Hard disk problems. Death often. Bright lights have been hard

Recently, when a computer crash frequently, the phenomenon is the first hard drive has been bright lights, and then on the death, according to the chassis on the restart after the resumption of the regular keys to the end memory testing to detect other post-ide interface when stopped, must be in accordance with Power button and then shut down, and so it will start if off immediately after the start or not detect the hard disk, as well as access to safe mode to use is no problem,
my hard drive models Samsung hd080hj, is the main board QDI P4945G, Kingston memory is ddr533 512 * 2.A fast computer with a recent three years on this issue.I would like to ask you what it is.Thank you,

aging components? CPU temperature too high? hard not to detect it should not be caused by Bad Track, the issue should not be hard.

if the CPU temperature is too high, under the proposal clear the fans first check HDTUNE Now take a look at some of the hard disk, such as temperature, health status, the error scan to see if there are no Bad Track.Do not installed the system, hardware problems and software you have anything to do.

Upstairs, said one of the It is true that HDTUNE first check to see if the current state of the hard disk, such as temperature, health status, the error scan to see if there are no Bad Track.

Propose to the chassis to remove the dust like to see there is no interface cable Loose, if there are problems after the deal, which is a circuit problem.

If you do not find people to give you some testing to identify problems.Resulted in the death of the reasons:
1.Garbage system There are too many to keep the system clean.
2.To open the proceedings too much, it is necessary to minimize start-up items.
3.CPU graphics or high temperature, heat check.
4.Poisoning .Use of legitimate anti-virus software, then reinstall the system down hard on the other machines try
