Tell me about how often you use canned air.
And at home I have a Dell 15r. Installing Windows 7 is a PITA as I would have to do the usual driver hunt at Dell and then add Quickset and more.
Use Dell's recovery media as I am no longer convinced that everyday folk can install Windows proper today.
I've had this laptop about a year now, it's a Dell Inspiron 15r (unfortunately I don't have the exact specs in front of me, writing this from school). A couple of months ago I was forced to reinstall windows 7 after some major boot up errors, so it's a pretty fresh install. Other than some basic programs (CCleaner, Defraggler, VLC, etc.), I've only loaded onto it Matlab and Creo 2.0, and a couple of lower resource games.
Performance had been lagging somewhat lately, but not enough to really concern me until last night when I was unable to even browse the internet without it crashing. I defragged, use ccleaner, rebooted, and checked all the drivers. No luck, still slow. After boot up (and waiting a few minutes to make sure it's finished) it took about 2-3 minutes to open Firefox. Opening the My Documents folder wasn't much quicker. Even watching videos that are loaded onto the computer will stall and eventually crash the computer a few minutes into the video.
Avast is running a virus scan right now, but I'm not expecting anything major from that. Barring some evil virus that I've somehow picked up, I'm stumped on what's going on. I suspect the hard drive is failing, and am hoping it's not the processor, but don't know enough about the hardware side of things to know what to look for if I open it up.
If anyone could provide any advice on where to proceed from here or assist me in figuring this out I would very much appreciate the help. Thanks in advance!
