How come my computer is still slow after I run defrag and antivirus software?

by on August 9, 2010

Q: I need help with my computer. It keeps freezing & is really slow whenever I turn it on. Its a 2008 Dell Inspiron 530 Windows Vista Home premium 2GB RAM 320GB Hard drive. I’ve done all the necessary Requirements Disk Defraging, Error checking, Disk Cleanup, Scanning for viruses. Many Times it Goes Completely Off its head and crashes/shuts down. Once it came up with Hard drive Disk Error when Booting but then it went away. And sometimes it shutdowns & when I turn it back on doesn’t come on instead it beeps Continuously until I turn it off, Then I wait & the next morning it starts again. Also sometimes I hit a few times it and it comes back on. What can I do?

    If you’re having issues getting it to even begin to boot to windows then you’re likely experiencing some hardware issues. Usually this would be one of the RAM sticks going bad or the hard drive starting to go bad.

    Here is how to test each of these.

    To test the RAM use MemTest86+ :

    This program needs to be loaded onto a USB thumb drive or burned to a CD/DVD or a floppy disk and then booted from.

    To test the hard drive, try Seatools for Windows:

    Both of these tools are free. I suggest using some of their more aggressive tests which may take a few hours but are worth it for troubleshooting.

    If you get errors with either tools then you’ll want to replace the bad parts, make sure to check if they are still under warranty.


      Okey man i ran tests but Seagate Came up as Fail What does that mean. What Test in do i pick as well. Thank dude 🙂


    It should have given some more details beyond just “fail”.

    Regardless you’re hard drive might be dying. I suggest you make sure you have all your important data backed up.

    If the seagate test program didn’t tell you, open your case and see who build the hard drive. It’s probably Seagate, Western Digital, or Samsung. While you’re in there write down the serial number and model number from the hard drive.

    Now go to the website of your hard drive manufacturer, and follow their instructions for warranty support. Many drives have 3-5 year warranties so you may still be covered. Follow their instructions to confirm warranty, as well as whatever tools they say to use to make sure that the drive is bad.

    As for the memtest, if you have a USB Stick available, download that version or you can use the ISO version and burn that to a CD/DVD using your favorite CD Burning software.
