Re: I am not making this up...
"So I opened the lid, after removing a humungous pile of dust balls that were perched over the DIMMs (can't recall exactly what was in the PC) and those by the CPU, then funnily enough it worked absolutely fine."
Back in the days when TVs were not only rare but also magnificent pieces of floor standing furniture my aunt, one of the lucky few to own one, looked in the back of hers. She saw a lot of dust. As she liked things to be kept clean she attached it with the vacuum cleaner. Not a good idea.
