After using our computer for a couple of months we observe that it has slowed down. This is due to the way windows installs your programs. When you install a program windows look for a satisfying space to install it on your HardDisk. However it may not be installing in the correct order so that it's loaded quickly!
Therefore you'll need to defragment your HardDisk (May take you around 1 Hour)
How to? Open 'My Computer' / Go to the partition in which your Operating system is installed e.g Windows Xp/Vista/7 Right-click on it/ properties/tools/defragment now Go to analyze disc & then defragment HardDisk
There are different possibilities for system hang up. I want you to find it your self from following my simple instruction.
1. (when computer is turn on) Check temperature... overheating can cause system to hang up, it can cause the system to reboot, it can cause the fatal error message and turns your screen to blue. Overheating is cause by exhaust fan or blower not working. Find this blower or exhaust fan on top of the processor, as built in fan in your video card, attached on your power supply and on the casing of your computer. Replace non working fan or blower.
2. Check video card...faulty video card can cause your system to hang up. It can cause also your system to go on blank screen. Most common problem is loosen connection of video card from the motherboard. Disconnect and reseat the video card properly. Inspect the fan, if not working then video card will overheat and system fail. If you previously see moving colors in your screen especially small boxes, or discoloration and screen going black and white then it means video card is already failing. You will need to replace it.
3. Check for hardware failure. keyboard, mouse lan card can cause your system to halt and hang. You will need to disconnect this first when booting and see if by removing this hardware will complete the system to boot up to operating system. Replace faulty one.
4. Harddisk failure. when computer reset or will not boot up completely then hard disk usually cause this problem. Initial remedy is to reseat its connection sata, ide or power supply connector. If you hear ticking sound in the harddisk or excessive vibration then it will need replacement.
5. Operating system corrupted. this can cause your computer not to boot up properly and hang the system. Reformat and reinstallation of operating system is required.
6. Power supply failure. you need to check the output voltage. dropping of voltage can be cause bi leaking capacitor in the power supply unit. replace it with exact value. Voltage should read +12VDC for yellow, +5VDC for red. and should be stable even with load.
Since you say, you have a new hard disk I am assuming you have not formatted it or there is an operation system on it. If that is the case, power on your laptop. As soon as you does this start pressing F2 (intermittently = press, then release) and keep on doing it till you get into the bios screen. Once you are there change the boot sequence to CD drive first (It will be on Harddisk at present) Once you have made the first boot device to CD drive, open the CD drive and put an operating system CD like XP, Vista or Windows 7. Save and exit from the bios screen. Restart the computer. It will say press any key to boot from CD drive. Press any key. The system will come to the operating system installation screen. Install the operating system. If in doubt get assistance in getting someone to install the operating system. Without the operating sytem or a bootable CD once the Bios hands it over to the system there is nothing to display and you do not see anything on the screen. It looks like that is your problem. Good luck.
If it starts to load the operating system and then the display goes black then chances are that the dispay/video drivers are corrupt.
Boot the machine into safe mode by restarting the computer and repeatedly press the F8 key as it starts. This should bring up a sub menu with safe mode at the top. Use the cursor keys to highlight safe mode and press enter. You will see white boot information scroll up the screen, be patient and wait for it to load up. Click on your account and you will see a message about system restore. You don't want to use system restore so click on yes to work in safe mode.
Right click on My Computer/Computer and click on manage from the list. Then select Device Manager.
Look in the list for display adapters and click on the + or > next to to expand the list. Right click on the display adapter and select uninstall.
Restart the computer and it should load up the operating system and reinstall the drivers for the display.
you need to select ur harddisk as the first bootable device., that option is in BIOS settings. When switch on the system before loading OS press F2 to get the BIOS settings and select boot option in the menu and select your harddisk as the first bootable device. Restart the system now. If the same error is displayed your harddisk data cable may be failed or your harddisk may be corrupted...
Just try resetting the BIOS and check if it works.
You need to access BIOS screen and most of the computers has F% key is assigned for Loading the Dedault Settings. After F5 key you need to press the F10 key to save the settings and exit from the BIOS.
MY PACKARD BELL PIV HAS N1996 MOTHER BOARD I cant see any display on my screen when i turn on my computer. But it looks it has read all the information from harddisk and loaded the operating system. but on screen i cant see any raster i.e. display.
