Constant beeping and...mouse scrolling issue?

So I have been having an intermittent problem the past few days. on rare occasions, the scroll function on my wireless mouse will seem to stop working. I can start to scroll down a webpage and it will bounce right back to the top of the page. Shortly thereafter, the laptop (R1) starts beeping nonstop (no codes, just constant beeping) forcing me to shut it off. It usually restarts but sometimes seems starts the beeping again during startup (a second restart seems to fix this issue). The OS has been recently reinstalled, no viruses/malware/etc (bitdefender, spybot and malwarebytes all give the PC a clean bill of health). BIOS is A08 and the diagnostic tool in the bios give a pass to every system component, however during the memory test, the constant beeping will happen every time. I ran memtest86 on it and everything seemed fine. Ran the online diagnostic tool from the dell support sight and everything seemed fine. On a couple of occasions, the beeping has stopped when I removed the usb dongle for the mouse (though similar issues have shown up with the trackpad as well). The laptop is about 4 months out of it's year warranty.

Any thoughts on what it might be? What tests I should do? I have a different set of RAM I can put in but every test shows the RAM in the laptop to be fine.

 

Anything you can recall that would trigger the beeps? Does it beep in any sort of sequence?

Please post your specs

 

Nothing that would seem to trigger the beeps. Sometimes the mouse issue shows up and then a couple minutes later the beeping starts. Any particular specs you are looking for? Nothing was changed recently hardware wise that would seem to have started this.

It's an m14xR1
500GB Samsung 830 SSD
Nvidia 555M 1.5 GB
i7-2670QM
BIOS: A08
8Gb RAM (two 4Gb sticks)

The only modifications I have made to the laptop are the SSD HD and doubled the RAM (it originally came with 4Gb of ram total). Both modifications were done well back in 2012 and I have had no issues with them.

 

Based on the information from this thread with a similar issue, I took, "the CMOS battery out, the battery and the AC Adapter and press the power button for 1 minute". I put everything back except the battery and plugged in the ac adapter. Started the laptop and got a blank screen with 5 beeps which, per this link, I treated as a "CMOS battery failure" and followed the instructions to fix it (The CMOS battery is a 3 volt battery that tested as having 3.08 volts when it was out of the laptop). During the boot up process found at the link given to fix the "CMOS battery failure", I got the following screen with a series of beeps...



The beep code was 1-3-1 which, per a post at this link, means, "Memory/RAM Not Properly Identified or Used". I let the BIOS diagnostic tool run it's tests and everything passed. After that rebooted, windows came up but windows explorer would occasionally stop working and have to restart. When I attempted to shut down I got the following error:



After the laptop was shutdown, I replaced the RAM with the original RAM that came with the PC (which had never given any problems and was only in the laptop for a couple months). When starting the laptop while pressing the function key (again, no battery but AC adapter plugged in), The same errors would occur with the system tests all passing. When the battery was put back in, the only difference was that the no battery error screen (and 1-3-1 beeps) didn't show up.

My plan is to run memtest through the night and I might pop in the original hard drive and reimage it with a fresh copy of windows tomorrow.

 

If you already had a fresh install of Windows and that didn't fix your problem, it sounds like it could be a driver issue or a hardware issue. Have you tried booting into safe mode to see how long the system can run without any additional drivers or background processes running.

I know you have BIOS A08, but have you done a BIOS reset? What are your memory profiles set at? Make sure any overclock is disabled in BIOS.

 

Well, I reflashed the bios and reimaged the HD with a new Windows installation. 9 passes with memtest and no errors. the pre-boot system test still shows everything in working order. The only indication of any issue I get is when I have the battery out and the PC's only power source is the AC adaptor. In this state, I start with the function + power button to trigger the pre-boot system test and I get a notification that there is no battery install along with the 1-3-1 beep code. After I acknowledge that notification, everything tests fine.

 

So, after flashing the BIOS and reimaging the SSD, everything seemed to be good...for a few days. Yesterday afternoon I got a BSOD.

After researching the code given for the BSOD(IRQL_NOT_LESS_OR_EQUAL - ntoskrnl.exe+75c00), I turned on driver verifier (for all but Microsoft drivers) and then applied this memtest which functions inside the OS. After letting it run overnight, I got the following error screen:



I swapped back the original 4 GB of RAM into the laptop. When I turned the laptop on, when it got to the Windows logo screen, the laptop started beeping constantly (no code). Restarted and went into BIOS system diagnostics (occasional beeping but with no code throughout (bursts of about 30-50 beeps)). Now when I try to start the PC it seems to freeze on the logo screen before the logo appears (it just says "Starting Windows" and beeps for a long while (counted 79 beeps this last time) before the logo finally appears and it moves to the login screen. When in windows the mouse function (via trackpad) is inconsistent. Scrolling doesn't really work and even selecting anything below the top entry in a list of files only pulls up the top entry.

Any thoughts?
