So wait, its asking for a BIOS/CMOS password? If so, one thing you can try to do is remove the CMOS battery. The battery is about the size of a nickel and can be found on the bottom of your laptop. You'll have to unscrew a few things to find it. Once you do, take extreme precaution when touching anything inside the computer. I would recommend getting an Anti-Static Wrist strap (sold at Best Buy). Once you locate the CMOS battery, take it out. Keep it out for about a minute and then put it back in and close everything back up. When you do this it usually resets the BIOS/CMOS password if there is one. Hope this helps!

you need to be techy on this one. you need to open the laptop. before you do that, be sure to remove all source of power (ac adapter and battery). press and hold the power button to drain all excess power. check the motherboard and reseat the CMOS jumper. it looks like a tiny pin. after reseating the jumper, reconnecting power and turn on the laptop.
i hope this helps.

probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/addon/daughter cards..
..plz do check the following as in order:..
the Hardware part:..
1)a) in power-on mode, open/unplug the data/vga cable of the monitor from cabinet..see if raster or 'osd' is appearing on the monitor screen..if so monitor is ok..else replace the monitor and see..[not applicable in case of laptop]..
b) in case of laptop try to get output from external display unit/monitor using vga port..if there's proper display in there..the problem is probably with either the 'lcd' or 'ccfl' or 'inverter circuit'..
2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..
3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..
4) see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..
5) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..
6) remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..
7) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market)between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..
8) on main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(espabove1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)..
9) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v(yellow); +5v (red, green~ps-on, violet~pg& grey~sb); -12v (blue);-5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic',or pwm switching regulator circuit..look for defective protector-transformer/resistance (esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..
plz give higher priority to step 8 & 9..
the Software part:..
1) hv a licensed and UPDATED antivirus installed (i prefer avg/kaspersky,remember, without updation a full version antivirus is useless)..
2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..
3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'remove all the unnecessary startup items from here..(if u can't find what to remove, post me/us in ur comment with all the items listed in each n every tabs herein)..
4) remove all unnecessary software from add/remove programs..
5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..
6) disable the following:..
a) 'Automatically Restart' right click on my computer->properties->advanced->startup n recovery->(un check on the) Automatically Restart;
b) 'Error Reporting' right click on my computer->properties->advanced->error reporting->disable error reporting->(uncheck on the) 'but notifyme when critical error occur'..
7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880
if u r not a professional, always better to seek advise from ur system admin/vendor....
