Hello
I am quite well with computers, but I have ran into a major problem that I've never encountered, and I have no idea how to fix it. I am in desperate need of help.

The problem:
With the computer being off, I press the on button. The screen does not come up, it stays black, however the tower is on, kinda, but I can tell that maybe 15 seconds after it is turned on it freezes because the green light isn't flickering anymore.

I have Windows Millennium Edition on a Compaq Presario with the video card Nvidia Vanta, probably 5-6 years old.

History/ How it got this way:
It had been randomly freezing, with no messages at all for no apparent reason, a few days ago. And i would just manually shut it off. It got to the point that I would have to turn the power on and off a few times within 20 seconds, just for it to boot up. A while after that it had escalated so badly that i would have to hit the power button on and off for about 7 minutes
just to boot up. But It has now gotten so bad that no matter how many times I switch it on and off it will not boot. Normally the like on the screen would turn from orange to green the same second i turned on the power. But now it will only stay at orange. So no I cannot even run it in BIOS or safe mode.

I hope that this is enough info, this is my first time posting. If you need more info just ask. I thank you for your time and I wish for your help.
