Common Dell Error Codes
Dell systems display specific diagnostic codes and Windows errors when a hard drive or operating system fails. If you see any of these on your Dell, bring it to us for fast diagnosis and repair.
No Boot Device Found
Your Dell can't detect a bootable drive — often caused by a failed hard drive, loose cable, or corrupted boot sector.
INACCESSIBLE_BOOT_DEVICE
A Windows blue screen error (BSOD) meaning the OS can't access the system drive. Common after updates or drive failure.
ePSA Error 2000-0141
Dell's built-in diagnostics detected that no hard drive is present — the drive may have failed or disconnected.
ePSA Error 2000-0142
Dell diagnostics found a hard drive self-test failure — usually indicates the drive is failing or has failed.
CRITICAL_PROCESS_DIED
A critical Windows process stopped unexpectedly — often caused by corrupted system files or a failing storage drive.
UNMOUNTABLE_BOOT_VOLUME
Windows can't mount the boot partition. Typically caused by file system corruption or physical drive damage.
Operating System Not Found
The BIOS completed POST but can't find an OS to load — the drive may be dead, disconnected, or wiped.
KERNEL_DATA_INPAGE_ERROR
Windows couldn't read data from the drive into memory — a strong indicator of physical hard drive failure.
S.M.A.R.T. Failure Predicted
Dell's pre-boot check detected the drive's self-monitoring system reporting imminent failure. Back up immediately.
Automatic Repair Loop
Windows keeps restarting into repair mode without fixing the problem — often caused by corrupted system files or a dying drive.
Alert! CPU Fan Failure / ePSA 2000-0511
Dell's POST or ePSA diagnostics detected the CPU fan isn't spinning or is running below the expected RPM. The fan may be clogged with dust, failing, or disconnected.
Seeing one of these errors? Don't keep restarting — continued use of a failing drive can make data recovery harder or impossible. Call us at 703.635.4265 or schedule a repair for fast diagnosis.
Daryl replaced the hard drive on my wife's laptop, and the entire process, including scheduling, was fast, efficient, and at a very fair price. His communication was timely and clear, and the repair was done right. Highly recommended!Read full review
I purchased a new laptop and Daryl transferred all data from my old laptop. He also fixed the WiFi extender and disconnected the old laptop from our home WiFi network. He always explains what he's doing which helps me understand my laptop and WiFi. I highly recommend Mt. Vernon Computers.Read full review
My teenager did not properly back up her laptop. So, when it totally crashed she lost access to her English final and all her junior year school files. In a panic we called Daryl on a Sat morning. He was able to retrieve all her files and make them available for use on either a PC or Mac. We have both and were not sure which computer would be used to finish up the school year. We had the all her files by 6pm that same Sat. You will not go wrong with Daryl. His prices are reasonable and we found him knowledgeable and honest. We will be using Daryl again for any future problems.Read full review
