As suggested, confirm the CPU is 64‑bit capable, and as noted, moving from a 32‑bit Windows install to 64‑bit is not an in‑place "upgrade" but a clean install. Below is a compact, practical checklist plus targeted fixes for the blank USB‑boot symptom.

Checklist (do these before attempting install)

  • Backup all personal files and any program license keys (a clean install will remove programs).
  • Confirm CPU capability: run wmic cpu get Name,DataWidth or open msinfo32 and check the Processor name (System Type in msinfo32 reflects the OS, not the CPU on a 32‑bit install).
  • Gather the exact Windows 7 x64 ISO for the same edition (Home/Pro) and have the product key ready.
  • Collect 64‑bit drivers for motherboard, chipset, LAN, storage and GPU if available.

Troubleshooting a blank screen when booting USB

  • Most common causes are a non‑bootable USB or BIOS/UEFI mismatches. Recreate the USB with a reliable tool (select MBR for legacy BIOS/CSM or GPT+FAT32 for pure UEFI systems).
  • Try a different USB stick and use a rear USB 2.0 port (older systems often fail on front-panel or USB 3.0 ports).
  • Use the motherboard’s one‑time boot menu (F12/F11/Esc on many boards) rather than changing boot order; try both "USB HDD" and "USB FDD" entries if present.
  • If the ISO/USB still shows a blank screen, burn the ISO to DVD and boot from optical drive as a fallback.

Quick install reminders

  • During setup choose Custom (advanced), delete/format the system partition and install to that partition.
  • After install install 64‑bit drivers and run Windows Update. A 64‑bit Windows will make full use of 8GB RAM, but older hardware may lack 64‑bit drivers—check the motherboard vendor if problems appear.

References in thread: ’s boot issue fits the USB/BIOS causes above; if problems persist, listing motherboard model and exact BIOS/UEFI options (no personal data) will narrow the fix.

Not enough information to help. What make+model of computer do you have? If it came with 32-bit Win7, are you sure it isn't a 32-bit processor? Normally, 64-bit systems come with 64-bit Win7 unless they were ordered with the 32-bit OS specifically.

Not all 64bit processors come with 64bit OS's. My i3 came with Windows 7 Home Premium 32bit and I'm now running Windows 8.1 Pro 64bit on it, 3 years later.

Maur.stape, there's no way to upgrade your infrastructure. Your computer either supports a 64bit system or not. If not, you have to upgrade your CPU to a 64bit-capable one. If it is, what you need to do is install a 64bit version of Windows 7.

Get a Windows boot disc/drive, boot from it (by selecting the disk/drive from the boot order menu in BIOS during pre-boot) and choose a 64bit version of Windows during the setup process. Once installed, you'll have 64bit Windows and you'll be able to use all of your RAM.
