Tempuratures are around 60*c under load, 45*c normal (I put new thermal compound on), this laptop has three problems: -It switches off randomly occasionally, games alt+tab to desktop then power goes - not battery drainage. -The fan sometimes makes a really loud grating noise and it has to be switched off+on to stop it -The fan randomly speeds up very quickly for ~5 seconds, causing FPS to drop to about 1 (not helping midtown madness ) -I often get graphics problems, e.g everything goes red and pink then goes back, or white dots. Sometimes the display will go very fuzzy and will have a scroll effect (like when you film a screen and there's bars going down it) and it will not respond to any key presses, then turns off. Specs: 192mb onboard RAM SiS M650 Onboard Graphics (64mb) 2.0ghz Celeron - 512kb Cache What actions should I take with this? Thanks.
