My computer gave me a heart attack tonight. Was playing UFO:Aftermath when the the whole thing locked solid with corrupted graphics. did a hard reboot and the dam thing locked on identifying the graphics card, A restart later it makes it to windows and dies again, so I pull everything and reconnect the power and monitor the monitor, try again, boots ok so I plug in the USB keyboard and mouse and the thing locks. open the side panel looks around, powers it up again, all fans spinning except I notice the second fan on the PSU is looking a little limp but i have no reason to think its a problem as its a long running thing. Starts thinking to myself great, hopefully just a software issue otherwise I am screwed because I cant afford to replace anything hence the 7is yr old tech in there. couple of hours later as i think about going to bed i power it up again and all seems well, hopefully it's just an overheat so ripping all the fans and heat sinks where possible tomorrow and giving them a good shake and hoover to make sure they all working properly, well CPU fan will stay in place if I cant find my tube of thermal compound.
