The CMOS is what stores the settings for your computer.
You might have a faulty PSU then
Signs of a faulty PSU or Memory issue- http://wiki.answers.com/Q/What_are_f...y_power_supply
1) The power reading (battery monitor) changes frequently/fluctuates
2) The computer shuts down through loss of power when it seems to be on full power
3) the power cable is damaged, very old or has been faulty in the past
It takes some experience to know when this type of failure is power related and not caused by the memory. One clue is the repeatability of the problem. If the parity check message (or other problem) appears frequently and identifies the same memory location each time, I would suspect that defective memory is the problem. However, if the problem seems random, or if the memory location the error message cites as having failed seems random, I would suspect improper power as the culprit. The following is a list of PC problems that often are related to the power supply:
- Any power-on or system startup failures or lockups.
- Spontaneous rebooting or intermittent lockups during normal operation.
- Intermittent parity check or other memory-type errors.
- Hard disk and fan simultaneously failing to spin (no +12v).
- Overheating due to fan failure.
- Small brownouts cause the system to reset.
- Electric shocks felt on the system case or connectors.
- Slight static discharges disrupt system operation.
In fact, just about any intermittent system problem can be caused by the power supply. I always suspect the supply when flaky system operation is a symptom. Of course, the following fairly obvious symptoms point right to the power supply as a possible cause:
- System is completely dead (no fan, no cursor)
- Blown circuit breakers
