PC problems

[cawill]

I currently have two problems with my PC(Sony Vaio PCV-RS704)

My usb ports (front and back) and memory card reader no longer work and are not detected by both windows XP and Ubuntu. This happened after I had to reset the cmos settings using a jumper on the motherboard as my PC showed no output on the monitor (with 2 different graphics cards). My usb ports should be connected correctly as they give power to usb devices. Is this easily fixable?

I want to buy a new pc in a month and my vaio has a Pentium 4, 3.4 GHz processor which I would like to remove so I can use it with my new pc but there is a heatsink/fan on top of it with no obvious way of removing it, can most pc's heatsink's be removed?

Thanks, Chris

I switched the jumper to the other setting and then switched it back before starting up, using pcu-z I found out my motherboard make and found out that their are problems with the usb devices on quite a few sony vaio's.
