I bought a second hand HP Z400, using it whit Asus 560 GTX graphics card. (But tried to solve the problem with the oem nVidia 3700 and nVidia 730GT)
A week ago it started randomly restarts (without any blue death or something, like when you push the restart button).
Now it is unable to start because it wont reach the windows loading screen. Before that it restarts.
Is it a known problem?
I tried to update the BIOS but when I opened the bios and tried to find the bius update it restarted itself again...
Hard to understand that. Is it a PSU issue? Or?
Thank you for your answer.
