My Computer Wont Boot Up!!

[mikevs]

So I was browsing the Internet, and my computer froze, I tried to restart and the computer would not go through the normal boot phase, or beeps. My HDD light flashes and that's it. My computer screen goes blank and goes into hibernate mode.

I opened my computer and checked all the cables, which are all fine and connected. I don't know what the problem is. I have no viruses or spyware at all and recently defragged my computer with Smart Defrag 2 which I never had problems in the past. Can Anyone Help? Thanks

Memory maybe? Try using 1 stick and see what happens if same try the other stick(s)

Pull out the soundcard and see if it boots.

Worked on a old rambus pentium 4 hp and it did this also till i pulled out all the add in cards.

Booted up and ended up being a bad soundcard and a printer card.

Hope this helps and hope you figure it out.

You don't say which version of P5Q you have (there are quite a few variants) but if your case has a speaker (or the motherboard has one built in) - try pulling all devices (sound card/hard drive/video/memory) so that you have just PSU/Motherboard/CPU and FAN
then power it up and see if it beeps at you (it should - in a pattern of long and short beeps). Also check to see if the CPU FAN spins when you try and power it on.

If it doesn't, then you've likely got a failed motherboard or possibly a bad PSU


If it beeps, then disconnect the power and reinstall the RAM, test and then reinstall the Video Card
