Can I replace the CPU of my Dell Vostro 3700 laptop?
I have a 3 year old Dell Vostro and I think that the CPU is getting "tired". It runs at 100% too often, even watching a video on YouTube would make the fan run very fast. I cleaned it several times so it's not heating too much at the moment. I found the CPU on eBay and I would like to know if 1) replacing the CPU would fix this issue and 2) if it is doable and not too risky.
When the fans run fast, there is no drop of performance, but it just gets noisy and the laptop starts heating.
I don't think it is a software issue because sometimes it does it when I just open Firefox and Thunderbird. I checked the task manager and I just see that one application is consuming the CPU, which shouldn't be the case. It does the same thing on Linux and Windows. Sometimes it does it at the log in screen.
Here is the CPU I found : http://www.ebay.com/itm/140616103272
Thanks for your tips and advice.
