Unable to boot any OS

[Josh93210]

My situation is I was playing games and it crashed multiple times on restarts in game. Eventually my computer wouldn't get past the windows 7 logo. It wouldn't go into safe mode, with a usb with windows 7 on it I couldn't repair the windows 7 files and would basically say contact system administrator. At that point on boot up of my PC after the bios splash screen I would get random numbers, letters and triangle symbols. I tried reformatting the hard drive with windows 7 and that still didn't fix the issue where after the bios splash screen I would get the random letters and numbers and the PC would hang there. I tried reformatting to windows 10 x64 and It would let me log in because after you install windows 10 it doesn't make you restart your computer it logs you straight back in. After the restart of the PC because I was trying to install drivers I got the same issue, which was after the bios splash screen I would get random letters, numbers and triangle symbols and PC wouldn't boot windows 10 x64. PC boots usb sticks with OS's on them fine with no errors. Just when trying to load an actual OS on a hard drive after I reformatted and installed it messes up. I have 3 hard drives and after the splash screen they all get the random letters and numbers/freeze.

Thank you so much for any advice you can give for this headache. All components are approx 6 years old. I really don't know if it's my hard drive, video card or the bios.

It could be anything really, but I would start with the ram. Have you ran a memtest, and do you have any spare ram to replace your current ones? It might be just one stick of ram, so you could try to remove two and test it with only one module.

Checked it with each ram individually with same result. Took ram out and a screen popped up at start up saying it recognized less ram was installed and went right back to random letters and numbers with no boot. I reseated video card and cpu with no luck as well.

Would you happen to have a spare hard drive laying around? it could be a failing drive. six years is pretty old, especially for a hard drive, they only have so much read/write cycles before the drive will start to fail, and can cause many problems.

Yes, if the ram is good, check the harddrives. Usually on any manufacturers website you can download a hardrive test tool, burn it onto a cd or put it on a stick and boot the pc from it to test the harddrives.
