Any pc techs out there? I need advice.

[The Nameless]

I'm looking for some advice from Brady hartsfield types. My laptop was overheating, I put a hardware monitor software on it and it turns out the processor was running at an average of about 70 C and would turn off when it reached about 90 C. So i replaced the old thermal compound on the processor for thermal silicone pads but it got worse, so I replaced them with new paste and it died.

Where as a working laptop would blow the fan strong for a second or 2 when switched on, then the fan would die down and it would boot up, mine blows the fan constantly with no boot up, no post, nothing. No beeps or other noises. I've tried it on just battery, just power cable, and both. The fan is spotless, no bent blades.

My main question is, motherboard or processor? The motherboard looks OK at a glance, no bulged or blown capacitors.

Any ideas?

I'm not a tech, but that experience sounds similar to one we had with our old laptop.
If you're not getting the BIOS/UEFI screen popping up, it could be your motherboard or your GPU is fried. It could also have been that it was the GPU that was causing the overheating. If it got too hot in there and the fans couldn't cope, it would cause the whole thing to get too warm and the processor would give a high temp reading (for obvious reasons).

In our case it turned out that the excess heat had damaged the motherboard too badly. I've also had a desktop PC motherboard fail without there being any obvious signs of damage in the past, so it's not always obvious.

If you happen to have a spare laptop GPU lying around that would fit, or a second laptop that you could 'borrow' the GPU from just to run a quick test, do that and see if the BIOS/UEFI screen pops up and it boots Windows.
If you can do that and everything appears, there's your problem and you need a new GPU (you might need to fork out for other upgrades though, e.g. to the fan). If it's still blank, it could be a motherboard issue and something has burnt out that you're not seeing (though then I think the whole thing should fail, maybe) or the high temps, etc, have killed the processor. Either of those won't be cheap and you might be better off getting a new machine (you definitely will be if it's killed both processor and mobo, unless you know of a place you can get a decent cheap bundle from).

The only thing I can say if the GPU thing doesn't work is to take it to a reputable repair shop or, failing that, somewhere like PC World if it's your only option, and let them take a look.

Did you try getting out and then getting back in?

My GPU is built into my cpu


I've looked them on eBay and used and tested working ones are only a few pounds, and there are plenty of them. If it's the motherboard though, they just seem to have stopped existing. I've found them for many other laptops of the same make but not my particular model.

I've had every part out that is not soldered in place and put it all back together.

Once you go Mac you'll never go back!

No viruses, software crashes, or fried components in the 8 yrs. I've had my iMac.

agree!

Have to concur with swiftdog2.0 and DJ. I got a Mac mini to avoid the horror show that is WinBorg10 and to prolong the life of my increasingly creaky PC (for gaming). When the PC finally dies it will not be replaced (though I'll probably have to get a Steam machine to access games...unless I just decide to walk away. I've already had my money's worth out of most of them).
Mac all the way from now on for me. Plus it's guaranteed for umpteen years (10, IIRC), so the extra cost pays for itself seeing as I'd probably get through (at least) two PCs in that time.
Fewer cables, takes up much less space. What's not to like?

10 years on a macbook. Held together with packing tape, but still going.
