Hello!

I own a Dell Inspiron 4150 (yes, old laptop, but I love it). Yesterday I took it for a bike ride in my backpack and then when I came back later in the day I resumed work on a project. The computer worked fine until all of a sudden it gave me the Blue Screen O' Death. I did not catch the entire message but I think it was the DRIVER_IRQL_NOT_LESS_EQUAL_TO or whatever it is. So I powered it down, and when I tried turning it back on, it would turn on for about 5 seconds, the busy light would flash a few times then it would just shut off. The monitor stays black throughout the entire process.

So, I thought the RAM modules could be coming loose or something so I took a quick peek inside and everything seemed in order. So I undocked the laptop and tried turning it on again, but the same thing kept happening. So, out of frustration, I picked it up and shook it around like an insane moron (yes, I know it's not a good idea). But to my surprise the computer was able to start up (a couple times it froze at the menu where it asks you to press F2 to access the menu). So I decided I had to back up my files, but when I opened Explorer, the computer just locked up. No sound, or BSOD's, or anything. Simply frozen. So after force-shutting it down, I tried starting it up again. It had resumed doing the immediate shut-down.

Now I'm at a loss of what to do, because I can't back up my files or access anything without the computer locking up randomly!

Thank you in advance for your help (if you guys want to see a short video clip of what it does, I'll see if I can upload one. But basically I press the power button, the power light turns on, the busy light flashes for about 4 seconds, then everything just shuts off. The monitor doesn't even get a chance to go to the startup splash screen (it says blank the entire time).

A few focused checks will narrow this down quickly and protect the data reported. The symptoms you describe (intermittent POST, freezing after a shake, then BSODs that named DRIVER_IRQL_NOT_LESS_OR_EQUAL and PAGE_FAULT_IN_NONPAGED_AREA) fit two broad possibilities: an intermittent hardware fault (power jack, motherboard solder joint, or failing RAM) or a driver/OS corruption that surfaces when certain hardware (the PCMCIA USB2 card) is present. ’s note about recoverability is correct — treat the drive and files as the priority.

Practical next steps (in order):

  • Isolate power: remove battery and try AC only, and vice versa. Inspect the DC jack for looseness or damage. A flaky power connection can cause sudden shutdowns and corruption.
  • Minimal-boot test: remove all removable cards and peripherals (PCMCIA, PC cards, wireless cards) and try to get into BIOS/diagnostics. If the machine reaches Dell’s onboard diagnostics, run memory and basic board tests.
  • Memory verification: intermittent freezes and the PAGE_FAULT error strongly point to RAM problems; run a thorough memory test (MemTest86) from external media when you can get the machine to stay on.
  • If you can boot even briefly, create a read-only Live USB (Linux or recovery tool) to copy critical files off the drive before doing invasive fixes. This avoids further write activity that could worsen a failing disk.

About the BSOD codes: DRIVER_IRQL_NOT_LESS_OR_EQUAL usually signals a driver accessing memory it shouldn’t or a bad/overclocked/failed device driver/hardware. PAGE_FAULT_IN_NONPAGED_AREA indicates an invalid memory reference in a region that must remain resident — commonly bad RAM, bad drivers, or corrupted system files. Microsoft documentation on these checks is useful background: Bug Check 0xD1 (DRIVER_IRQL_NOT_LESS_OR_EQUAL) and .

Cautions: avoid shaking the laptop further — mechanical movement can make solder cracks worse. If the drive is valuable and the machine is unstable, prioritize a clean data copy (Live USB or external enclosure) or professional recovery.

Your motherboard could very well be bad. Your data is probably still recoverable, but you would need to take your hard drive out and hook it up as a secondary to a computer. Doing this would also aid in your hard drive diagnostic. If it still didn't work as a secondary drive, it is your hard drive. You could try switching the slots the RAM is in. If its an old laptop its probably not worth the repair (they are typically WAY to expensive to repair). Go to your local computer repairmen and get him to back up your data for you. Best buy will charge you 79 dollars, I'm not sure about anyone else.

Oh and on another note, I use a Usb2.0 PCMIA card. When the computer was able to start up a few minutes ago, I tried plugging the card in. The moment it was plugged in, the computer gives me the BSoD, this time claiming about PAGE_FAULT_IN_NONPAGED_AREA.

I don't know if these two problems are connected. I still can't start the computer up, with or without the card. :(
