The system configuration is very low and the OS and software used are all very latest. Like 486 has 2000 or o/s installed in 98s, PI, 166 MHz speed and RAM capacity is less.

· RAM is very less.

· There is a lot of software installed in the hard disk which is also loaded at startup.

· There are many antivirus software loaded in the system which slows down the booting of the system.

· There are data areas located in the hard disk, which takes a long time for the system to read. Defrag it by tools, this also brings data in a queue and increases system speed.

· There is a virus in the system and try to clean it.

· The CD drive in the system is not able to read the CD properly, which will slow down the booting. Or the system will halt for some time.

· Os is not installed properly. Install the os speed other software again by doing HDD format.

· There are may bad sectors in the hard disk any many system files have been damage?

· Processor and board are working but speed is slow due to mismatching.

· There are many desktop themes, and screen sever etc. installed in the system. There are also a lot of softwares installed in startup.

· CPU cooler is not working due to which the processor can become hot and slow down.

· RAM is partially bad and try to replace it.

44. At the time of system boot, scandisk itself start running and demands to run surface scan in hard disk.

· Scandisk itself runs when the system improper shutdown has been done but even after proper shutdown, if the system suggests hard disk for surface scan before booting, it means that hard disk has become bad sectors. In such a situation, after taking a backup of the data from the hard disk, make the hard disk a low level format, this will fix the bad sectors, now install windows and other software on it again. When bad sectors arrive, if they are not fixed, then their number increases and hard disk may crash.

45. The following message comes when the system is booted from windows.

This message is received when the display card installed in the system is not configured, so reinstall the display card from its driver and restart the system. Also set the resolution and color palette of the monitor.

· There is dry solder in any of the components of the motherboard.

· The regulator device of the motherboard is defective or dry solder.

· If there are too many jumpers on the motherboard, then the jumper setting can also be wrong, especially RP is getting less volt.

· All the outputs from SMPS are not being received regularly, sometimes they are received and sometimes they are being missed.

· Try using another RAM. Problem if there is dry solder or any short circuit in the jumper setting and motherboard which is getting fixed sometimes, in such a situation also checks once if the motherboard is not short from the cabinet. Otherwise it is a difficult task to find dry solder. Soldering all the big components especially power regulator and crystals once again do not resolder the VLSI chip.
