Hi, My PC will not start up Windows XP. I have had it for 5 years without any problems, it is now the secondary PC for my kids to use. When powering on, you can see the memory loading up, then the screen momentarily shows the Intel processor page as normal, then a vibrating noise which I assume is the hard disk starting up, then nothing. I opened up the PC, reseated the memory, checked for loose connections but nothing obvious. Anybody any ideas, or is it a trip to PC World for a new one? Thanks in advance for any suggestions PS - I tried inserting the recovery disks but nothing happened!
