black screen boot up problem

Postby cantsleep2nite on Tue Jan 13, 2009 5:46 pm

I have several lock ups & crashes over the past few weeks and now my pc will not boot up. It either starts (nothing on display) briefly with power light on & hard drive light blinking briefly & stops.... OR when I power up all lights (both disk drives & hard drive) flash constantly & fan, disk drives, & hard drive make noise...but never stop...never get to anything on screen. Any ideas???

HP Pavilion D4100E
AMD Athlon 64 x 2 dual core, 2.2 GHZ
1 GB DDR 400 MHZ SDRAM (2 x 512)
1 250 GB 7200 RPM SATA Hard Drive
1 DVD+/-R/RW disk drive 16 X
1 DVD-ROM disk drive 16 X
1 256 MB DDR Nvidia GeForce 6600 video card

What I would do is to try to eliminate what the problem might me. Take out your graphics card, memory modules, hard drives and other cards from your computer plus any perhipials attached to it so you basically only have the motherboard and power supply. Start the computer and listen to it, it should beep or have any indication the motherboard gets power. Next step would be to add one memory module to your motherboard and do the same, then add the graphics card to see if it turns your screen on.. etc you do this until you have all component added to your computer, and if it stops working while doing it, the last component you put in is probably faulty.

You can also try to eliminate the problem the other way around, take out a part of your computer and turn it on to see if it works, if not take out another part etc..

I have a feeling though that your computer got overheated and the cpu might have been damaged. If you have an extra cpu lying around try to replace your cpu you have in your computer with it. If that does not work and nothing else works, it is probably because of a faulty motherboard.

Before you try anything i mentioned above, try to re-seat your graphics card into another slot in your computer and turn it on.

Let me know what happens! Might sound intimidating, but it is the only way to determine what is wrong.

I believe I have it narrowed down to the video card. I went thru a step by step process of plugging and unplugging memory, video card, drives, etc...each time I rebooted and it tried to boot up (rec'd post beeps) but when I plug in the Geforce 6600 is when it really starts acting up.
The video card fan does not run at all during these steps.
Could a bad fan prevent the card itself from working?
BTW, I don't think I have another slot for the video card.

I was going to upgrade to a better video card, but my power supply is rated 300 - 350 watts and some recommendations are for 400 - 500 watt and up for the newer cards.

Thanks for your help.

No problem! The elimination process is the best way to find faulty hardware if you suspect having any but can't determine what component it is. I am glad you found out what it was. Had a few problems with my own graphics cards acting up like that, but they always got resolved when putting them into another slot.
