1) Hardware Conflict :
- Each H/W device communicates to other devices through an interrupt request channel (IRQ). It's unique for each device.
- eg.
- Keyboard usually uses IRQ 1
- Printer usually connects internally on IRQ 7.
- if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen.
- Gives Fatal Exception Error that indicates a serious H/W problem. Sometimes it may mean a part is damaged and will need replacing. It cause because of miss match of chip.
- Every motherboard is supplied with a range of chipset settings that are decided in the factory. To access these settings is to press the F2 or delete button during the first few seconds of a boot-up.
- Common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the computer's display.
- After a few weeks, the information on a hard disk drive starts to become fragmented. It is a good to do defragment the hard disk every week.Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.
- It caused by video card problems.
- To resolved it
- Go to
- Start-Settings-Control Panel-Display-Settings
- In the left look at the color settings on the left of that window. For most desktops, high color 16-bit depth is adequate.
