RAW shuts down PC

The past couple of time's viewing raw images on the Canon DPP the computer just shuts down, but if I view JPEG its fine. I'm shooting with a Canon 1D MarkIII and the card is a Lexar Pro SD 1GB 133x and the computer is a HP Pavilian zd8000.

First I would uninstall DPP and then reinstall. If that does not work you may want to make sure the file extension (.raw) is registered with the computer. In Win7 > Start > then in search program and files type "file type" without the quotes.

I will try the uninstall of DPP. The file extension (.raw) should be registered with the computer. I've been opening and viewing the files fine for a few years and it just started now.

Uninstalling DPP or playing with anything in software won't do anything.

It is most likely shutting down from over heating, which is a hardware fault.

Most likely overheating. By computer standards that's a pretty old laptop. Check your vents for dust bunnies.

If it was the heat wouldn't it be turning off all throughout the day since I have it on from morning to around 11pm. It runs hot all the time even when it was new. The only time it shuts down because of heat is when I have it out in the backyard doing White light photography of the sun. When I open the RAW images in Photoshop it is totally fine and does not turn off. I'll have to test out RAW's from my compact card to see if it does the same thing.

anything's possible, but if the unit's just idling along then it doesn't really have to work hard. Processing larger amounts of data makes it work harder & working harder generates heat. Heat can affect almost anything from motherboards & cpu's to memory.

There's probably a bunch of monitoring apps out there to log what various temperatures are, I'd be inclined to get & install one & see what's going on when the issue occurs.

Ok, so I downloaded Core Temp to see how my temps were running normal internet stuff and just doing JPEG images. With internet stuff it really never got beyond 65C and editing JPEG images in DPP it got up to around 74C and the loads were not that high. But when I got to the RAW images using DPP the loads would sometime go to 100% and the temp would go over 81C and when it got over 81C by a few degrees the computer shutdown. The odd thing is that when I open the RAW images in Photoshop Elements 9 the temp would be around 74C and the loads never got close to 100%.

In a few days or weeks I'll take apart the computer like I have done before and clean out the fans and the heatsink and the whole laptop. Since I have I'll have the laptop taken apart should I put new thermal paste on? I have not done that with this laptop yet. Would it help with the heat?

Few days or weeks will probably be too long to save the laptop. It takes a fraction of a second of overheating to permanently damage your CPU. Thermal paste isn't the issue. Once it's there, it's there. It doesn't really go bad. It's ceramic paste and sealed as it were. It's dust bunnies, your fan blades warped/melted and not pushing as much air. If you do have to pull the heat sink off, of course you need to clean and reapply the thermal paste.

If I do reapply the thermal paste what is the best method? I have read where they say doing a small dot of paste in the middle works better then anyother method. But then there is ones that say to put a dot on and then spread it with a credit card or something like that.

The instructions will be on the package the compound comes in. I think you're confusing conflicting applications though. In truth I do both. I clean the surfaces well with alcohol. Then I spread some on both the CPU metal backing and the heatsink. Scrape it all off. This re-primes all the micro fine pores. Then I put the small dot on the CPU backing and press and twist back and forth a degree or two to seat.

I am surprised you have enough patience to edit RAW files on a computer that old and slow! I'd use this as the perfect excuse to get something new with an i5 or i7 CPU.

Many times it's not the CPU that overheats on laptop, it is the battery. Also, based on a google search it looks like the ZD8000 is/was a notorious overheater.

I have a 7 year old desktop with similar specs 2.8CPU,only 1GB of RAM and it handles my RAW files just fine! Granted they're only 6mp.

I use Arc Soft/Infanview to view the raw files. Then edit in Ligthroom 3.5..... runs flawlessly

If your computer and camera are from about the same year, it's no problem! It's when they get about 5 years apart that things get painful.

I have fixed many overheating laptops, and generally it is the dust bunnies, so it's best to evict them! I usually blow it out with compressed air (I have an air compressor). Blow it out reverse direction of the normal air flow (so blow it in where it usually comes out) that usually clears them out. If you don't get many dust bunnies, then you might have to take it apart. Static warning: Make sure you avoid any kind of static, best is to do it in a room with no carpet, and standing. You don't even have to feel the static shock for it to kill your processor and other chips on the motherboard. if you don't have a grounding strap I find it a good idea to try to keep one hand on a metal leg of the table or just touch something metal frequently. The thermal paste is not supposed to go bad, but I have seen otherwise. Sometimes with enough overheating (and heating and contracting of everything) the paste gets hard or looses contact and then doesn't cool as well. So if you do take it apart, make sure that you clean both the processor and the heat sink alcohol is a good idea (as long as it is rubbing alcohol and not the drinking stuff). If it is one that has the graphics processor on the heat sink too, and it has thermal compound on it, make sure you clean it off on both sides as well. If it is just one of those foam looking pads, those are usually fine to just leave alone and put back as they are. When applying the thermal paste, I usually just put little dabs all over the processor and smear it around with the tip of the thermal paste tube. You don't want too much, but it is worse to not have enough. I like artic silver thermal paste. hope this helps
