My Compaq Presario CQ50-142US will not boot up

I get a black screen and it says it can not find my hard drive. I have been screwing around with it all day and now all I have is a black screen and a blinking white horizontal line in the top left corner.

SOURCE: computer displays black screen with blinking cursor

Its seems its not booting correctly. Just Insert Windows CD and fix the windows. Another solution is to press (I think) F1 or F11 or F12 (depending on the model) when booting the machine. It will take you to recovery mode. Use it to restore the boot section ONLY.

SOURCE: black screen, blinking cursor in top left hand corner

Could be a number of issues, incl unseated processor or a faulty hard drive. First off I would remove mains & battery, remove covers from underneath and reseat any memory or processors you can find - by reseat I mean just take out and put back.If this fails, I would look to price up a new hard drive before condemning the machine.

SOURCE: blinking white dash during boot.

Something has messed with your MBR, master boot record, which is a small sector at the beginning of your first hard drive which tells the bios which partition to boot. You'll have to use your xp or vista's installation disc to repair the system.( Choose; repair this installation of windows when prompted )
While you are in the bios check under the boot section the order of your boot devices. If you have more than 1 HD check that the one containing your OS is first.

SOURCE: MY COMPAQ PRESARIO NOTEBOOK CQ50 100EM - DOES NOT

The issue might be with the hard drive. I recommend you to test the hard drive.
If the hard drive test fails, then it is confirmed that the issue is with the hard drive of your notebook.

MY cOMPAQ pRESARIO CQ60 fell and cant complete boot


Most likely in this case, the damage is to the hard drive or its connection to the motherboard. The CQ series though has a three point screw attachment for the hard drive so Im more inclined to think that the shock of the landing has damaged the read/write head on the hard drive. If you happen to have another hard drive for a laptop, try installing a new drive and run the installation disc and see if it will complete and boot completely....if it will then the problem was the old drive.

Try another hard drive in the system, sounds like the drive is going bad, then after replacing the hard drive, then go ahead and recover the system. Bad sectors on a hard drive can make it where it won't restore.

If you can get your hands on a windows boot disk, then you can try to format the hard drive, wiping it out and installing it can fix that problem as well.

The machine is trying to boot from a device either cd/dvd drive or the hard drive try taking out disks that maybe inside the drive otherwise your hard drive may be at fault. You could try downloading on another computer a hard drive test and burn it to cd and try booting off that to determine if the hard drive is faulty

Turn on goes to black screen


Can you access F10 bios - if you can access bios you have a hard disc failure - remove you hard drive - boot the system without the hdd and see if the pixie boot boot goes through - seen it before - your hdd is unservicable.

Go into Setup of the BIOS while booting up and check to see if the computer is seeing the hard drive, if it is not replace the hard drive and reload the O.S. if it does see the hard drive try booting in the safe mode or the last known good configuration mode. BPCS

Presario 1693 issue


Go to (CMOS) Setup at boot and "detect" your new hard drive.  Then boot from your operating system CD and prepare (partition, format) your new hard drive and let your OS install.

Replace hard drive on Compaq presario 2190US


NO its a software crash use the installation disk you said you used......go through the blue screen allowing windows to boot up from that disc let it go right to the end and press "R" for the console (the dos line ) when there enter ....     chkdsk /p

Let Windows fix any problems. When finished remove the disc and I bet it will open windows for you.  Please come back and tell me how did you do because most people that I helped with this problem just run but you know old saying "what goes around comes around"
