looking at your files this would be a Dell Inspiron 1545 which has a dual core processor and uses DDR2 ram running windows 7 OS 64bit ?
your .dmp file shows a 7e in bluescreen view and in windows debugger the same stating : Probably caused by : discache.sys ?
this could be drivers or BIOS or hard drive or possibly antivirus or third party firewall so as a good starting point I would get all your drivers up to date first ?
To do this I would check your BIOS as there is an update available bringing you up to 4/27/2010 and then update all of your system drivers such as chipset and gfx card, sound card, network card Link Removed - Invalid URL .....
Also get a monitor on your temperatures which currently show in your CPU-ID report...
