When I turn my computer on it begins its startup up but only gets to the point where the logo for the motherboard is displayed on the monitor and stops there, there are no error messages and the logo screen remains on the monitor. I have no keyboard or mouse functions. I have placed cd's in drives and those drives appear to operate normally but no changes occur on the monitor screen. I strongly suspect that my hard drive has died, but would like some verification. One other thing, when I do first start up the computer their is a noice that I would best describe as a high speed grinding noise, which eventually stops after about a minute. I had been hearing this noise for a little while, but did not pay it much mind since it stopped after a short time and the computer seemed to be operating fine. My system has several cooling fans so I thought it might have been one of those. Any advice or help that can be provided would be greatly appreciated. Thanks
