no video signal

[iTWoRxbRo]

i just recently built a computer and when i tried to boot it up, the monitor wasnt getting a video signal. i have tested the RAM, video card, power supply, and hard drive on my current machine and they work flawlessly. i had no way of testing the motherboard or cpu seeing as how my computer runs on AMD and this new one is Intel, so i RMA'd the cpu and motherboard and even with the new motherboard and cpu the computer still will not give a video signal. the power and hdd leds light up and all fans run, but the motherboard is supposed to have a RAM led and i dont see any led that is lit up on the motherboard. any ideas?

MB PT800 GA-8VT800-L GIGABYTE

POWER SUPPLY|ANTEC SL350 350W
CPU P4/2.4AGHz 533M 478P/1MB
DDR 512MB|DDR400 CL3 PC3200
HD 60GB|MAXTOR 7200RPM 6Y060P0

I'll look into this. Any particular reason you're buying that 2.4A and not the 2.4C? The 2.4C offers wider motherboard support, faster 800MHz FSB, and Hyperthreading, plus it uses the Northwood core that usually performs better than the new Prescott core at a given frequency.

While I'm getting your manual downloaded, check out the first link here and that is a Rich Text Format document with some troubleshooting ideas for you. I've confirmed that your board does accept 2.4A Prescotts with any BIOS version, so you can skip the first section where your parts are incompatible/poor quality.

Hang in there

Is the bios reset jumper in the "normal" position? Is the aux power connector plugged into the mb?

this computer isn't for me; it's for a friend who wasn't looking to spend too much money. he just wanted a computer that could do the basics but wasn't too far out of date.

the bios jumper is in the normal position and aux power is coneccted.

Hmm, well for a value system he/she should've gotten an AthlonXP I assume you have your reasons for picking Intel instead (owner's bias or whatever), but if you need an alternative, an Abit NF7-S with a 2500+ would be sweet.

Anyway, I downloaded the manual for that board to check it out. I don't see any obvious stuff jumping out at me. The RAM LED is in the extreme upper-right corner of the motherboard, and if that isn't lighting up, maybe the DIMM(s) are not getting fully seated. Also try each of the DIMM slots.

Beyond that, the next thing I'd do is to put the motherboard on its cardboard box and set up the barebones benchtest setup like my troubleshooting document suggests. Motherboard, CPU/heatsink, video card, one memory module, power cables. Plug in the keyboard and make sure it's in the keyboard port, not the mouse port. No drives, no case wiring except the Power Button switch. If it won't work like that, and you've verified all the parts except the CPU and motherboard, then my inclination is to think there's some sort of issue between this motherboard and Prescott-core P4's, whatever Gigabyte might think. You could try unplugging it, taking out the CMOS battery, moving the Clear CMOS jumper for 15 seconds, then putting it back, replacing the battery and powering on again, too.

Good luck!

yea that does sound sweet seeing as how i have an NF7-S along with a 2400+. im just going to buy an amd processor and motherboard, i give up on that intel pos. thank you for all of your help.

I'm an AMD fanboi, so this may be heresy to some...

But I can't see giving up on an already purchased Intel rig because of this.

Reset the BIOS via the jumper. Remove all cards and memory. Reseat memory and vid card. Try again. If you're using a KVM switch, wire the monitor directly to the vid card. Doesn't that mobo have onboard video? If so, pull the vid card and use the onboard. You may have to go into the bios to tell it that you'll be using the AGP port. Some BIOSs are stupid. :|

Of course, AMD would be much better...

ive already tried all of that.. ive disassembled and reassembled the machine about 3 or 4 times. there is no onboard video either. ive tried everything i can think of and everything that everyone else can think of.
