A short circuit could cause several different problems with your computer, most of which will require a new motherboard, processor, or both. Is it not powering on at all? If not, then your motherboard is most likely fried. I would suggest taking it to a local computer shop, or you could contact my business and arrange to send it in to be diagnosed and checked over.

Most of the time the settings are either found in the control panel and then mouse or else in start > all programs> and control (sometimes Catalyst center) you can also right click the pointing device in the taskbar and in device settings it will allow you to disable it from here.

see if ur device needs any additional driver or not, if so try downloading..
look if ur device itself is faulty by replacing with a standby..
2)is ur m/b compatible..check with a substitute/standby..
3)if ur hdd is making any humming noise (like 'tic tic' or 'kirr kirr')..if so it is likely to be replaced..

You can download drivers from the compaq support site.
An alternate solution is to use a driver update program to find and install missing or outdated device drivers.

This is issue with laptops when you type fast sometime you hit the keys from the side and overtime they come loose or from overheating…the only way is by replacing the keypad…sorry.

It looks like your system is dangerously overheating!!!! a standard machine should be around 20-40 what size is the video card? how many fans in machine? what is speed of CPU?

My best suggestion would be to use an external usb soundcard.

Appears that recovery disk #2 is bogus. U can try to get a new set from HP (fat chance!) or you can do a reload from a normal, retail OS disk.

Hello Most laptop or PCs, has a combination keyboard pressing keys, that invoque the restore routine. usually F11 or F10. others has DVD, check and see what you have of these two. in the first one, you recover from a disk partition the whole OS.

Its all about go to HP page, and bios updates, the instructions are there too! but be aware you have to be more specific on model, and BIOS dates.

You may have a virus, malware, adware, a browser hijacker, or pups (potentially unwanted programs). A. If your computer will boot and you can operate it ok... Download and install Malwarebytes and Superantispyware (Note: If you can\'t do the download on your machine, do it on a friend\'s, put them on a thumb drive, and install them from it). Then scan your computer with each program, and quarantine anything found. B. If your computer won\'t boot, or can\'t operate properly after boot... Tap F8 when you are booting, select "Safe Mode With Networking". Download and install Malwarebytes and Superantispyware (Note: If you can\'t do the download on your machine, do it on a friend\'s, put them on a thumb drive, and install them from it). Then scan your computer with each program, and quarantine anything found. C. If this process finds malware, to keep stuff like that from coming back, I recommend you get the paid version of Malwarebytes.Good luckG
