[Eminent]

Okay dont know how to describe this problem at all, so I just took a picture these two lights are consistenly blinking and it just recently happen, I also recently installed more RAM to my PC, but the PC is running perfectly fine or atleast to my knowledge, so I dont know what they are for, but here is the pic...I'd like to know what this is and fix it asap, anything wrong with my PC really bothers me and I try to fix it as soon as possible.

Does the light for harddrive still blink with activity?

Did what you said and didnt change anything, but not to be rude or ignorant...but I really dont think those two green lights are for my harddrive, I think my harddrive light is yellow, which would be the same light that goes on when I insert a disc and it's reading information, or when I open/shut the harddrive, correct? I may be wrong though, but none the less I tried what you had said and lights are still blinking, oh and if it's a bit of help at all, both green lights blink off and on at the same time, it's not one then the other.

I was actually just check to see if that would resolve the harddrive light from flashing

I know it seems strange
My wife's laptop use to flash like that
It's not a compaq, but a Dell

I found this when snooping around
Not your same problem, but it worked for hers

We have an answer folks.  I will just summarize what we know so that this Forum discussion thread can come to closure.  To find out why our hard drive light continually blinks we ruled out all of the following: disk indexing activity, anti-virus programs, network activity, and all such tasks that may be running in the background and accessing the hard drive.  Remember, the symptom was an extremely constant blink, for about a quarter of a second, repeating approx. each second.  One of the contributors to this discussion suggested that it was the system checking the CD or DVD drives for an inserted disk as part of the "autorun" feature.  This polling of the CD or DVD drive is actioned through the hard drive controller.  We found that by disabling autorun, the problem almost completely went away.  Almost completely, because there is a second cause happening simultaneously.

 In the HKLM_Software_Microsoft_Windows_CurrentVersion_Run registry keys, there is a TSR applet installed by Dell called "DSentry".  This ALSO causes hard drive blinking because it is polling your DVD drive to see if a disk is inserted.  DSentry was added by Dell to prevent spyware programs on movie DVDs purchased from mass distributors from sending info on what movie you are watching to their database via the internet.  So I commend Dell for adding this, but I scold them for not telling anyone about it, esp. not their technical support people.  DSentry.exe causes a very short (10th of a second) blink about every two seconds.  If you delete that key, and have autorun disabled, the entire problem is resolved.  I am appalled that absolutely no one at Dell technical support knew the answers to our questions.  Neither of these issues is documented anywhere.  It seems like Dell technical support does not have the ability to say "I don't know".  Instead of researching the issue, they make up a factitious answer.  The response I got from them on the phone was: "You have a high-end machine and in those XPS machines the hard drive light is really an input/output monitor, so it is blinking not only from hard drive activity but from network activity."  That was just a made up answer, it has no basis behind it.  As I had mentioned in a previous post to this discussion thread, if this was such a desirable feature, how come Dell does not tell the customers about how "wonderful" it is?  How come it is not documented anywhere?  We now know the answer, and we had to figure it out by trial and error.  For those of you who still have the eternal blinking problem, there is more than one way to disable the Autorun feature.   

Again, not your same situation but I wanted to see what would happen

Dont know exactly what you wanted me to try from that...but I searched in regedit for that registry entry and came across no entry as "DSentry" ....did you want me to try turning off autorun?
