I have a dell latitude d505 which was running good, a few months ago I had to have it repaired as it needed a new hard drive, along with that windows xp was reinstalled.

I didn't have a problem until last night, it was left running for an hour or so doing nothing, when i come back it froze on me. Since then I have realised it will only freeze when you try to open a browser(firefox or ie).

I ran a full virus scan using avast which found nothing at all. Im almost certain there are no viruses on it.

Looking around on the net I found another problems similar to mine and it was suggested he press f12 when booting up and run diagnostics. I did this but it comes up with "No dell diagnostic partition found". Im not sure if this has anything to do with it?? I tried to reinstall a few network drivers from dell website but absolutely no difference. Is it a hardware problem??

Thanks in advance

Whoever reinstalled Windows for you probably formatted the entire disk, wiping out the Dell recovery partition. Never mind - you don't need it for just one problem.

Whilst opening a page in Firefox or IE, right click the Taskbar and click on Task Manager. Click the Processes tab and then the box at the head of the column marked CPU. That should bring to the top, the process using the most resources so note which those are and post the details back here.
