Warranty issues

[StonyDrugCnslr]

I am having a continuous issue with my desktop booting sequence as it never boots. I get beep codes which I have identified that it is my gpu to which I have reseated it twice(in total) - once to which I got the same beep codes upon attempting to boot to which I repeated it again to ensure I did it correctly. I have tried to contact support to utilize my warranty to which HP now shows it is not under warranty which doesn't make sense as I purchased a multi year extended warranty and registered my product with them and activated my warranty, but because they show that I do not have a warranty I cannot even get someone on the phone to talk to them and keep getting routed and rerouted again and again to "HP virtual assistant" it is like a terrible twilight zone episode. Extremely frustrating any advice, insight, or help would be gratefully appreciated.

hi

what is the frequency, series of beeps?

for the warranty, if extended, check your contract, which offer you have subscribed to..
I know it's sometimes quite special, because it takes into account the date of purchase, of the computer..
I don't think that has changed, but if you have, for example, an extended warranty, two years
depending on the date of purchase, the computer, and the date of purchase, the warranty, it may sometimes be that the extension is only one year
