check whether your SMPS fan is running the back side of the cabinetand also the cpu fan if you can open the system case. if the both fan is running fine then rmove the CMOS battery and start the computer after 2 or 3 sec the cpu fan will stop that means BIOS is cleared reinsert the battery and boot the system go to BIOS and go to load default setting and enter(press DEL or f2 to enter BIOS) after that press f8 and go to safe mode (not work with win98)it will take some time,after getting in to the OS scan your computer for virus with best and latest updated ANTI VIRUS. let me know whether it is working ot not. if not working kindly let me know what the exact problem is write all the process you follow to start your PC reply me soon

SOURCE: Green light flashing on back of unit near power cord also green light flashing on motherboard near power supply plug in.

I would suggest trying to replace the power supply. If that does not fix the issue, i would need to hear more about the computer.

Unplug the tower

Remove the ram and turn the tower on wait till it give you fast beeps. (telling you no RAM)

once that happens shut the system down by unplugging it again

Re-install your RAM and try to boot again
