Hi guys ,
need your help badly. Recently my Case fan had started making a lot of noise. so i had disconnected it cleaned it and plugged it back into the motherboard again
. However after i did this the Pc started normally once or twice but after that as soon as i switch on the power supply,a siren like noise
starts coming from the pc internal speakers
. what could be the problem?
also i had recently i had added a 512 mb ram chip to my system but every thing seemed to be fine till this fan issue.
I have checked that the ram is inserted properly.
What could be the problem
