Are you facing sudden system crash problems including ugly blue screens without showing any error message. If this is the case then you may have the problem with your RAM or DIMM memory.

Although, Memory chips are tested by manufacturers but memory chips are very sensitive and can be crashed by touching it by hand. There are many reason for memory to be faulty:

  • Electrostatic charges or ESD shock from improper handling
  • Frequent AC power surges
  • Dirty and Dusty PC Box internally
  • Operating in very humid and tropical environment
  • Metal contacts between the memory module and the motherboard DIMM memory slot
  • Heat dissipation from other components may cause gradual thermal damage.

Bad memory indication

This are the frequent indicators of faulty memory:

  • Failure to boot and accompanied by repeated long beeps.
  • Random system crashes or blue screens during the running of NT,2000 or XP.
  • Blue screens during the install procedure of Windows NT,2000 and XP.
  • Crashes during usage of memory intensive software such as Photoshop,3D Games,Benchmarking utilities .. etc.
  • Distorted Video graphics on the monitor screen

How to check bad memory

There are three software that i have checked are available in the market to check faulty memory.
