make sure all dust is clear of the processor heat sink. then if you overclocked the processor you may want to back off overclocking a little bit. make sure you have plenty of thermal silicone paste in between your processor heat sink and processor
Any error code for a hard drive isn't good, and should be reason to get a new one right away. So long as the drive is still able to be accessed, you have a chance of retrieving your data. There are free utilities to help you 'clone' the data to a new drive, but you may want to ask a tech-minded friend for help if you've never done it before. It sounds like the drive isn't dead yet, but is definitely on its way out. Good luck!
is this wifi.

The best thing to start with is to service the pc. You have to put new thermal compound on your CPU every 3months . See me on facebook Nic fourie on how to service. Your own pc
Right click on the speaker icon in the system tray (bottom right, next to the date/time) and select recording devices. It will give you a list of whatever devices you have on your computer that are designated to record sounds. Choose the on board microphone, right click, and select disable device.
Something is jammed in one of the fans ???
(there are at least 2 = one at the back of the power supply = should be easy to see - and one inside on the CPU heatshnk (harder to get to)
Else its likley the Power supply or monitor is 'shorting out' internally ..
If it's just 'ticking' it's likly your hard drive going bad (unless, of course, you happen to have a CD/DVD disc inserted into the CD/DVD reader ...sometimes these 'tick' during power-up as the PC tries to boot from the disc :-) )
I know this post is over a year old, but i feel like chiming in anyway. The motherboard may have suffered from cheap cap syndrome. This happens when the components used to populate the motherboard were poorly made with inferior products. The capacitor's may have swelled up to the point of uselessness. This would give you post errors, or no post, or even no power. This is not to rule out the power supply, but it is more likely the motherboard.
To test the power supply, unplug the big 20+ pin plug from the power supply to the motherboard, and use a conductor such as a paperclip to connect the one and only green wire in the mix to any black wire (there is a black wire on either side of the green one, you can use both)
If the power supply is still good, the fans and drives will come on and spin up when you make this jump with the paperclip.
If for some reason you notice the fans twitching but not spinning, then you know the power supply IS bad!
With the tray open, visually inspect to ensure the cd is still in line with the spindle. Something long and thin (such as a thin knife or spatula) slide it between the top of the drive and the top of the cd.
Carefully tip the tool down to try and release the CD from the spindle. Do not attempt to force it! If it is not jammed in the drive, the CD should drop free. Carefully pull the CD out of the drive.
Look at the CD to see if it has been damaged from the drive. If the CD will not come out, it needs to be take to a repair service.

You'll need a T5 screwdriver for most of the bottom screws. When I did this project Ace Hardware had the screwdriver bit for my drill for less than two dollars. Good luck!

Black screen - no flashing white cursor in the upper left corner - no picture at all, i.e. the initial Dell start-up screen doesn't show up either:
- LCD is dead or isn't getting a signal - not an easy fix; or
- the LCD isn't being sent a signal - holding down the function [Fn] key and press display Function key to toggle through its settings (LCD panel only, Rear VGA output only, both LCD and VGA output)
Black screen - flashing white cursor in the upper left corner - the screen goes black after the windows loading screens come up but before the windows login screen comes up - it is probably a windows video driver problem. Try starting in Windows Safe Mode with VGA. Press [F8] after the Dell startup screen disappears to access the windows startup menu
