Inspiron 1720 - Vista - "Not Responding" on applications

by HuiGao / May 12, 2009 1:44 PM PDT

Hey cnet,

My computer has been having some problems lately, as you may now have figured out. A few days ago my laptop was working fine, but now applications randomly go "Not Responding". For instance, I was just typing this in Mozilla Firefox and it started "Not Responding". If I try to switch to anything else, i.e. Microsoft Word, Thunderbird, even opening the start menu or right clicking on the desktop, those applications also go "Not Responding". Sometimes the applications fix themselves in about 5 minutes, other times a manual restart is necessary. My CPU according to task manager is about 4% (aka not spiking to 100%). I tried booting in safe mode and it seemed to revert to normal settings each time.

So cnet...I was just wondering if you knew what the cause of this problem is...hard drive? Processor? Software/virus? Even better would be how to fix it, if I can do it without taking into the shop. Any feedback would be greatly appreciated, as I nor any of my tech-friends have encountered this type of problem. Thanks!!

I'd go in safe mode and...

.. run antivirus scanner(s) [not at the same time, of course]. If there's a virus chances are it will be caught.

Other than that you 'might' be having driver problems (as I was having when the start bar would loop in Not Responding). So download the newest drivers for your Dell @ the Dell's driver download center.

I did manage to boot into safe mode and ran a virus scan but nothing came up. I tried going on Dell and finding drivers but I'm not sure how to check if mine are all up to date.

Check this

It's something like...

rightclick My Computer > Manage >

Look under there and look for something called like... Device Management, or something.

In there you'll have a list on the hardwares/devices that you use i.e. SATA Drive, WIFI, Processor, etc.

Right click, update (if it's not that, doubleclick it, driver update).

Depending on how old your laptop is w/o driver upgrades, chances are there are a few new ones out.

I'm running a hard drive diagnostic right now and I've gotten errors in both the "Read Test" and "Verify Test" portions, specifically Error Code 0F00:1A44 and 0F00:0244. Does this mean that my drive is trashed? The drive is 320G, only about a year old...

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
