Windows 7 freezes when I put laptop to sleep

I am using a SONY VAIO NW120DS and just recently upgraded to Windows 7 from Windows Vista. Every now and then, when I close my laptop lid, my laptop does not go to sleep like how it is supposed to. Instead, the screen turns off, but I can hear from the sound and the side power light that the computer is still running. When I open the laptop lid again and try to use the laptop, it is unresponsive. This only happened after I upgraded to Windows 7, and it doesn't happen every time, but it happens enough that it gets extremely annoying because I have to force shut my laptop when that happens.
Sorry if this question has already been posted before - I am a new member of this forum. Thank in advance for the advice!

Hi Chronic and welcome to sevenforums

Sometimes win 7 and sleep/hibernate dont play nice with each other. Can you check the power plan settings for sleep and hibernation when on ac and battery.
Also are eyou 32bit or 64?

thanks

Update the chipset drivers and flash the BIOS too. If you choose to update the other drivers, use driver sweeper where necessary.

I'm using 64-bit windows. My power setting is set that whenever I close the laptop lid, it is supposed to sleep to conserve power while on AC or battery. Sleeping while on battery is especially important because I'm in university and am without AC for hours at a time.
Thank you so much in advance for the instructions and patience in helping me. I am tech-blind and barely know what drivers are... I just know that they are things that the system automatically takes care of! It's annoying when I'm in the lecture hall and I open the laptop lid, only to find that it didn't really sleep but the screen is blank and it is unresponsive. Thanks again.

"Windows 7 freezes when I put laptop to sleep"????
That's funny; Complete new install Windows7 64bit just solved this problem for me on my Toshiba.
Had the same problem but than in Vista 32bit.

So a complete install will fix the problem?
Arggh! Life is so time-consuming =P
Are there some less time-consuming solutions?

*bump*
I finally had time to back up all my files, but I just realized that I couldn't re-install Windows 7!
It won't let me.
I don't have a Windows Vista disc either...
WHAT SHOULD I DO??!?! *rips hair out*

Couldn't reinstall?

I popped the windows 7 install disc in my laptop and it told me that i already had windows 7, so i couldn't install it again.
