OK I finally found some useful info. I am including a URL for specs and drivers. According to the spec sheet the computer is suitable for 64 bit but you may be having driver problems. I you can download the program from MSFT that checks your computer for Windows 7 suitability.

If you need drivers this program will tell you. Ralph

It looks like your laptop (product page) might have these processors:

• Mobile AMD Sempron™ 3200+/3500+ (1.6/1.8 GHz, 512 KB L2 cache)
• Mobile AMD Sempron™ 3400+/3600+ (1.8 GHz/2.0 GHz, 256 KB L2 cache)

According to Wikipedia AMD Mobile Processors your processor has AMD64 technology, which is 64 bit.

So if you have 64 bit Windows 7 your processor DOES support the 64 bit OS, but like Ralph said you may have driver issues.

Upon further investigation if you check out the downloads page for your model they have placed a nice red 'X' in respect to Windows 7 support. You could try downloading the latest drivers anyway to see if that fixes any of your issues.

The processors is soldered and can't be replaced without mechanized soldering tools and a solderable processor. These processors are hard to find.

however, i may be wrong

All about upgrading to Windows 7:

"Upon further investigation if you check out the downloads page for your model they have placed a nice red 'X' in respect to Windows 7 support. You could try downloading the latest drivers anyway to see if that fixes any of your issues.'' Mostly the site is full of bunk. I have installed Win 7 on 5002wmi, 5240x3, AOA 110x2, AOA 150, and A0751h(before the A0751h was approved). I also am a M$ Beta Tester - Win 7. the Editions I tested and installed on above mentioned = HomePremium-Professional-Ultimate. The only one that has PROBLEMs is the Win7 Approved.(The NEW BIOS 2.1 SLIC problem (hence I had to convert the GRAPHICS down to BASIC). while the unapproved works 100%. All versions were x86 (32bit). have not tested x64 on the Acers... If I convert the A0751h back to NO SLIC BIOS the Graphics works perfect. DUH DUH this is also with 1 Unit sent back 3x to Temple. and reported a 100% PERFECT. yet customer had (sudden FREEZE problems)_FREE MEMTEST will also tell you if you have dual core or single core. or simply choose x64 to install - if allowed then you know x64 works... if not allowd the program simply TELLS you not approved. and you can select x86...

As pointed out your laptop is already 64 bit capable, so there is no need to upgrade nor would it be capable if already 32 bit.

To see if you are running 64 bit do this: Open start menu > Right Click Computer > Click Properties > Find in the window the 'System' section > under that find 'System Type' it will say '64-bit Operating System' if it is.

Also as pointed out there is no Win 7 driver support much less 64 bit. I was going to suggest to try the 64 bit Vista drivers, however upon looking it appears there are no 64 bit available.

A small side note is there is no need to run a 64 bit version of a OS unless your computer is using more than 4 GB of RAM; 32 bit versions work just fine.

You have to see a list of processers that can be used to upgrade your laptop. Or you could find out what cpu socket you have and see what other processors have the same socket type.
