I have had a DV5-1004nr laptop for about a year and a half now with Windows Vista on it. A few months ago I began to have issues with the video. At seemingly random times, all of a sudden the video will just go out. The screen turns black and the wireless Internet also shuts off. The only thing I can do at that point is shut down the laptop by holding the power button in and restarting it. It seems to happen if the laptop has been running for several hours. Could it be overheating? Has anyone else experienced this issue and can it be fixed?

I own a computer service & repair business in California. I've seen your problem before on several computers I serviced in the past. It happened to a Dell I owned a long time ago too.
Your notebook may stop doing what it's doing after performing a hard reset (a good idea to try first). Another problem could be the LCD inverter. It's the light bulb that illuminates your notebook's LCD. They tend to act wierd as they reach the end of their life. Sometimes the LCD turns on for a few seconds when you first turn it on, Other times your LCD will remain on for hours or even days and suddenly turn off. IF your LCD turns off but you can see a faint image on the screen still, it's definitely the LCD inverter. All LCD inverters have a lifespan and the inverter will almost always need to be replaced before the laptop itself takes a dump on you. The part costs $10-15 on fleabay.
Another problem could be a cooling issue. I've seen many notebooks where dust collected inside the heatsink's fan. This will cause any computer to suddenly turn off, however, you didn't mention whether your notebook was shutting or, or just the screen.
One additional possibility could be a problematic graphics card or a design flaw on how the heat from the GPU is dissipated, but that is very rare. I'm referring to the class action settlement on HP's DV2000, DV6000, and DV9000 series notebooks. There was a serious issue with the GPU cooling pad on the graphics chip on these notebooks, and the problems seemed to occur shortly after the standard 1yr warranty expired on almost all notebooks that suffered from this issue. A class action suit was brought against HP, and the settlement required the manufacturer to offer a replacement or fix at no cost to owners of the above HP Notebook models with serial numbers that fell within specified range.
It was sort of a recall but neither myself or anybody I ever knew of that owned these notebooks was ever notified by HP that there were known problems. HP's obligation to fix the problems free of charge ended back in 2007 or 2008. I sent in several of these notebooks to HP and they were indeed fixed.
I'm a bit off topic, but I'm familiar with the issues that are common to specific computers and your issue isn't limited to HP DV5 notebooks. I've seen it on several different brands and platforms (desktops as well). Sometimes it could be a cooling issue, a GPU issue, MAYBE a software problem.....but most of the time, your issue has more to do with an illumination problem. That's the LCD inverter, every time. That part costs only $10-15 on fleabay and it's very simple to install. Google "LCD inverter" and you'll learn a whole more elsewhere than you will on this forum. The LCD inverter in every laptop will need to be replaced. Usually every few years. They get hot, just like a light bulb.

I'll try the LCD inverter and see if that works.

I have the same problem on my DV5-1113us. the screen will go blank after random amounts of time. Is the video inverter something hard to change? I took my laptop into a repair shop and they said the laptop worked when they swapped out the hard disk and installed a new one with Windows 7. I didn't want to upgrade to Win7 but it looks like I will have to try. I am trying to not put to much $$ into the laptop as it is 3 years old.
