I'm having a really weird problem: When I turn on my computer, it just freezes with a BLANK screen, without even showing the BIOS splash screen thing. I can tell it's on, since the power light indicator thingy lights up and I can STILL open the CD drive tray. And the really weird part is that if I restart it once or twice, it works fine.
(I have an HP PAVILION ze5185 laptop with PhoenixBIOS (can't remember the revision number) and Windows XP Home Edition w/ SP2.)
Please help me!!! It's getting really annoying!
When a PC starts it has to go thru  a POST (power on self test). This will loads BIOS, when the BIOS finish loading. The OS starts to load. So if u have to turn it on and off several times to POST, it may be several things:

bad power supply (PS)
bad MB
or u might have to upgrade the BIOS.

Try upgrading the BIOS with the  latest version and see what happens. If this works great, if not check the voltage coming from the PS. Last u might need a new MB

Good luck and let us know what happens.BTW is it making any noise. It is giving a series of beeps. If it is giving a series of beeps count them, WRITE down the number of beeps. go to MS Support or the PC manufactor and do a search.
