The biggest problem is finding out what the specific chipset can handle in terms of CPU upgrades. ATM, I can hardly find any info about your motherboard. This may be something you can talk to AMD/ATI about through their support.
The other thing you need to consider is whether or not you are actually going to be able to find a CPU that will work. You may want to consider saving your money at this point to get a new system.
well I upraded my memory from 256MB to 768 and the hdd from 20GB to 250GB.
The RAM works fine but with the HDD upgrade I have the following problem:
Every time I the HDD is working the CPU goes up to 90-100% and the whole laptop is VERY slow. Do you know why this could happen?
the new hdd is : WESTERN DIGITAL WD2500BEVE HDD 2.5'' 250GB ATA
the old hdd is : toshiba 20GB, IBM IC25N020ATCS04-0, ATA-5, UDMA-100
I used aida and did a few benchmarks which were I bit weird...
