Computer is not booting up.

[DarkSt-A-r]

My motherboard is ASRock k7vm2.

OS is Win XP Home

Graphics is Nvidia 5200 MX

Ram is 512 mb

When I boot up my computer there is just a black screen on my monitor. Nothing loads up. It is just like if the computer is not on and the monitor is black. The fans turn on but my drivers don't seem to. The first night it happened my cd-rom was working, but now there is no power to it. I tried booting from a floppy, but that seems to not have power too. It did something similar to this a week before but all I had to do last time was unplug the power cable and plug it back in, but I did give the same response, the black screen.

Thank you

Maybe your powersupply is busted? Are you sure that there is no power going to your drives? Have you resently installed the Graphics Card? If power is being fed to the drives, try plugging the monitor into the onboard monitor port. If this works your will need to install all the drivers for your graphics card, restart the PC and go into the Bios, Disable the onboard graphics. Then plug in your screen to the Graphics card. and reboot.

When you start the computer do you get anyfeed error messages to your screen?

I'll second the powersupply. But also double check that all your cards are seated correctly. If your video card or any other card is slightly askew it can also cause this kind of problem.

Assuming all that is correct unplug all the devices (drives) and see if it'll boot up to a bios screen. If it does start adding devices back one at a time and see if the problem returns.

Well I got the drivers working last night. Some other forum said I had to reset the bios byt taking something out of the motherboard. So my drivers work again. The first night this happened they were working but stopped the next. So I guess that rules out the power supply. When I press the power button all the drives come on but there is just a black screen on my monitor and no beep sound. I tried plugging my monitor into the onboard graphics card but that doesn't help. I also tried unplugging the drivers; its kinda like if my computer is not getting the directions from my master drive.So I am thinking it has to be the bios. Any help would be greatly appreciated since WoW is probably coming out this weekand and I need my computer working again.

O yeah, this all started when I was playing Wc3 and my computer froze at the loading screen so I turned my computer off since all keyboard commands were not working. I also head it might of been if I hit the sleep button and the computer got stuck on sleep and since at the boot up of the computer the monitor doesn;t work, you are stuck, but I don't know.

Thank you

Did you reset the bios by flipping a jumper over on the motherboard? If that's what you did your bios will be back at it's default settings if not do it before starting any of this, the idea is to get everything back to basics and start narrowing in on the problem.

Well back to basics. Pull everything off the board all cards and unplug the drives. Then reboot see if you get any error beeps. If you do then it's getting that far in the post sequence so start adding devices back in one at a time and see when it cacks.

If you have everything off and nothing remove the ram also and reboot see if you get any beeps. If you don't then also remove your cpu and boot up. With no CPU and no ram you probably won't have anything happen at all. So it's back to 1 at a time plugging things back into your mobo and seeing when it fails.

I'm not guessing when I say this: Your processor is bad. I've seen it several times before.

[lordbean]

That's not necessarily true. I've got a mobo where if any IDE cable happens to be in backwards, I get a black screen with no beeps or post.

True, and I have also seen MB's that will not allow a NIC to be placed in a certain PCI or you get the same result, but we know his cables weren't plugged in backwards, and that he hasn't added in a card...the machine just quit...he didn't make any changes.

Hide and watch...the CPU is toast.

[lordbean]

Actually, according to what he's saying about the CD-ROM drive working and now not working, my guess would be more along the lines of bad power supply (which has at this point shot itself out). Bad mobo follows as a secondary suggestion. If the CPU is fried or absent, the mobo will beep like mad at you.

I disagree, but I guess we will eventually find out huh?

Your interjection on the condition of the PS may be right-on however.

[lordbean]

btw, I just noticed this topic was two weeks old before you posted just now. I'm gonna leave it alone, since the problem has likely been solved or otherwise disappeared by now.
