I tried to innitialize some diy changes to my pc to improve the speed and performance, but now i cannot use a lot of the programs and i cant connect to the internet. But i have also forgotten my bios password so i cant get in there to try to set things back to the original factory specifications.
You will have to remove the power cord, remove the batteryand remove the CMOS Battery that is located on the motherboard. On mostcomputers you will have to take the laptop apart to get to the cmosbattery. On some systems it looks like a silver nickel that you will needa small flat head screw driver to pop it out. On other systems it will beinside a vinyl covering and has a cable that plugs into the motherboard. Once you remove the CMOS Battery, let it sit for an hour or two then put itback in and put the laptop back together. Boot the machine and you'llprobably have to go into the Bios or System Setup because the system will haveforgotten the date, time and password.

Underneath the ram (remove ram) is a jumper marked J3
short this out for a couple of seconds.
This will reset bios right back.
Boot and go straight to bios (F2) and set your options as needed there.
Eg date, time, drives,and any other options the bios needs to be able to boot the machine. When you have done make sure you SAVE then exit which will re-boot.
If you didnt mess any bios settings you should be back in business
