Windows 7 keeps freezing and forces me to restart my laptop!

[Zek Tech]

Hello,
I am having a problem with my laptop, a Sony Vaio VGN-NS325J running Windows 7 Professional 32-bit upgraded from Vista Business 32-bit. For whatever reason this laptop just decided to start freezing on me (I can't move the mouse and num lock/caps lock doesn't work). It does it from hours after using it to right from start up. I have a hunch that it may be the speakers or speaker driver on here because whenever I move the screen slightly or bump the laptop, the speakers cut out.
Any help would be great,
Thanks in advance,
Zek Tech

(P.S. I did some testing and installed a 64-bit version of Windows 7 Home on here with all drivers and it forks flawlessly.)


Specs:
Brand: Sony
Model: VGN-NS325J
OS: Windows 7 Professional 32-bit upgraded from Vista Business 32-bit
CPU: Intel Pentium Dual-Core CPU T4200 - 2.00GHz

Chipset: Mobil Intel 4 Express chipset Family
HDD: 500 GB SCSI Hard Drive

Hey there, Zek Teck.

Those might be 2 separate issues. I'd recommend that you backup any personal data you may have on the HDD, just to be on the safe side. After that go ahead and download the HDD manufacturer's diagnostic tool and test the drive, to see what's the situation with it.
If it turns out that this is not an HDD related issue, it could be due to overheating. Another thing is a faulty RAM stick. It wouldn't hurt to update your anti-virus program's database and scan your whole drive with it and do the same with an anti-malware program. It could also be software related - when did this start at first, did you install any programs or update anything?
The truth is that there could be many reasons for this to happen and you'll have to do a bit of testing in order to figure out what it is. If you're not willing to do all that, then you could take it to a service shop and let the guys there figure everything out and fix it.

Hope that helps.
