my laptop isn't making the fan noise

by swimlight / January 1, 2014 8:53 AM PST

so i have a hp pavilion dv7 2043cl laptop i got in june 2009. until now, it had no problems running modern games. i was playing arkham city, portal 2, farcry 3, with NO problems. however, a few days ago, everything started to lag. and then i noticed that the once obnoxious noise of the fan has suddenly stopped.

now my labtop is quiet, which is nice, but i feel like the CPU isn't going as fast as it should. browsing a website takes 100% of the cpu power right now.

is this a fan/cooling issue? or is my cpu/memory just dead?

any ideas/suggestions would be extremely helpful

Is there any air coming from the vent out? You may just need to get a can of air and do some cleaning. The intake is generally on the bottom and the vent out on the side. Blow air, at a safe distance, from the bottom intake, with the unit powered off. Sometimes dust build up will stop a fan. IF the fan is dead, I'd suggest getting it replaced asap since overheating can and will kill a CPU.

Get a can of air and try a clean out as suggested...there should be some air flow from the vent out, if not, it is time to get the CPU fan replaced, if you cannot do it yourself, I'd suggest taking it to a techie shop, it is not a huge job.
