I get a black screen half of the time that I start my computer.

Could it be a hardware failure? My Dell computer is 4 years old. I have my computer on 21 hours a day.

I ran a 'Start Up Repair', A CHKDSK, an sfc /scannow, an Anti-virus and the Dell Diagnostics disk.

I have a Dell Dimension C521. I'm on vista 32-bit.

Thanks in advance.

Hello and welcome to Bleepingcomputer.

Can you please tell me a little bit about your graphics card?

Is this an Integrated graphics card or an add-on card?

Make and model number of the graphics card if this is an add-on card.

I take it you are describing an issue where you start your computer up and there are times where absolutely nothing displays on the monitor, while other times it works fine. Is this what you are experiencing?

If this is the case and your graphics card is an add-on card, your problem may be early signs of a failing graphics card, or your contacts on your card have become corroded with oxidation.

You can sometimes correct oxidation build up issues by simply removing the card from its slot and re-inserting it again.
Please do not touch the gold colored contacts with your fingers, this can cause the acids from your body to corrode those contacts and cause issues down the line.

If your graphics card is integrated into the motherboard, you may have an issue with heat build up inside the computer, when the temperature hits a certain threshold, the graphics crap out on you.
This would be more noticeable when the computer has been running for a while.

You may need to do an annual cleaning to remove dust from your computer.
Please inspect the condition of the inside of your computer for dust issues and double check those hard to see areas as well.

Bruce.

sidhardtha,

I know Bruce has some of his own ideas for cleaning out a computer (like never use a vacuum), but there's also a tutorial on this site. Click here to get there, or look for 'Cleaning the interior of your PC' in the tutorial section.
