me with this reoccuring problems.
I return it AGAIN, this time it's given a full valet, stress tests ect. and the repairmen come to the conclusion that the laptop is completely fine - which baffles me but hey! why not. After a complete system restore my laptop is returned to me in the condition it's in now.
for roughly 2 days everything worked fine. Then it suddenly overheated today. I placed it onto a table, plugged it in and continued playing and it worked fine the rest of the day.

Now brings us to the current hour. The minute my laptop is turned on the fans sound like jet engines, they don't stop and 20 - 60 minutes into usage - pop - shuts down with no warning what so ever. this is after the THIRD REPAIR. and this is why i'm doing nothing other than browsing on the internet

please. HELP.

You can run software to tell us what is already suspected, but more specifically which component is overheating. It's probably the GPU, in which case simply adding a small copper shim on top of the chip to improve heat dissipation cures the problem, but you would need a reasonable level of expertise to achieve this. A Service Manual and some basic tools are required, there may even be Youtube videos for your model, the Stickies at the top of this forum would help.
Meanwhile Speccy should list all your Temps

If not, GPU-Z should check your GPU

If you decide to try yourself, pay particular attention to the application of thermal paste, it's at the heart of good heat transmission, again good Youtube videos on the subject

Okay well I downloaded the software you recommended and it was showing temperatures at an average of 60 degrees, never going above 70 which I believe for my laptop model is normal. I then put on Football Manager 2013 and during the non-loading/generating screens the temperature is again between 60 and 70 degrees - however whilst the game is in loading/generating stages the temperatures hit highs of around 90.



Now, by the red - I'm guessing those temperatures aren't good at all. They stay that high for a couple of seconds.

When the original incident occurred, was the Motherboard renewed? Whatever, it's getting way too warm and shutting down. Which components are reaching 90 degrees? Would you be prepared to attempt to sort it yourself? I take it the warranty has expired, though it probably wouldn't cover liquid damage...If you decide to DIY you'll get plenty assistance.

The CPU was reaching 92 and the Motherboard was reaching 82.

In recent weeks I've had the Motherboard and the cooling system/fan replaced as well as a full valet and still the problem persists. For two years I've had no problems what so ever with the laptop no matter what I was doing with it / playing on, it's only AFTER the motherboard was replaced that I've had these overheating issues.

I'm fully prepared to have a go at fixing the problem my self as long as there isn't a risk of causing more damage than there already is.

I would take the laptop apart and add thermal paste the the CPU/GPU if there isn't any. I kind of suspect theres not any applied considering I have had that happen to my laptop before after getting it back from dell. Or they could have just seated the heatsinks wrong. You can pick up a cleaning agent to clean off any old thermal paste for a few dollars and good thermal paste for another couple bucks.

1) Remove old thermal paste if there is any.
2) Apply new thermal paste.
3) Clean out dust with compress air if there is any.

Only do this if you trust your ability to do so, cpu running at 92 celsius is hot, that is what is overheating. And when reseating the heatsinks go fasten it down from corner to corner diagonally so it gets seated properly (same concept as putting on a car tire).

You're more likely to cause damage by not doing anything! Tell us more, Laptop Model/ serial number etc., and that way we'll hunt out a Service manual if provided. Not stripped a Samsung yet, which tells me they are normally reliable... Start gathering tools. You'll need P1 and P2 Philips screwdrivers, and a means of prising apart the top and base sections. (I use one of the old fashioned, flexible, flat bladed kitchen knives, but some use old credit cards).Ideally purchase a wrist earthing strap, especially if working in a room with man-made fibre carpets. Keep the screws separate for each stage of the disassembly by placing in small containers. Egg cups, shot glasses, small poly bags, cups.... Keep them in sequence.. For Thermal Paste, Arctic Silver 5 is recommended, you can get it with a cleaning kit comprising two cleaning fluids and a syringe for application. Main areas for concern are separating the various types of connectors, they can be damaged if handled with force/incorrectly.Depending on what you find, you may need copper shims to improve your cooling arrangements, though if it behaved well prior to the incident I would doubt that.
