    • Poor quality
Size: 12GB RAM | 1TB Storage
This PC is noisy, poor quality PC compared to its price. Even my old refurbished dell pc runs faster and much quieter. The initial setup process was also frustrating - I have advanced knowledge and skills with desktop PCs especially with HP brand. At one point, while browsing the internet, the web pages suddenly went blank - pure white with nowhere to go, no clickable exit from the website, which could have been from the browser. But the main issue was from within this computer since I could not find any running activity within the Taskbar to end it (ctrt+alt+delete). The start button disappeared; there was NO way you can click the power button to shutdown or restart. I had t force shutdown. I never have had this experience since my computer life. Luckily, I have my Amazon prime membership which I can return it with a full refund. On a different subject, if you love your independence and your freedom with what you own, and you have paid fully to possess your computer, MS will not let you have it. When you get a new PC with windows 11, you cannot bypass MS email account. You MUST create an account before you can use your computer which you have bought it for you - it is your own computer now. but, MS still OWNS it. You are not allowed to download and install Google Chrome, for example, without first creating MS account and then they will let you free, or what they call it ' Switch out the S mode' (absurd) and then you have the right to download and install other applications as well. ... show more
