1. If the case of that computer has never been opened - that is your first task.
As my colleague happyrock
AFTER YOU GET DONE CLEANING...
and running the hard drive testing tools and the drive passes the tests...
2. You do NOT have to download it to this
computer - you download it, make it on the CD, on another computer, and run it on this computer.
3. I appreciate this
Prior to trying to use the reinstallation CD, when I turned the computer on, it turned itself off after a couple of seconds and gave me a blue screen. That's why we were doing the repair instructions with the CD but it froze in the middle of that too.
We are therefore, establishing if the possible build up of dust in the cooling fins of the CPU and on the fans MAYBE a cause.
When you have inspected and cleaned - LEAVE the side of the case off WHILE you connect and switch on and ensure the fans are running.
If the ONE on the CPU - location as described is NOT running - shut down immediately.
Then we are ensuring that the HDD is good, as far as we can do.
4. When you have completed those tests if the HDD test fails post the results please.
If it passes try a boot to Windows - normal mode.
If that does not work try a boot to Safe Mode.
Clean as necessary
Run the disk check
If it fails post the results - including an indication of how bad the build up of dust was.
If it passes try booting to Windows - normal and safe mode
Post results and as before please indicate situation re cleaning.
