PC won't turn on, CPU dead?

hi Fab8637

HP Envy I7 ==>> laptop

(I retrieved the data via USB adapter) = with another PC? (Link USB cable)

if the processor overheated to + 110°C = the cooling was blocked

it’s a feasible solution for the processor

if it had been the motherboard, you wouldn't have been able to recover your data

see you later

Good evening Bison Boiteu,

It's a tower (for family use), I think I'm going to buy a used I5 processor to give it a try, it’s not my main computer, but I would like to put my backup drives in it. The USB port on my laptop is starting to suffer from the backup operations. And if it's the motherboard, too bad for the expense.

Thank you for your response

Thank you for all this information, I should have mentioned it's an I7 4790 with an LGA 1150, it's starting to get old! Just like my laptop. That's why I think I can find a used processor at a low price. For my usage, it's perfect; I don't need high speeds. If that's the cause...

On top of that, I'm in the process of building another PC with an I5 13500 and MSI Z790 Tomahawk. I've done quite a bit of research to get here, still need to choose an SSD, RAM, and GPU. MSI RX6650 XT Mech. I want to clarify that I'm not a gamer, but I do photo/video editing and programming with 2 screens + 1 later.

I'm sorry again for my omission, and thank you for the links and research. I will update you on the progress. See you!

Even second-hand, an I7 4790 is likely to cost you a lot.

For your next setup, is it an MSI MAG Z790 TOMAHAWK WIFI or an MSI MAG Z790 TOMAHAWK WIFI DDR4 as the motherboard?

Indeed, if you're not gaming, a RX 6650 will be sufficient.

Hello

An Intel processor overheating?

Yes, due to a voltage defect in overclocking. Yes, due to a direct short circuit from the power supply. Otherwise...

The protections present on these processors, even this one which is quite old, are such that it's almost impossible to damage it from simple overheating.

I would look elsewhere before blaming the CPU.

Hello,

I'm considering replacing it with an i5 for testing (~€30 on Ali-Express)

I'm also thinking that there are overheating safeguards, but it was completely clogged and given the ambient temperatures... like what, having the PCs placed directly on the floor under the desk is a great vacuum cleaner.

As for the Z790, it's DDR5, I know it's going to be beyond my needs, but RAM has become affordable, plus I'm not the type to change often, so I might as well treat myself! Overall, it's a good mid-range setup, right?

Now I just have to handle the installation... My last assembled PC was over 20 years ago, I've followed the evolutions, I'm optimistic!

Thanks for the feedback

"I'm also thinking that there are overheating protections, but in this case, it was completely clogged, and given the ambient temperatures... it just goes to show that CPUs placed directly on the floor under the desk are like a super vacuum cleaner."

As has been said for a long time, CPUs have a protection system that takes them offline when there is overheating. So when a functioning PC breaks down, it's unlikely that the CPU is the cause.

Indeed, when possible, it would be better to switch to DDR5 since in the not-too-distant future, there will be no motherboards supporting DDR4. For DDR5, it would be best to choose modules with a minimum frequency of 5200MHz.

Hello,

The tests with the I5 are inconclusive, so I'm closing the box for now and this post. Thank you again for your participation in my quest to revive this PC.
