So I purchased a used gaming pc. With ecs mother board Pentium 4 core 3.50 ghz. 550w power supply Hitachi hard drive. (Not ssd) and radeon stu graphics card. I had to purchase a hdd. Now when it boots. I get 2 beeps on boot then goes to auto recovery. I think its windows 10. I tried booting from usb drive just sits on windows logo. Or if I do the recovery it just reloads the recovery page in under a second. Tells me win38.exe failed to start error code. I used to be techy but now I'm old I guess. (I can not acces bios. Just 2005 cmos screen. Or boot selector) I tried pulling all 3rd party tech out same boot. Nothing works. Do i need to wipe the mother board before trying to re install windows? If so how do i do that??? I did cmos jumper. It wont start unless jumper is on left 2 of 3 pins. I'm so confused!!!!!!
