I had my computer repaired about a year ago (give or take a month). The repair involved having the LCD monitor completely replaced. It reportedly was a loose connection which yeilded colour blocks down half of the screen. Prior to that I had a fan replaced due to high pitch noises and complained of heat issues. About 3 weeks ago I had my power adapter replaced. The cord came loose--I'm pretty sure it came loose from the issue I am about to discuss.
***Please be sure that I NEVER place this computer on my lap. It's always on a desk surface. I made two little metal lids that I use to tilt the base to allow for more air-flow.***
I am experiencing similair heat issues as to those prior to having my LCD monitor completely replaced. Watching movies through quicktime/youtube/VLC cause my computer to skyrocktet to heats above 100'C and it eventually shuts down. By shuts down I mean the video becomes choppy and unwatchable. I am aware this is a mechanic developed to reduce heat by shutting off one of the graphics cards. The heat issues started happening roughly 3 months ago. I looked into the issue and found a 3rd party program--SMC Fan Control--that enabled me to crank my fans. It feels like I'm over-clocking my system all the time as of the past 3 months.
Until 3 months ago I could watch a DVD on VLC while working on a powerpoint presentation in Microsoft Office 2010 and have heat of 70"C. Now it goes up to 90'C.
Until 3 months ago I could play WoW on low settings in the main city and it would sit at around 75'C. Now it jumps to 100'C on low settings in the main city.
Until 3 months ago I could play Sim City 3 on low settings and it would sit around 65'C, now 100'C.
Using this 3rd party software--SMC Fan Control-- has helped manage the heat. I can use my computer the same as I did for the first 9-10 months. However, I feel as though I'm suddenly over-clocking my system. This is only a bandaid. It's showing signs of what I saw before. Chunks of colours on my screen, black and white snow and total shut down. This is happening at increasing rates as time passes.
I cannot stress how well this computer worked for 9 months. I could watch a movie while creating spreadsheets in Excel without breaking 75'C.
This issue eerily reminds me of a certain class action law suit regarding NVIDIA cards being defective and causing heat issues.
Please help! These computers are NOT cheap.
