Hello! I have inherited my desktop computer from my previous work yesterday. It is a HP Z2 tower purchased March 2023. My previous company wiped all work related software and system in June 2026 since I was not allowed to leave the company with internal data. Since then it was not used but left on the desk.
I could only collect it yesterday. When I turn it on, the power light goes on, the fan is working it sounds like everything is fine but it is not detected by any monitor. The smart Samsung monitor provided with it says the message: Turn on the device connected to HDMI and just goes on standby mode after 1min. While my gaming OMEN monitor I plugged to it just remains black. The tower has been on for the past 15min. White light is flashing above the power button but no way to see what is going on or use it. Fan is blowing.
Any tips to make it work again will be much appreciated! Thank you!
