I ran HD Tune on my VAIO and the average Transfer Rate is 1.5 Mb/s and the Access Time is 20ms. CPU Usage is 98%!!!
I get sound stutters and I tracked it to the Hard drive and it sure looks like it.

Re: Transfer Rate is LOW!
If you?re getting odd noises coming from the hard drive you may be suffering from read errors. Windows has a utility called chkdsk that can test the hard drive readability and perform repairs in some cases.
-Click on Start, then Run.
-In the Open field enter ?chkdsk /f /r? and click the OK button.
-You will be prompted by and error that chkdsk cannot run but will ask if you want to schedule it to run the next time the system restarts. Enter ?Y? .
-Restart your computer,
-Chkdsk should run after your system reboots. It will check the integrity of your hard drive and ?repair? any spots on your hard drive it can?t read. Actually what it does is move the data in the spots it can?t read and then marks the spot so that Windows does not use them in the future. The process should take a couple of hours, depending on how much information is stored on it.

First, I appreciate the details provided in your question. Thanks! The specification of your laptop are fine and enough to run and support Vista. It is true that greater number of processes and CPU usage causes, but normally the machine can handle it well if it gets proper ventilation. Laptop heating issue generally occurs due to fan failure, which may damage the system, if not checked properly. Another cause of overheating is the dust present inside the laptop, which clogs the fan and heatsink. I suggest that you should get you laptop checked by a professional for servicing (if required). I believe immediate action is required to prevent any damage to your machine and data.
Hope it Helps! Let me know if i could be of any further assistance. CreativeTECH
Try to monitor the CPU usage before opening CROME. If it is normal before opening it then there is some process under CROME which takes you CPU usage report to GOOGLE on this. and remove it through Add/Remove programmes under control panel.
Try to use Firefox instead of CROME.
If it happens again then there is some thing wrong with OS( most probabaly Spyware or trozen).
i) LOW DENSITY modules have 100% compatiility with ALL systems and ALL chipsets. HIGH DENSITY modules only have 10% compatibility
here compatablity means LOW DENSITY RAM are accepted by all system(100%) or any make system.. HIGH DENSITY RAM are accepted by 10% by only some system or computers...
ii) in order to check system performance or amount of Computer RAM usage press the ctrl+alt+del simultaneously a new window(window task manager) will appear showing:
CPU usage: showing the amount of CPU or processor utilized at that particular time. PF usage: showing the amount of RAM memory utilized at that particular time. Physical Memory: showing Total RAM Memory, Available Ram memory....
iii) baiscally they are two types of RAM they are:
DDR1:which is older one supported by older system or older mother boards which is costlier DDR2: which is latest one supported by all new system or new mother boards which is less costlier
DDR: double data rated ram......which will send data at a double rate compared to SD RAM
iii) here color doesnt matter, these slots either support DDR1 or DDR2 but not both at a time
DDR1 has 184 pins or gold plated pinssss... on the edge of the RAM DDR2 has 240 pins
so difference doesnot allow DDR2 to placed in DDR1 motherboards or vice versa...
iv) it does have anything to do with no of chips on the RAM but they only differ whether it is DDR1 OR DDR 2(DDR2 are much faster than DDR1)
NOTE: whatever may the the RAM, each RAM has FSB(called Frequency...) which determines the frequency of rate at which data is tranferred from RAM to processor(CPU) usually in MHZ such as FSB 300, 400, 200 , 333...................
more the FSB the faster data is transferred to the processor(CPU)
dont worry even RAM with less FSB's work well with the processor....having 1 GB RAM or 2 GB RAM is engouh, it only matters with the speed of CPU ... but not RAM......
A cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is shorter. Cache, therefore, helps expedite data access that the CPU would otherwise need to fetch from main memory.
A cache is a block of memory for temporary storage of data likely to be used again. The CPU and hard drive frequently use a cache, as do web browsers and web servers.
A cache is made up of a pool of entries. Each entry has a datum (a nugget of data) which is a copy of the datum in some backing store. Each entry also has a tag, which specifies the identity of the datum in the backing store of which the entry is a copy.
When the cache client (a CPU, web browser, operating system) wishes to access a datum presumably in the backing store, it first checks the cache. If an entry can be found with a tag matching that of the desired datum, the datum in the entry is used instead. This situation is known as a cache hit. So, for example, a web browser program might check its local cache on disk to see if it has a local copy of the contents of a web page at a particular URL. In this example, the URL is the tag, and the contents of the web page is the datum. The percentage of accesses that result in cache hits is known as the hit rate or hit ratio of the cache.
The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus
