I have an hp pavilion a800n and after an hour or two the computer will just freeze and not respond at all. I have to power off the computer and then turn it back on and it will work. I ran virus scans and no virus found. I bought a new process fan because the pc is four years old and other people suggested I buy one. Any idea how to remove the pc fan and replace it with the new one?
rotate the 4 screws on the side of the CPU fan and pull each one out. then plug out the power supply wire of the fan. take your new fan and plug its wire into the same pins and fix it at the same place (fixing it on the motherboard and screwing it ).
Before powering the machine ON make sure that you have fixed the fan rightly else you may make your processor as well as Motherboard ueless.

Per HP support this computer does not support windows vista. They are saying no driver for video. I have also checked driver guide site since i am member and only XP drivers. If this is on-board video card you might have to wait and see does hp put out these drivers or some how some one gets it to work. Good luck with this.
If you are running Vista, it probable is your operating system.
Vista has alot of problems with loosing things like dirves,printers,the mouse and even itself at times.
The best thing to try is a full format and recovery and then after about 4 hours of this then spend another 6 hours getting all the updates for it. Then you can reinstall your stuff.
Or you can upgrade it to Win 7 next month and have a whole new set of problems.
Do this it will surely resolve your issue :
1. Start > Search > Type" %temp% " > click > Temp(on the top) > Select all(use " Cntrl " + " A ") > Press " Shift " + " Delete " > Click " Yes " to the prompt.

3. Start > Search > Type " disk " > Click " Disk Clean up " and just follow the all screen ionstruction. This all above removes the unwanted, dump files files from the computer... which are not required by your computer.

Sounds like a video issue. What OS is on the machine? Try updating the video card drivers. If the OS is Windows 2000 or older, update your version of DirectX as well. If that doesnt work, check system resources. Low memory, and low hard drive space can be a cause. If all else fails, replace the mouse. Mice are very inexpensive now. Keep us posted.
