Please help with an ongoing issue I have..I have noticed my screen freezes at approx 60degrees celsius and freezes on the current screen displayed..there is no blue screen and the screen will stay frozen until I power off. When i power off I cannot turn it back on again for approx 15mins as it just shuts down immediately.I have cleaned the fan and applied thermal paste..Problem still persists.
Sounds like a defective on-board video controller. This is very common with these systems. So much so, that many systems (incl. the DV6) were part of a class action lawsuit/settlement (since expired). Your only option may be to replace the system as a whole, or the mobo (at a minimum).
