Hello,

My CPU comprises of Intel core 2 duo@1.8 GHZ, Intel D945GCL motherboard , 2GB DDR2 RAM , Nvidia 8400 GE force. A few days back,I had got a Blue screen error saying that there was some hardware changes made although I didn't do any. The main problem is that ,this morning my system was running unusually slow and it took about 2.5 minutes(normal time is around 1 minute) for booting windows XP professional SP2.

The windows start up music comes along with some noise. When I'm on the desktop, I can hear a periodic noise that comes from both cpu and speakers. Also, the LED indicator at the front of cpu cabinet would periodically flash a dim light when there is noise. This problem had occured earlier and the technician whom I had called then was able to solve the problem. He just blew off the dust from RAM and also he inserted the cable that connects hard disk to motherboard, to a different slot on the motherboard. I just did the same today and everything is back to normal.

I want to know what is actually causing this problem and whether it is severe or not. Also how does it become alright when the hard disk cable is moved to different slot on the motherboard?

Thanks

Could be a bad SATA cable, not maintaining a good connection to the motherboard. It is not uncommon. Or, it might be your PSU is going bad.

Well i have a few questions.

First question, the noises your hearing. What does it sound like? grinding, scratching, ect.

Second, how old is the hard drive, the cables connected to it and the motherboard?


Somehow dont think the cpu making any noise scene there no moving part on it (except for the fan on top of it). for led light, Are you meaning the Light that on the front of the computer that can adjust in brightness?

If so then that light would be for how active the HDD is.

This part i can not really figure out. maybe a bios issue.

Hi, thanks for the replies. I used to hear periodic scratching sound from the speakers and periodic beep sound from the cpu.
Coming to the LED, I meant the one which flahes, when there is some processing going on in the cpu.
Also does this mean any critical damage to the hard disk .
The whole computer is about 3 years old.
