Hi, i post my question earlier in the hardware forums. They didn't help me out. Here is what happened:
-My USB ports were working inconsistently. Sometimes they would work immediately, sometimes they would work after 10 mins, sometimes they wouldn't work at all.
-I updated bios, OS and chipset drivers. I believe the problem is sometimes BIOS is not giving power to USB ports at startup. Strange thing is %80 of the time, when USB ports don't work, i shut down the pc. When i shut down the pc usb ports start working for 3 seconds (it charges my phone) then they stop. When i boot up my pc, it doesn't work. BUT when i shut down my pc and in those 3 secs (when ports charging my phone) if i boot my pc up, PORTS WORK! Please help me.
Solved! Go to Solution.

Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:
Let's try uninstalling USB Root Hubs and check. Uninstalling USB Root Hubs forces the system to reinstall the root hubs next time the computer is started.
Use the following steps to uninstall USB Root Hubs:
Disconnect all USB devices connected to the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
In Windows, search for and open Device Manager.
The Device Manager window opens.
Double-click Universal Serial Bus Controllers to expand the list.
Figure: Universal Serial Bus controllers list in the Device Manager window
Right-click the first USB Root Hub in the list, then select Uninstall.
Figure: Uninstall selection in the Device Manager window
Click OK to confirm.
Continue uninstalling all USB Root Hubs listed.
Close Device Manager and restart the computer.
If the USB device that is having problems came with software and it was not previously installed, install the software now, following the manufacturer instructions.
Reconnect the USB device that was having problems and test it to see if it works.
Hope this helps! Keep me posted for further assistance.

So, the problem was a manufacturing problem. I contacted HP and they gave me a service report. With that, I was able to replace it with a new one.
