Generally when this happens it can be a number of things. First of all try swapping over the RAM to a different dimm slot. I had that problem which took me hours to work out but once i did that then it all came up and worked again

Lookbook will not power on


A computer that won't start can be both alarming and infuriating, especially if you're on a deadline or you haven't been backing up all your data (like we all tend to do). Don't panic, though-this problem often has a simple solution.

1.If your desktop computer does nothing at all when you try to start it, first check that the power cable is securely plugged in at the back of the computer as well as into a working power outlet. It's amazing how often this is the case.
2.If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer.
3.If the computer is plugged into a surge protector, see if the surge protector has a reset switch that you can push. (If it doesn't have a reset switch and the problem is with the surge protector, it will need to be replaced.) Try plugging a lamp or other device into one of the surge protector's outlets to make sure it's working.
4.If you can hear the computer's fan or hard-disk drive, or if you can see indicator lights on the main unit but the monitor stays dark, make sure that the monitor is connected to a working power source, that it's turned on and that it's securely connected to the computer via the video cable.
5.If the monitor and computer have power but the computer displays a "Non-system disk or disk error" message, check to make sure you didn't leave a disk in the A: drive. If you did, eject it and restart the computer.
6.If the operating system still won't start even though the computer and monitor have power, try restarting with a Windows CD-ROM in the CD-ROM drive or, if you've got a Macintosh, with a Mac OS disc in the CD-ROM drive. (You can start a Mac from the CDROM drive by holding down the C key while starting up.)
7.If the operating system then starts, your problem is probably with the startup hard drive or with the operating system installed on it. If you can't fix the drive, you'll have to replace it. (See also How to Fix Bad Sectors on a Hard Disk and How to Recover Lost Files.)

My desktop computer won't turn on it just keeps blinking orange.


A computer that won't start can be both alarming and infuriating, especially if you're on a deadline or you haven't been backing up all your data (like we all tend to do). Don't panic, though-this problem often has a simple solution.

1. If your desktop computer does nothing at all when you try to start it, first check that the power cable is securely plugged in at the back of the computer as well as into a working power outlet. It's amazing how often this is the case.

2. If you're starting from a button on the keyboard, make sure the keyboard is connected to the computer.

3. If the computer is plugged into a surge protector, see if the surge protector has a reset switch that you can push. (If it doesn't have a reset switch and the problem is with the surge protector, it will need to be replaced.) Try plugging a lamp or other device into one of the surge protector's outlets to make sure it's working.

4. If you can hear the computer's fan or hard-disk drive, or if you can see indicator lights on the main unit but the monitor stays dark, make sure that the monitor is connected to a working power source, that it's turned on and that it's securely connected to the computer via the video cable.

5. If the monitor and computer have power but the computer displays a "Non-system disk or disk error" message, check to make sure you didn't leave a disk in the A: drive. If you did, eject it and restart the computer.

6. If the operating system still won't start even though the computer and monitor have power, try restarting with a Windows CD-ROM in the CD-ROM drive or, if you've got a Macintosh, with a Mac OS disc in the CD-ROM drive. (You can start a Mac from the CDROM drive by holding down the C key while starting up.)

7. If the operating system then starts, your problem is probably with the startup hard drive or with the operating system installed on it. If you can't fix the drive, you'll have to replace it.

You can check it here as well:
The minute your computer's hard disk starts to act flaky, make sure you have an up-to-date backup. Then you can do some simple diagnostics and repairs. Both Windows and Mac OS come with built-in hard-disk utility software that scans your hard disk for errors and attempts to fix them.

1. Double-click on My Computer to open the My Computer window.
2. Select the disk that you want to diagnose and repair.
3. Choose Properties from the File menu. You should see the Properties window for the drive that you selected.
4. Choose the Tools tab.
5. Click the Check Now button under Error Checking Status.
6. Depending on your version of Windows, choose either "Thorough" or "Scan for and Attempt Recovery of Bad Sectors."

7. Click on Start.

There is no display in the monitor when power is on. how to repam


1. Check with the Power supply:

2. Check with the Hard Disk:
Most probably, your hard disk doesn't work. First check the IDE or SATA cable connecting your motherboard and the HDD. Detach first cable wires and then reconnect it. Try to put it on. IF still it doesn't try to replace a cable (IDE or SATA). If it still don't work with that. Have another computer and slave the HDD from the PC not displayed and check disk by running a DOS Command prompt by typing "cmd" then type "chkdsk" to see if the HDD works.

3. If the hard disk is ok, try to use another computer replace it with the Power Supply from the computer that doesn't display. When it is connected, switch on press "del" or "F1" or "F2" to log to CMOS. Try to look for "Health PC" section and try to see if the battery is ok. One way to determine the power is ok is looking at power input to 12 v to 12.6v. If it's lower than 12v your power supply must be replaced.

Try one of these steps.

Trubleshoot Motherboard


More than 70% of all computer problems are related to cabling and connections. Ensure all cables are connected and connected firmly. IDE and floppy ribbon cables and power cables can often go loose. Ensure microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to vibration.
System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on. PROBABLE CAUSE DIAGNOSIS SOLUTION
Power cable is unplugged. Visually inspect power cable. Make sure power cable is securely plugged in.
Defective power cable. Visual inspection, try another cable. Replace cable.
Power supply failure. Power cable and wall socket are OK, but system is still dead. Contact technical support
Faulty wall outlet;circuit breaker or fuse blown. Plug device into socket know to work and test. Use different socket, repair outlet, reset circuit breaker or replace fuse.



System inoperative. Keyboard lights are on, power indicator lights are lit, and hard drive is spinning. PROBABLE CAUSE DIAGNOSIS SOLUTION
Expansion card is partially dislodged from expansion slot on the motherboard. Turn off computer. Take cover off system unit.
Check all expansion cards to ensure they are securely seated in slots. Using even pressure on both ends of the expansion card, press down firmly on expansion card.
Defective floppy disk drive or tape drive. Turn system off.
Disconnect the cables from one of the floppy drives. Turn on the system, check to see if the keyboard operates normally. Repeat until you have located defective unit. Contact Technical Support.

A number of causes could be behind this. Use a file by file backup instead of an image backup to backup the Hard Disk. Back up any salvageable data. Then do a low level format, partition, and high level format of the hard drive( see Hard Disk section of your manual for instructions). Re-install all saved data when completed.



Disk formatted on IBM PS/2 will not operate with this system. PROBABLE CAUSE DIAGNOSIS SOLUTION
The IBM PS/2 uses a different format than other computers. IBM PS/2 disk format will not work in an AT type computer. Format disk in the AT type computer insert disk into the IBM PS/2 and copy the files you wish.



After install an expansion card (network card, tape drive card, etc.) the system no longer works properly. PROBABLE CAUSE DIAGNOSIS SOLUTION
No power to monitor. All or part of the system may be inoperable. The new card may work but a mouse or COM port may not work. Change the interrupt or RAM address on the new expansion card. See the documentation that came with the new card in order to change pin settings. many expansion devices come with proprietary software that will assist you in doing this.



Screen message says "Invalid Configuration" or "CMOS Failure." PROBABLE CAUSE DIAGNOSIS SOLUTION
Incorrect information entered into the configuration (setup) program. Check the configuration program. Replace any incorrect information. Review system's equipment. Make sure correct information is in setup.
