COMPUTER SCREEN IS BLANK

Computer Screen is Blank



Problem - The Computer Screen is Blank. You start your computer and the monitor remains blank, although the monitor's power light is on.

Possible Causes: You have a hardware problem or a BIOS setup problem. Your computer hardware has not been installed correctly, your motherboard's jumpers are set incorrectly, your BIOS settings are not correct, or your computer or peripherals have been shorted out and/or have some other mechanical problem.



Remedies. The remedies below should be performed in order. Turn off the computer after each step. Never work inside the computer case with the power turned on.



1. Check and make sure all cables are firmly attached to the back of the computer and to all external devices. Retry.



2. Remove the case cover from the computer. Make sure all cables (hard drive, power cables, other disk cables) inside the computer are firmly attached.

Press down on all ISA and PCI cards and make sure they are firmly seated. Make sure your DRAM memory cards are firmly seated. Feel the top of the CPU and make sure it is not hot (warm is OK). Retry.



3. This step is only for newly built computers that have not successfully booted. Get out your motherboard manual, or download one from the manufacturer's site, and go over all your motherboard jumper settings.

Set the jumpers in the most conservative position. Review all your accessory wire connections (keyboard lock, hard drive access light, etc.) and make sure the connectors to the motherboard are facing the same direction. Retry.



4. Turn the computer back on with the case off. Verify that your CPU and power supply fan are running. If either one is not running you have a problem. If the power supply fan is not running replace the power supply (make sure the power connectors are correctly attached to the motherboard). Make sure the CPU fan is connected to power on the motherboard. If it is correctly connected and still doesn't run, replace it. Retry.



5. Unplug your computer. Remove all PCI and ISA cards. Reinstall the video card and disconnect the hard drive cable. Plug in the keyboard, video cable, and power cable. Restart your computer. If this worked, go to Step 6. If your DOS screen doesn't come up at this point try the following ideas.



a. Closely examine your motherboard and make sure it is not making contact with the computer case, which will short it.

b. Your video card, video cable, or monitor may be malfunctioning. Borrow a video card, cable and monitor, retry.

c. Remove and reinstall your DRAM. If your computer can not find system memory it will not POST.

d. Remove the CPU and reinstall it.

e. Follow your motherboard manual's instructions for resetting your BIOS to its default configuration.



If your computer still will not boot into a DOS screen, seek professional help.



6. If you now have a DOS screen on your monitor, attach your hard drive cable and reboot. Make sure the hard drive is correctly set up in the BIOS. Press the Delete key during the POST memory check to enter the BIOS. If your hard drive doesn't work, you have incorrectly attached the drive ribbon cable or power cable. See our article Installing a Second Hard Drive for the correct procedures for installing the hard drive ribbon cable.



7. Add your other PCI and ISA cards back into the computer one at a time. Reboot after each card is installed to make sure the new card isn't causing a problem.

COMPUTER VIRUS PROBLEM



Problem: Virus causes computer crash at, "Verifying memory pool data." Hi, my computer recently crashed (Melissa virus?) and now I can not get it past... verifying pool data.. I cant type any thing. What should I do?? malicious







ADMIN ANSWER. Boot your computer with a Windows Startup Disk (make sure the disk is write protected) or from the Windows CD-ROM. Then you should try to reload Windows to the same directory it was originally installed in. If you successfully reload Windows you should then go online and visit our Free Online Virus Scan page and run the virus checker to clean the virus from your system.



If you can't install Windows to its current directory then you have to load Windows to a new directory, or format your hard drive and reinstall Windows.



See reloading Windows



Resolving Windows Fatal Exception Errors. First -- Please do not format your hard drive. Formatting the hard drive and reloading Windows is one of the last steps you should take, as it may not solve your problem.



Fatal Exception Errors are usually caused by deletion or corruption of Windows system files, computer viruses, out-of-date hardware drivers, or ill-behaved software programs. Some errors are well documented but most are not.



It would be easier to determine what is causing your problem if you could remember what program or driver you loaded that caused these errors to occur.



As this is not always possible to do, I suggest you do the following in the order presented. Determine if the error has corrected been by rebooting and using your computer before going to the next step.



1. Disable all anti virus programs from starting up automatically -- do not disable firewall programs. Visit Free Online Virus Scan page and run the virus checker to clean any new computer viruses from your system.



2. Visit your computer and other component manufacturers, and make sure you have the most recent Windows drivers for your video card, sound card, modem, printer, scanner, and for any other peripheral you use.



3. Upload the newest versions of your Internet browser and your mail programs.



4. If the problem is still not resolved, reload Windows into its current directory (do not format the hard drive). This should overwrite corrupt or missing system files.



5. The last thing you should do is format your hard drive and reload Windows. Please see the reloading windows page



After reloading Windows, load your drivers and software applications one at a time, and reboot after each is loaded. Use your computer after each driver or program is loaded, this should allow you to pinpoint any offending program/driver.

