Strange boot problem, any ideas ?

[Stupido]

Intel core 2 duo e4500 at 3gig
gigabyte ga-73pvm-Sh2
4 gig ocz value pc 6400 ddr2
Asus xonar dx
Hipper r-type 650 W Psu
Asus Eah3850-256mb
silverstone Tj08 case

This problem doesnt happen all the time seems to be about 50% of the time, so its getting very ,very irritating.

When it goes wrong. from a cold start i press the on button.the case lights up. and system and case fans start to spin , but the graphics card goes into overdrive and the graphic card fan spins at !00%, makes a huge amount of noise.I can hear the HD ticking away as it loads windows but the Display stays black.Xp does boot and i can press enter on the keyboard and even type in my windows password, but the fans still running at 100% and the screens still blank.

I might have to reboot 3 or 4 times ( sometimes more )for the pc to boot up normally , i.e the Videocard doesnt run up to 100% fan and will display a screen image.

its a weird problem .I have tried lots of different things trying to sort it out to no avail , so im posting here in desperation really.

Any ideas ?

pretty much all the obvious things really . did not want to say too much as was hoping for some replies in case i had missed anything.

And while i have updated the bios i havent reset it via cmos jumper , so ill go try that .thank you for the idea

thanks for all the replies.

Looks like i have got it sorted.

I definately had not reset the cmos after i last flashed the bios.At least i cannt recall doing it.Should have known better really, been building PCs boxs since 1993.

Anyway ,in order to get access to the cmos jumpers i had to remove the video card as its a Matx mob/case. Its now booting up properly .So the Cmos reset or the re-seating of the video card solved the problem. However i had already re-seated the video card before so i think probably it was the cmos reset.


thanks again for all the replies.
