"Hi @kaito32 ,

What is the make and model number of the computer or the motherboard if a custom build?

If it boots OK from a USB but not from the HDD it appears to be a HDD problem.

Try getting into BIOS on startup and check that you can access all menus etc just to see what happens.

Getting the logo screen indicates that the hardware is mostly OK as the PC has passed POST (Power On Self Test) but the glitches etc is when the HDD is loading the OS and that is where the problem is. Corrupted HDD, faulty HDD etc.

Has the BIOS got a diagnostics program or perhaps the computer maker might have one online so that you can test the HDD. You could always try reseating the cable connections to the HDD at both ends in case one is loose etc. Alternatively try another HDD and install an OS on it."
