I have inherited a desktop. The problem is that it refuses to boot. The monitor shows a blank screen. I suspect that the hard drive is faulty. Is there any way to confirm that the hard drive is faulty short of purchasing and installing a new one?
If an oldish computer make sure the air vents are not clogged up with dust or fluff.If so inside may need cleaning as well.When inside maybe remove your memory and clean them if needed and make sure they are seated properly when putting them back.If the computer has been moved about make sure everything is connected properly.
Even if the HDD is faulty it should still boot up and show an error message relating to the HDD unless something else is at fault too. To rule out the HDD unplug the IDE cable and Power cable from the back of the HDD then boot up again and see what happens, post back and let us know.
Try resetting the BIOS On your motherboard, usually near the CMOS batter there are some jumpers, usually with a plastic bit covering them, if you look carefully you should see the words either <Clear CMOS> or <Reset CMOS> with the PC turned off remove the plastic bit and put put it one the jumpers for a couple of seconds then return it back to its original place. This has worked for me on a few occasions
