Help needed please for a frequently switching off Dell Studio

[aj4xxx]

Hi,

I have a Dell Studio 1558. It has been getting quite slow lately since it's been ages since I've formatted. So I decided to format it via USB. No sooner had I formatted my System drive and started installing Windows 7 (the Installing Windows option), the laptop switched off abruptly. Thinking it was just an accident I repeated the same process and in 5 minutes, it switched off again. Tried some times and it's the same problem. Took it to a laptop mech and he said it might be a heatsink problem so he fixed the heatsink, but the same thing happened again, albeit after ~10 mins.

So could anyone let me know what might be the issue? The lappy was fine till I formatted it and started installing Windows. It surely isn't a GFX problem since it doesn't have an OS yet. So is my motherboard conked or is it just a heatsink problem which wasn't fixed correctly? Surely installing the OS and this happening is a coincidence?

I also had a motherboard issue previously and got it fixed.

PS. The lappy is getting heated up pretty quickly, especially at the fan area, so I'm hoping it's just a heatsink problem.

Any input would be hugely appreciated. Thanks a lot.

Time for a new laptop, its not worth it to sink so much money into fixing old hardware and with time laptops go especially when theyve been through alot of heat and time.

Heat will absolutely shut it down. Make sure the fan is working properly, and that the heat sink is clean/free of dust.

I'm not sure what kind of work the tech did, but the heat sink may need new thermal compound.

Thanks for the input, both.

I'm a student so can't really afford to buy a good laptop right now. So I'm pinning on to the hope that it's a heat sink problem.

Is that a symptom for motherboard failure too?

Weird thing is, the laptop has run at pretty higher temperatures than the present and hasn't shut down by itself. Now all it needs is just a little to moderately high heat around the fan area and it goes off.

Shutdowns tend to occur based on one of two things: failing component(s) (or a component that isn't seated properly), or thermal threshold is reached - which also could allude to an improperly seated heat sink.

What are your temps at? I think most systems cold shutdown right around 100 C, and throttle CPU and GPU when the system reaches the 90s C.
