Windows 7: Installing 64 bit problems

Installing 64 bit problems

I just built my new PC, and I installed 32 bit windows on it. Now, I want to install 64 over the 32 bit installation. Putting the 64 bit disc (legit copy) into the PC and clicking on setup, or any files on the setup disc, it says "This version is not compatable with the 32 bit version of windows. It does this when the disc is in and it says it if I put the files on an external hard drive and run it from there. Trying to boot from BIOS with the disc doesn't recognize a windows setup on the disc. Please help!

AMD Phenom II x4 965 3.40ghz black edition CPU
MSI 880gm-E41motherboard
Radeon HD 6850 video card

You cannot upgrade from 32 bit to 64 bit. You need to do a Clean Install Windows 7

If you have an upgrade disc, then see here: Clean Install with a Upgrade Windows 7 Version

Thank you for the response!

I actually tried the Clean install ( Normal Install ) Method. But I cannot do this, because I cannot access the BIOS on my motherboard. Seems to be some sort of problem, but I will deal with that later.

I actually think I cannot access it because I am using a USB keyboard. But anyways, I cannot get into my bios to boot from the CD. What is a alternative?

There is a bios update for my motherboard which supposedly allows a USB keyboard to be used to access the BIOS, but i heard that it can turn your motherboard into a brick. and I don't want that.

Using a USB keyboard to get into the BIOS shouldn't be a problem.

As far as I'm aware you need to tap the DEL key at startup to get in if you're using an MSI motherboard.

Actaully it would if the BIOS/Motherboard isn't configured to take commands from a USB keyboard while posting. However most newer motherboard usually don't have this issue. This is where system specs would be helpful.

As to the BIOS update, yeah, if you don't know what you're doing or don't follow the directions posted for updating the BIOS you will brick your motherboard. Reading is a must here!

As for getting into the BIOS - If your MB won't accept a USB keyboard you can find a USB to PS2 adapter and use that on the keyboard and then try to access the BIOS. They can be found for about 3-4 bucks. Or you can just find an old PS2 type keyboard.

I just removed the CMOS Battery on the motherboard and the thing allowed me to use the USB keyboard.

But anyway this is now solved

Be aware that removing that battery may also reset your BIOS settings - meaning the settings that were there for you CPU, memory, and other stuff may have been reset. This may also include your clock. So..... if your PC starts acting strange, you may need to look at the BIOS.

Just something to think about.

Good luck.
