Windows 7: Bad Hard drive? BAD MOTHERBOARD!?

Here, im like an amateur Technician. I know a lot of things, although there's something that really questions in my mind.



These are like the performance of my PC.

Normally, a hard drive can go like 32mb ( or more ) per second copying some files or something like that.

Installing Black Ops takes less than 4 or 10 minutes.

Loading a Counter Strike Source game takes around less than 2 minutes or something like that. ( For some reason. )


My friend's PC? its like fried.

Back then he told me that its not that slow. Of course i can see that it doesn't really seem to be so slow before.

After doing a format due to some reason that his PC became so slow, kinda realized that something weird is happening to his PC.

Loading a Counter strike game takes like 10 Minutes.

Installing Black ops took like an hour.

Loading a Modern Warfare 2 Mission takes like 5 minutes, In the middle of battle takes like 2 minutes. Frame Rate was really damn smooth, but its like when it reloads the sound file, it takes like a minute to load it.

Mid Battle of some game, shooting a shotgun one time sounded like BZZZZZZZZZZZZZZZRRRRRRRRRRZZZZZZZZZZZZZZZZZZZZZZZZZZZZT, then another shoot was normal.

We did another format, but it doesnt seem to budge.


One time his BIOS is telling him that his hard drive doesnt exist anymore in the system, so No boot. Next day, i opened it and checked the cables, and turned it on, it now tells me that it does exist.


So... Bad Hard drive? or Bad motherboard?

Have your friend run a diagnostic test on his drive.
It is best to use a diagnostic program from the drive's manufacturer.

However, I have found that Hitachi Drive Fitness Test works on most any hard drive.

Use the bootable Linux CD.

If the drive comers out clean, then you can start to suspect the motherboard.
