Up until about 5 months ago I had windows 7x86 on my laptop. A friend convinced me that my laptop would run smoother on 64 bit, and that photoshop would work faster. The problem is that since I switched to 64 my graphics card score dropped from 5.4 to 4.1 (that's 1.3 points). Another issue would be that since I switched to the 64 my hard disk drive occasionally freezes and I have to restart my system when that happens.
Do you think these problems are related to the x64 installation?

I doubt that the freezing is caused by using 64 bit Windows, I would suspect memory problems are causing this and that the errors are probably more apparent on 64 bit Windows as more of the memory is being used. Try downloading and running memtest86 4.0a
There is no point in using 64 bit Windows unless you have 4 or more gigs of memory. 64 bit Windows is slightly faster than 32 bit Windows but uses (needs) more memory which if you have less than 4 Gigs of memory cancels out the speed advantage. 32 bit Windows is more compatible with old programs but can't use more than just over 3 gig of memory.
And another thing, when my laptop freezes it makes this high pitch sound, it's not too loud, but you can definitely hear it.
This happens, typically, when you have a heat and/or power issue. You can get a can of compressed air and with the power off, blow out the intake and exhaust ports to remove any dust build-up. Are you monitoring your temps? If so, what are your idele and loaded temps? If not monitoring, get hwmonitor and install it. You can get it at:
@COLGeeg I've installed hwmonitor but it doesn't seem to be any heat problem. I've attached a print screen with the test results.
@Zoron, I tried this too. I installed the latest drivers from the chip vendor.
The problem is still here. Thank you all for your advice!
