Thanks in advance for any help offered...
Basically, recently my main PC (a now ageing rig of AMD64 3500+, 1024mb RAM, 250gb Maxtor HDD, ATi x800xt 256mb) has started having a very unusual problem.
Simply, ocassionally there is a 'Clicking' sound from the computer, similar to that described by people with HDD's they were informed were 'dieing'. The computer freezes up completely, including sound output, for a number of seconds, before returning. This often repeats every 10-30 seconds. Also, I have been able to determine that coinciding with these temporary freezes, the CPU usuage is recorded as spiking to 95-100%.
However, the unusual complication in my scenario is that this problem occurs ONLY when a game attempts to access the internet, with about 50% chance of this happening on Warcraft III, 100% chance on C&C Generals, 100% on Navyfield, 50% on Battlefield 2142. Sometimes, I can play entire gaming sessions without 1 instance, and others as soon as I click 'Multiplayer' there is the 'click' from the PC, and the sound of the HDD spinning back up.
Does anyone have any clue whatsoever as to what to suggest?
Note: I have already started backing up important stuff onto a secondary HDD as precaution.
