Specs: Windows 7
I have HP dv7-3079 ,64 bit windows 7 Laptop - When i surf the internet the pc is fine but now i am having trouble when streaming videos. it makes the pc freeze, then it crashes and makes a noise and shuts down. if i try to restart it wont. you must wait 15-20 min before it will startup. i dont know what is going on; is it a overheat thing or bad drivers, but if it was drivers or flash like java, why would i have to wait to restart after a crash/shutdown. i also have Warpia installed on pc for wireless to tv hookup. i blew air through pc to check for dust buildup, checked the cooling fan and it seems ok. if it is program or driver related, why does it only act up when i have been streaming videos for a while? how come when it crashes why will it only reststart after it has cooled down a while...if it is heat related. this all just started within the last month even though i have been streaming videos for months before that. Thanks, Please Help!

It does sound like an overheating issue, the streaming video is just a more continuous use of the systems capabilities and therefore more heat. Make sure you are using the laptop on a hard surface (never use a laptop on a bed or lap without a laptop cooler or at least a lap desk), this will ensure that the bottom vents are not blocked by fabric, etc. I know you said you blew air through, but if you have not, use a compressed air can (Radio Shack, etc) and direct the air into the openable ports (removing the battery, opening the RAM access panel, and anything that easily opens) and out of the normal vents to make your heat sinks and fan are free of dust. Install SpeedFan and monitor your temperatures and fan rpm first at idle, then after browsing for a half hour, then while streaming video and note down the results. While you should see an increase in the temperatures at each stage, the changes should be reasonable. The fan speed should be relatively constant unless the temperatures rises high and then you should see an increase in fan speed. Post back all of the numbers. for additional advice.

Thanks for the reply, ok i never use the pc on soft beding, I have a laptop stand, an I did pull off the back covers off the laptop when I use my air gun and the fan is free of dust and moves fine. so it might be a heat problem? when the pc is streaming it will get a little hot an the pc will make the fan run faster to, I just don't no why after alot of time an streaming sports now it is having this heat problem.? I would like to monitor the temp an see if I can keep it running cooler. I hope my cpu ant going bad?

A program like SpeedFan will allow you to monitor your temps real time. If your video is displayed in a window then speedfan can be right next to it on the desktop. Your next steps will be determined by the base temps and the amount and rapidity which it rises, and how fast it recovers after you shut down the high usage and speed step (or whatever your cpu uses) kicks in.
Another thought... Check for other programs running in the background and shut down unnecessary ones (use msconfig start tab) to reduce the stress on the cpu.

Hi, I Installed speed fan but don't see the fan speed moving in the program, but i know the fan is spinning and can hear it. am i doing something wrong? other features are working like temp, cpu core, but not fan 1 0 rpm fan 2 0 rpm fan 3 0 rpm (that's what it says in speed fan). and i don't think i have more than 2 fans on this pc.

Apparently Speedfan is not able to monitor the fan on your system. On a desktop fan1 is usually the CPU fan and the case fan(s) are listed after that (sometimes one is skipped), I guess you will have to proceed without that. You will still be able to monitor your internal temperatures so you can at least verify the cause of the freeze/shut downs.

Conclusion:
it's definitely a Heat Problem after monitoring the temperature on the pc at idle and streaming videos. I noticed the temperature would continue to rise when streaming untill the pc would crash, after multiple attempts to clean the pc with air and even taking the laptop apart, I could not find any dirt or visual problems. so i have been using a laptop cooler to aid in keeping the temperature down when streaming or running multiple programs. It didn't totally fix the problem because I still must monitor my temperature at all times or risk causing damage to the computer by overheating. I want to thank you for the tip (speedfan )download and your thoughts. ps. I thought i would try a new approach- got out my Hoover vac- this thing has a strong motor- very good suction. So i put the hose on the back of my pc over the cpu vent fan and couldn't believe what came out. Fuzz and lint must have been packed way down in the fins or under the fan. Well that made my day. It must have insulated the cpu by keeping the heat in. So we're back in business - temp much lower again!!

Well, I'm back with the same problem. It seems to have gotten worse. This time the temp does not seem to go high at all and yet it still freezes up the PC until it crashes. I'm not even necessarily streaming flash at the time. I am at a loss! One thing that is consistent is that after it crashes I can't just restart. I have to wait a little bit. Any ideas would be appreciated so I can figure this out once and for all!!
