Black Screen No Beep Replaced Ram Then No Beep Again

When yous kick upward your computer, you'll commonly exist greeted with some sort of snazzy audio or animation to show you things are starting up. Simply if your reckoner is giving you loud, ear-piercing, old-school beeps instead—and showing nothing but a black screen—something is wrong, and those beeps are trying to tell y'all what information technology is.

What Those Beeps Are Trying to Tell Y'all

Those beeps (which are known every bit POST codes, named for the PC'due south power-on cocky-test it performs at boot) are coming from a small speaker connected to your calculator's motherboard like the one shown to the correct, and they're designed to give you error codes when the screen can't. Think of them kind of similar morse lawmaking—you only need to take note of how many curt and long beeps at that place are, then look up the resulting code in your PC's manual. It won't tell yous exactly what you demand to practise, only information technology'll at least try to tell you what component is having problem, like the RAM, CPU, or video card.

Unfortunately, at that place's no standardized "beep dictionary" for these POST codes. Information technology depends heavily on who made the BIOS—the Basic Input-Output System that manages the boot process—and the manufacturer of your computer or motherboard can change the BIOS' default beep codes whenever they desire. And then, while there are some pages on the web that try to decode these beeps, you're best off looking in your computer's transmission. If y'all don't have the education booklet handy, head to the manufacturer's website (e.thousand. Dell, HP, MSI, and and then on), find the support page for your verbal model, and you should be able to download a manual in PDF form.

The Most Common Errors (and How to Fix Them)

While these Mail codes can sometimes mean a component has completely bitten the dust, there are a few common errors you tin set up merely past cracking your PC open and jiggling some things effectually.

If your manual says the beep code corresponds to a memory fault of some sort, then open up upwards your estimator and re-seat the RAM—that is, try removing each stick and re-inserting it, making sure information technology clicks into place. (This tin have a bit of force, especially on desktop computers, and then don't be agape to really button it in in that location.) If you aren't sure how to get into your PC or where the RAM is, we have repair guides for laptops and repair guides for desktop PCs of all stripes that volition evidence you lot the way.

If re-seating the RAM doesn't work, you tin besides try removing one of the sticks and seeing if the calculator boots with but one. If you can boot with one stick, then your other stick (or slot) may be bad. Thankfully, it'southward pretty easy to buy replacement RAM online—we even behave some in our parts store, so search for your specific laptop or desktop to observe a compatible replacement stick.

If your beep lawmaking points to a corrupted CMOS, on the other hand—the chip that stores your BIOS settings—y'all may need to reset those settings in order to boot back up. Immigration the CMOS shouldn't erase your data; instead, it'll only clear the settings governing the kick process. The steps for doing so can vary from machine to machine, and so check your laptop or motherboard manual—though it normally involves opening the computer, removing the money prison cell battery on the motherboard, then belongings down the power push for 10 seconds to discharge whatsoever electricity stored in the capacitors. Once you re-insert that coin jail cell battery, you should exist able to boot back up.

Finally, cheque for any other loose connections inside your PC. Has the CPU fan cable come loose? That could trigger a safety feature that prevents your computer from booting, and then jiggle it back into place. Is your graphics menu seated properly? Brand sure it hasn't come loose, and that all the requisite cables are plugged in snugly.

If you can't become your PC to boot with any of these fixes—or the beep code eliminates them every bit possibilities—a component may have failed entirely, which ways you'll demand to replace that function (or, in some cases, replace the unabridged motherboard). If your computer is still under warranty, contact the manufacturer. If non, cheque out our repair guides for laptops and repair guides for desktops to see what repairs might exist possible to do on your own. If zip else, you lot can use those guides to remove the difficult drive from your PC then y'all tin can migrate that data safely to a new computer.
