It would seem that you have a virus roaming around in your hard drive and also a problem with The IE, this could be just 1 problem.
(1) I would suggest to you to go to your internet broser and reset it, this will restore your IE to initial, Note that all your add-ons will be deleted, you will eventually re-install them as needed.
(2) run a deep (full) virus/spyware scan to see if you find anything, also note that once hidden malware gets in your system it is hard to remove it. The other part to this is if your hard drive is making noises, then there could only be 2 things wrong, The Hard Drive itself which highly unlikely, the other part to this is the virus have a tendency to hide and cause your hard drive to make noise (Grinding Noise).
Try this 1st: reset IE completely, run *** clean, run defragmenter,run checkdisk (CHKDSK/R)after the computere sarts up and all programs are loaded go to computer, right click, click properties, click advance, click virtual memory settings,click advance, click change, check NO PAGEFILE, at this point it will ask you to restart, do so and then run the defragmenter again, you will notice that your page file will move to the right (GREEN)once this is done put the pagefile setting back to system managed,check it out, I am sure that it will gain up to 10 seconds actually if your system is running right from a power up, BIOS Load should be 10-15 seconds, Windows Load 20-40 seconds and than the security should take another 20 seconds, this is from an initial start, wish you luck.
