We're going to need a bit more information from you. Have a read through the thread above and get back to us.
I can be talking about golden rabbits wearing bow ties and three minutes later I can an advert about buying one.
You’ll never convince me that our phones don’t affect that. Just wish they’d use it for some good instead.
Outside the obvious CPU issue, I would have gone for a better cooler with that chip, but the honest answer is that it probably wouldn’t have mattered anyway. The chips are broken and not fit for purpose. It doesn’t matter how many times you change it.
We ask for the full specs to ensure that the laptop isn’t stolen and was ordered from PCS.
If you bough the laptop from someone you know, it’ll be easy to either transfer the warranty or get them to login from their account to get the information needed for you.
Putting that GPU in that build is like putting the engine of an Aston Martin in a Fiat Punto.
The GPU costs more than the entire build. Is there any reason why? Is it just a budget issue?
When it boots up “for a second”, does it post? How many, if any, beeps do you hear?
When it’s on for five minutes and turns off, do you get any error messages or does it immediately power down without warning?
Before it happened the first time, did you recently download/update anything...
In that case, like you’ve already been advised, I would sell your current PC and put that money with the £1,400 it would cost to upgrade this one and get a completely new build. You’ll find you get much more for your money.
