Please help me.. I have to know weather it is hard disc problem or my system problem i have changed my hard disc before 5months only

Waiting for your valuable replies

try to change Power Cable of HDD and/or SATA Cable of HDD

the other thing can be - ur PC looks too old so may be ur motherboard is feeling tired and needs to get retired

yeh try the power and sata cable, ur power unit might be the culprit, for providing low power. check that too
