Cutting your losses
Today's laptop has strange problems that I have failed to explain. The Windows firewall service is missing. All downloads and attachments are falsely reported as infected and are deleted - though the machine is free of malware. I would love to spend the time to get to the bottom of this and find out why - but realistically, it is quicker to just reinstall!

Overheating
I have had two recent repair jobs which have been debilitating but easy to fix!
A Dell Dimension 5000 was shutting down a few minutes after starting up - and this was caused by complete blockage of the air intake holes. This model has a large slow-moving fan which draws air in through a large recessed vent in the front panel. The intake was totally blocked with dust, and on cleaning this out normal service was resumed.
Another desktop was shutting down seconds after powering up - and this was caused by the CPU heatsink and fan being dislodged.
