First of all, please excuse me, I'm very non-technical. Some basic details of the set up: - Windows XP Professional Version 2002 Service Pack 2 - Internet Explorer Version 7 - Laptop: Compaq N620C 1.4GHz, 512Mb RAM The machine is an ex-company laptop, which a colleague rebuilt. I have no XP discs etc. When he had done it, he mentioned that the hard disk was making noises, consistent with possible failure. A crash followed about two months later, BSOD, but I managed to search for the error code and follow advice to get it going (via disk checking/fixing, my memory is vague and I didn't keep the details). This happened again, and a third time. On the third time, I subsequently found that Internet Explorer would open, and show the first page of the chosen site, but if I clicked in any links in the page it reported that it "has encountered a problem and needs to close". If I click on the link, the dialog box states: Error signature Appname:: iexplore.exe Appver: 7.0.6000.16512 ModName: unknown ModVer: 0.0.0.0 Offset: 00000001 Clicking on further details provides a huge amount of data, starting: Exception information Code: 0xc0000005 Other software on the machine still seems to work and, contrary to my expectations, the hard drive hasn't failed now for a few months. If working properly, the machine would be very useful for my son to use, for homework etc. My colleague works elsewhere now, so I can't ask him to help. Given I have no discs, what are the possibilities/options for fixing it? For example (and I hestitate to say this), would downloading IE7 and copy/pasting iexplore.exe into my setup work? (or cause more problems!) Thanks.
