ഒരു പഴയ കഥ An Old Story

ഇതു കുറേക്കാലം മുന്പു നടന്നതാണ്. എന്നാലും എഴുതാം.

Problem Reported :- Windows98 installation got corrupt and unable to reinstall Windows on the computer. Many people tried and failed. All of them suggested replacing the motherboard.

Configuration: AMD K6-2 CPU on a Via chipset Motherboard, 64MB SDRAM, 8.4GB Seagate HDD, Samtron 55E Monitor.

No visible faults were found on the motherboard. POST takes place properly. So it is clear that the problem is not a very serious one. Partitioned and formatted the hard disk. It worked fine. Started loading Windows98 from the CD. Installation progressed to around 60% and then it showed a message 'unable to read from the installation package' and then the installation terminated.
As the installation CD was original one there was no doubt about it. Still tried to copy it to another system and it copied without any problem. Then copied it on the problem system using Xcopy command of DOS. That too worked fine.
Again tried the installtion. This time the installation completed but after restarting Windows did not come up. It showed the Windows boot screen and then hanged.
Tried to restart in Safe mode. That too did not work. Again tried the installation. This time after restarting Windows logon screen came up but after logging on the dreaded Blue Screen appeared.
From all these it is clear that the real problem is with the memory. Just to rule out the possiblity of any HDD fault, tried it on another system. It worked fine. Checked the RAM also on another system. That too worked fine. Tried other combinations with the IDE cables also. That too was fine.
The final doubt fell on the L2 cache on the Motherboard. Disabled it from Setup and tried to reinstall Windows. Everything worked fine this time. It just seemed a bit slow.
After this system worked fine for more than three years without any problem after which they exchanged it for a new one.