HARDDISK PROBLEMS AND SOLUTION

Problem: Can't access my crashed hard drive. I have 2 hard drives on my computer, a 2 Gig, that has Windows installed on it (C:) and a 10 Gig, for files and stuff (D:). They are two totally separate drives, not partitions.


Anyway, one day I booted up the computer and Windows wouldn't recognize the D: drive. The BIOS read it fine. I concluded that my hard drive crashed. Is there any way I can recover the data? I have tried to access the D: drive in DOS, but It doesn't want to read it for some unknown reason. Any help is appreciated.

I am downloading Norton Utilities, but if that doesn't work, I'm clueless. I have a bunch of floppies, so if I could get to the data I'd be all set. I am not rich enough to spend thousands of dollars to a disk recovery company. I have documents on that drive, which is why I want to try to recover them. I have a few floppies that I could put them on, if I could only get to the data. Do you have any ideas? Any help is appreciated.



ADMIN Answer: I suggest you visit your hard drive manufacturer's site and make sure the hard drive is set up correctly in your BIOS. Use the auto detect function in your BIOS, and if you are given several choices try different settings. Save the BIOS setting and exit by choosing (F10) and then Y. If the BIOS can set the drive up correctly you should be able to access the drive from DOS.

Does the read light come on when you try to access the drive or does the light stay lit all the time? The answer to these problems is to remove the computer case and make sure the drive cables are firmly attached.

Another possibility is that your drive has been formatted or damaged by a virus. Use a virus checker to make sure you don't have a destructive virus lurking on your system.

Try typing "dir" (don't type the quotes) at the DOS prompt to see if you can read the drive directory. If you can't read the drives' directory from DOS, either it is not correctly set up in the BIOS or your directory has been damaged. If Norton Utilities can't save your damaged drive, I know of no other way to save it.

I also suggest from now on you establish a back up routine to copy any file that is important to some kind of backup media: floppy disks, Zip drive, CD-ROM etc.



Problem: Recovering files from a crashed hard drive. My hard drive crashed. I have to send it to the factory to get it replaced. I can get into the files through a recovery disk using ms-dos. I have several files that were not backed up on disk.

I would like to transfer them to another computer with a cable pc/PC I tried copying them to a floppy. But whatever the problem with the hard drive it won't allow me to write to the floppy. What is the best way to do a DOS to Win98/computer to computer transfer? What software might I need to do it?



ADMIN Answer. A small shareware file, Zipft, will allow you to transfer files between your two computers with the purchase of a $10 null modem cable.

The only catch is, Zipft has to be running on both computers (which of course is the problem with any DOS file transfer system). So I hope you can at least copy this program to a floppy and run it in your computer with the messed up drive or this method will not work.

A null modem cable is a serial cable with serial connectors on both ends. Computer stores sometimes carry them, if you can't find one locally they are available off the Internet.

You plug the null modem cable into a serial port on both computers and then you have to use Zipft to transfer the files (a Word instruction file is included in the Zipft program, I suggest you read it thoroughly). The commercial programs Laplink and FastLynx also use a similar cabling technique , and may or may not be easier to use (any time you use DOS it requires some work) and will be much more expensive.

The second possibility I can think of is to remove the drive (if it is a desktop computer) and make it a slave drive in your second computer (a friend's computer could also be used). Files could then be copied directly from the damaged drive to your healthy hard drive, onto floppies, or to Internet drives.

Procedures for removing the hard drive and reinstalling it can be found in our article, Installing a Second Hard Drive .

Both solutions discussed are not for novices. If you feel uncomfortable about the procedures, get a friend or a computer repair shop to help you.



Problem: Can't use CD-ROM after setting up as slave to a hard drive. When I boot my computer I get the message (primary slave atapi -incompatible) and I will not have a CD-ROM



ADMIN Answer. You usually can't slave a CD-ROM drive to a hard drive. Set the CD-ROM up on your Secondary IDE channel (your other hard drive ribbon cable) either as a primary, or as a slave to another CD-ROM, Zip Disk, CD R/W, etc. Only slave hard drives to other hard drives.



Problem: How can I find out what hardware is installed inside my computer?



There is a free program called the Belarc Advisor, available for download at www.belarc.com. The Belarc Advisor will provide you all sorts of information on your motherboard, hard drives, RAM, video card, sound card, modem, etc

Windows Having Problems in Shutting Down Properly

Windows Having Problems in Shutting Down Properly


You may have come across the message 'Windows Shutting Down' instead of 'It is now safe to switch off you computer'. This is because a program has not unloaded itself properly that makes the computer insist to run a scandisk the next time you switch on. You need to close all the programs before your shut down your PC and if it is not done, the computer waits for the program to close. It may happen you get the message 'Do you want to shut this program down or wait' or you may not. When you don't get such a message it results in what we call the hanging of the operating system. The solution is not to install Direct X whenever you install a game. Most games have their version of Direct X that makes the files out of sync. Thus, install the latest version of Direct X and not the games version. You may need to also check USB devices, task scheduler, virus scanners, etc. and reinstall them if necessary. This will lead to correct installation and the problems with computer may reduce.
