HP India — hp laptop issue

Address:

New Delhi, Delhi, 110018

I have opened many tickets in HP contact center here's the recent one
[protected]. Since the time I bought this laptop I had issues from day one.
So this laptop is Serial Number:CND7077MS5 with extended RAM of 8 GB which makes it my laptop of 16 GB. I extended this due to study as I need to create Virtual machine and which was the only purpose for me to buy laptop.
Everytime I use the machine everytime it boots up and I open nothing but task manager and always found 100%disk and 100% CPU this is when no application is running. How in the world I can work on this machine even though I managed to pull it off for almost 1.5 years but not now.

since Jan I'm opening service requests and try to isolate the issue everytime HP person tells me that it is windows issue and I need to re-install it, okay I did it not one or twice 4 times and still the same issue.

opened a new ticket, now they tells me to diagnose using there tools by F2 and surprisingly the hardware tests passed I don't understand why still I told them to send someone to look at the PC as this is not a normal behaviour of an 16 GB laptop to not able to perform simple tasks as it hangs very frequently.

If any one can provide me email address or any contact number it would be highly appreciable.
