I cheked it out and :
Processor Name: Intel Pentium M 730
Processor Speed: 1.6 GHz
RAM: 512 MB
Hard Drive Capacity: 60 GB
Intel Graphics Media Accelerator 900 GM
The card would be holding you back but for COD it should stil play fine.
A good server...
Your looking at at least one Xeon (dual core) but two 2.66's for top peformance..
2GB PLUS of RAM
And a minimum of 5mb download, 512k upload.. although 1MB upload would make a great server.
I had the exact same problem, i ended up getting a new PSU, extra RAM (for the sake of it) and a new mobo... doesnt sound promising for you but this is a common problem thats unknown to people that havnt heard it... but it is common just no1 knows the solution as thers so many
