DELL M90 Window 7 -64bit (Slow?)

Hello,

After "fixing" my faulty Graphics Card I proceeded by making a clean instal of Windows 6 Prof (64 bit).
I have come to realize that the computer is not running smoothly. I get some kind of "lags" in the performance and sometimes becomes slower.

The speck is as follows:
Operating System
MS Windows 7 64-bit SP1
CPU
Intel Mobile Core 2 Duo T7200 @ 2.00GHz 47 °C
Merom 65nm Technology
RAM
4,00 GB Dual-Channel DDR2 @ 332MHz (5-5-5-15). Only 3.25 GB are actually usable from this Lap-top
Motherboard
Dell Inc. 0YD632 (Microprocessor) 47 °C
Graphics
Generic PnP Monitor (1680x1050@59Hz)
NVIDIA Quadro FX 3500 512mb (Microsoft Corporation - WDDM) (Dell)
Hard Drives
78GB Hitachi Hitachi ATA Device (SATA) 31 °C
7.200rpm

Could anyone give me some advise on it?
Am I being to picky with the Laptop or is there an underlined problem?
Hard drive maybe?
OS: maybe I should not run the 64bit version and go back to 32bit?

Thanks In advance!!

 

I would try the 32 bit Win 7.

 

Could it be just Windows 7? Maybe if i go back to XP?

 

i find Win 7 very fast and stable

so try the 32 bit OS and see how it goes.

 

M90 = 945 chipset, while it can "see" 4 GB, I believe all of them are gimped to like 3.5 GB or less. Lenovo restricted their 945 chipset laptops to 3 GB max, BIOS limitation. I haven't had an issue with Windows 7 and I ran beta, RC and retail for years and years now.

 

make sure you use original MS *.iso
most of custom *.iso's are crap.

 

I did a clean Install of 7-32bit, So far so good I will try running some programs now to see how it goes. The lagging is gone already...

I will post the progress for those interested

 

It seems that I get the CPU spikes after I use the computer for a little while. On Cold start it seems just fine its after I stress it that seems to malfunction.

My Ideas are:
Old thermal paste (On the contact with the heat sink) that has solidified from high temperatures.
Together with poor fan ventilation at the moment. Because I am currently running it with only the GPU fan and a Cooler deck. (I am waiting for the replacement part to install it)

What do you think about this?

 

Hard drive is holding you back. Get a 500 or 750gb 7200 rpm. Relatively cheap and will get you over 100Mb/s reads.

Video card will not support any of the 2D acceleration in W7 because the 3500M is not DirectX10.

 

Thanks Bokeh! HD was on my list just a little further back was thinking of (Western Digital Scorpio Black 320GB SATAII 16MB Cache 2.5 inch Internal Hard Drive OEM) what do you think?

The fact that the 3500m wont support the 2D acceleration means that slows down the system as well? Or is it irrelevant?
