Windows 7 freezes at Starting Windows screen

[sjn2009]

Have you tried clearing CMOS?

Yes I tried this already to no avail.

Well thats your issue right there...
He's running a Celeron...it calls for 4 6 or 8core CPU's
It will run on 2G but they recommend 4G

It's clear from what i read you are asking the PC to do something it's not even close to being capable of...
Hope you got a good deal on it because you will need some hardware upgrading.

So did him trying to install it somehow mess up the computer?
Also I doubt he will want to upgrade his existing PC. The case size is terrible and I personally wouldn't want to construct that for him. I'd much rather just start fresh, a lowball estimate of the computer you describe is $200-300. That's what he spent on this computer, so I'm sure he won't be happy, but that's what happens when you buy instantly outdated computers at walmart.

Edit:
I'm reading that the memory requirements are min 1 GB, and doesn't mention anything about the processor requirements.

His system is inside specs.

If you want to run Windows 7 on your PC, here's what it takes:
    1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
    1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
    16 GB available hard disk space (32-bit) or 20 GB (64-bit)
    DirectX 9 graphics device with WDDM 1.0 or higher driver

From MS site.

Geek you should visit the site and check the apps requirements to advise on a replacement unit...

This is From the Site...

The MBiard and CPU are probably 399 by themselves...

I put the hard drive into my computer and re installed windows 7 using my disc. However, this has not solved the problem and it still occurs in the emachine.

That's usually not a good way to install an OS unless your computer is exactly the same model as his.  Have you looked in Device Manager on his computer to verify all devices appear OK there?

When you reformatted the hard drive, which probably had a recovery partition on it which was probably drive D, are you sure you erased the entire hard drive or just drive/partition C?

You can't get to device manager, because you can't get past starting screen.

And when I reformatted the drive I did remove all partitions.

Patio, please remove my foot from my mouth. 
That program can run only on a few machines.
The owner should not have tried that program.
The OP erased the whole HDD. Iincluding recovery partition.
He may get Windows 7 back only with help from the maker of the computer.
Buying a new retail version of Windows 7 is not a good option.

I am out of suggestions and will now keep my mouth shut.
But the computer is not broken. Just messed up. Sorry I can't help.

Well thanks for everyone's time, but this is beyond my abilities so I'm giving it back to him. He says he called pro tools support and that his computer was fine. So I'm not sure what will happen to it, and ill continue to check here in case something works.
