New System Fails to Dislpay BIOS

[dmckenz]

I began the assembly of my first system last night. Unfortunately it is having a problem booting up and will not display the BIOS screen. Im using an Intel P4 3.0GHz (800) with an MSI Neo 875P FIS2R motherboard, Corsair 1024mb PC3200, Dual Seagate 7200rpm SATA 120gb, and a Prolink GeForce 5600FX 256mb Golden Limited. I made sure to install everything correctly into my Thermaltake Xaser III case with 420w power connecting all fans and the necessary cables. With the power on everthing works fine and all fans and lights spin up. The diagnostic lights on the mobo show a combo that indicates it's initializing the VGA and system clock (Second step during power up) but it will not get past this point. There is no output to the display, I tried 2 monitors and used the VGA and DVI adapter but nothing changed. I even swapped in an old GeForce 256 and the mobo is compatible but there was still no BIOS screen or change in the diagnostic LEDs. Any help is appreciated! Thanks.

First off dmckenz, welcome to AT

As to your boot issue, if you've swapped different video cards and monitors, and you are sure they were seated correctly it's possible that your MB AGP slot is bad

Hi dmckenz, welcome to the Forums

Take a close look where your video card plugs into the AGP slot. An AGP slot has two layers of contacts, and an AGP card has two sets of contact fingers. If you can see any hint of the fingers at the card's connector, it's only into the slot halfway. I've had this happen to me on a new motherboard and it really took some pressure to get that card seated! :Q

Considering the detailed and helpful info you gave, this seems like one of the most likely culprits. I assume you did 1) plug a 4-wire drive plug into the video card's auxiliary-power port, and 2) plug the power supply's square 4-pin auxiliary-power plug into the 4-pin receptacle on the motherboard? If not, do that too.

Good luck with your new system!

Welcome dmckenz,

Did you plug in the 12volt ATX power connector.

Try to boot with only CPU 1 stick of ram and video card
hooked up. You may want to also try to boot up outside
of the case on a piece of card board. Your MB may be shorting
on the case.

You could try 1 stick of memory in a different slot,
(I'm assuming you have 2x 512 for dual channel)

are you hearing any beep codes??

Hope this helps, I'm no expert BTW

Ok so I dragged the thing down to the local shop on my lunch break and the guy hooked it up and said that it was a problem with the powersupply that was included in the case. He disconnected the ATX cable to the mobo and plugged it into the tester and it didnt turn on the light, he then showed me how a good powersupply made the LED turn on. Great, so now Im trying to see if I can just ship the powersupply back for replacement and not the case since they were bundled together. There isnt much info in the manual or website for warranty stuff so I hope the complaint form works. I also hope this is the only problem.

Picked up an Antec PS but I hooked it up and it made no change. I looked and the TK ps came set for 230v instead of 115! Could this have toasted my mobo and video card? If so that must be what the problem is, Im going to try my 5600FX in another rig today and see.

Don't give up just yet. I had a friend whose system ran but would randomly reboot, and what do you suppose the problem was? Yep, PSU set to 220V input. It ran, but couldn't quite run stable with the transformer set up that way. After setting it to 110V it was fine from then onwards. Hopefully yours will snap out of it. Try resetting the CMOS again while the system is unplugged.

I'm also building a new system

Thermaltake xaser3 1000c
Giga-byte ga-7nnxp (nforce2)
2x256 ocz pc3200
an old geforce2 gts
I am having the same problem as you I start the system all the lights go on but nothing onscreen.
I also am not getting any beep codes from the bios. Thanks
