Hi,
I have a Dell Inspiron 1564 (Intel i3/4GB RAM/320GB Drive/Win Home 64bit). Great machine and I've had almost no trouble with it. Almost. One thing that it has done about 6-7 times in the past 4-5 months: Randomly, the screen will go blank, lit to a solid color (not bluescreen of death), and is accompanied by a grating, buzzing, alarm noise from the speakers. This is not a slight buzzing. It's a "Whoa, something's really jacked up!" sound. All I can do is unplug and do a hard reboot. This is pretty random and doesn't appear to be attached to any particular degree of multitasking. I run Adobe CS4, OpenOffice, browsers, etc in any combination at any time.

1) Is this heat related? I work on solid surfaces and keep the fan/vent clear from obstruction.
2) Do I have bad memory? I usually run at about half of the RAM installed.
3) Is it a CPU issue?

Thanks for your input.
-Joe

Run a virus scan, know some old DOS viruses does similar stuff, although its Vista and not DOS, it still could be a virus

Hello and welcome to the forum!

Might be a hard drive that is starting to fail.
I would recommend backing up your personal data somehow, just in case.

If we knew the hard drive manufacturer we could have you run their diagnostics to test the drive.

Go into control panel - system icon - hardware tab - device manager button.
Expand the disk drives category & post what it says there.
That will identify the drive manufacturer for us & we can get you the utility.
In the beginning there was the command line.

You can run the Dell diagnostic utility by pressing f12 when the Pc is booting up and you are presented with the Dell splash screen.

Thanks MarkGS! I always forget that Dell has that.

When you test the hard drive do the full test.
It could take an hour or better to run.
In the beginning there was the command line.

I've tried the Dell memory diagnostic and the Win 7 memory diagnostic a few times. In all cases, this problem occurs during the execution of the diagnostic during different times in the process. Good bet my RAM is shot?
Thx
Joe
