I find that when my laptop gets hot it runs slowly and on my old laptop when the fan broke it started randomly shuting off. It could be that you just need to wipe your hard drive or that you are now runnign larger more intensive programms that take longer to boot up but, if you want your laptop to last you may want to invest in a cooling pad with external fans and some cans of deionized air to clean your fan off. You can get the cooling pads pretty cheap on ebay and the cans of air anywhere.
Problem: Laptop takes forever to boot up. After I hit the Power button, sometimes it hangs for 30 secs to 2 mins before it the system starts to boot. I wonder if this is caused by the hard drive? Time for a replacement?
I've had this laptop for almost 2 years now. It was new when i bought it. It's a Toshiba Satellite M35x-s161. I've been using it quite a lot.. sometimes i leave it on for days...
