Help with Inspiron 530 Desktop?

Remove the computer's cover or side panel and make sure the Video card fan is running and is free from dust bunnies.

In safe mode your Video uses default drivers.

If the Video adapter is the original, I would download a fresh copy of the video drivers using the service tag number from the sticker on your Dell from their support website. Make sure you know where they downloaded to so you can find them later.

Since you didn't say what version of Windblows you're using all i can suggest is that you go into the device manager and uninstall your graphics adapter and restart your computer.

When it detects your video adapter install the downloaded software.

If it doesn't repair your problem i would say that your graphics card is failing and will need replacing.

You could have any number of different problems and it will be a pain figuring out which one it actually is. You could have an IRQ conflict - 2 devices trying to use the same IRQ. It could be a compatibility problem, or maybe you simply don't have enough power/system memory to pull all your devices at once.

You don't say which OS but windows will allow you to boot up and then step through each process which can help you pinpoint where or what device is causing your problem. Or you can try disabling each device from controlpanel one at a time until you isolate the problem. Of course, you could also have a bad chip. Or a bad/otdated driver. Or a bad battery. Start with the simple things first and work your way up to the hard ones.

Unless your prepared to take a few days and are fairly computer literate, not to mention enjoy getting a headache, you may want to look around for a local computer shop with a fairly reasonable "troubleshooting" price.

Good luck.
