my computer started off shutting down during games automatically, now it was turned off, when i went to boot it the moment i press it on it turns off by its own. when i hold the reset button it stays on but nothing comes on the screen and then goes off when i let go, i tried each of my 2 ram sticks on its own, but it still does the same, the day before this happened it did this but i simply unplugged it and tried it again and it worked, this time it wont. so the power stays on when i hold the reset button and the fans stay on also, could this be a virus or what? i also had an overclocking message the day before it would no longer work and asked me to go into bios/setup or to continue, i didnt change anything and it refuses to wkr still, any help?

" also had an overclocking message the day before it would no longer work and asked me to go into bios/setup or to continue" Find the "Clear CMOS" jumper on the motherboard and change from "default" to "clear" if you can't go into the BIOS and load default setting... The other thing to look at is maybe your power supply is going out as well or maybe have a overheated CPU...
