After a while running it shuts off. fans seem to be working but, not sure if 100%. Does "the professor" work for this type of problem?


I had the same issue with my desktop HP Pavilion. It turned out to be a faulty power connection in the actual power cable right where it connected to the powersupply in the back of the computer. I had the power supply go out on the same computer - new one is about $30 for a replacement - installation is extra. To determine if it's the power cable you can power up and wiggle the cable right at the back where it plugs in. If it drops off immediately then you'll need a new cable. To determine if the power supply is faulty unplug the unit, take the cover off and measure a spare white connector coming off the power supply. You should have +- 5 volts and +-12. If you don't have within 10% of these voltages then replace the power supply

My HP dv5-1125nr has had a fatal error and has completely shut down. How do i do a recovery?


Turn your computer on. Keep pressing the F8 key until the Windows "startup" menu appears. Choose "Safe Mode". Click "Start". Click "All Programs". Click "Accessories". Click "System Tools". Click "System Restore". Select the most-recent "Restore Point" before the problem, and let Windows restore itself to that date/time.

Hp Pavilion zd8000 shuts down loosing all opened windows


There is a software called "SpeedFan" which you can download here

This software will tell you the internal temperatures of the computer (so you can figure out if overheating is the problem). Most of the time overheating is due to excessive dust inside the laptop. The best bet is to get a can of compressed air and clean the inside out. This does require some disassembling of the system, so if you are not comfortable doing so I would advise you to take it to a local computer shop.

Another solution would be to purchase a "Laptop Cooler", this will lower your temperatures anywhere from 5-10 degree's, but can get annoying to lug around with you. You can view some laptop coolers here

If you happen to run the Speedfan application, let us know what the temperatures displayed as, and I can tell you if it is running too hot!

check the fan (top rear of the computer) , make sure it runs when you start the computer. if it is NOT running the power supply may be the cause.
also you may need to remove the case and inspect the fans inside. you shoulkd be able to remove a couple phillips head screws on the back of the computer and lift the cover off or at least the side making the guts of thhe computer visible.
once open , inspect all the fans and cables, especially the fan on the main board and the metal piece with fins undernieth it, this tends to collect dust causing the cpu below to overheat and shut down the syatem to protect itself. The number one cause of crashes is overheating.
look at these things to start and post your findings and we'll move on to another step.

HP Pavilion a1010n won't start


Make sure there is no dust covering the computer fan. If necessary use the recovery CD or a new Windows XP CD.
