Please list your system specs including the power supply. You may just need to reset the bios.

well i just removed all the connections from the motherboard (memory, hard drive) as one of the forumer i have read and also clean my CPU... after 5 minutes.. i connect it again and start it, after which it boots normally i tried it thrice and then i think it backs to normal.. the next day i start my CPU to check if its back normally, it boots well and tried it again to on and turned if off.. but when i click the restart button, i encountered the same problem, it took 5-10 minutes before it starts..

now i encountered a new problem.. i played AIKO global (online games) while I leveling up my character, it hanged on, i tried to pushed control alt delete, alt tab or even escape to think it will returned to windows but nothing happened. it happened twice, i have no choice but to hold down the power button of my CPU to turned it off.. after which i tried to opened it again and from the booting up to the windows, it doubles the letters, the icons and even the mouse not working properly.. and then the display turned blue and said "error has occur...." and automatically turned the display off fast that's why i don't even read the error fast.. but the CPU is working...
