New System

[imported_foxeh]

Hi, this is my first post on these forums but I could do with some help and guidance.

I recently decided to build a new machine and decided on these parts.

ASUS A8N-E Deluxe
AMD64 3500+
Crucial Ballistix PC4000 (2x512)
Seagate 160GB SATA HDD
Antec NeoPower 480W PSU
XFX GeForce 6800GT
Sony Daul Layer DVD-/+ RW 16x
LG DVD-ROM 52x
Acer 17" TFT monitor
Thermaltake Armor VA8000SWA Case.

I have previous experience upgrading/building machines so I was confident I could build it.

I got everything set up..conneted the EZ-Plug, the XFX was abit of squeeze because of the mem slots but nothing too serious.

Booted, all the fans started spinning..but I got "No signal" on the monitor. Checked the connections to and from the monitor, made sure the card was all the way in the slot and I still got the error.

Decided to use the second DVI port on the card, still no luck. The decided to use the DVI connecotr I got with my ASUS x800Pro (AGP) and the same again.."No signal"

At first I thought it was the monitor but when I hooked it up to my other machine it worked fine. I contacted Komplett.co.uk where I ordered from and was granted an RMA to return the card as they said it might be a faulty card. Decided to take a trip down to a local PC market and bought an MSI NX6800GT. Hooked that up, "No signal" :'(

I tried 3 other HDDs (1 empty,2 with data on). Another set of RAM and still the error. SO this leaves the actual board, the PSU or the CPU. I doubt it would the CPU so It's either the board or the PSU.

Having read some other threads, it looks like it could be the PSU struggling from a cold boot? Anyone who has any info/help for me it will be gratefully appreciated.

I just wanna play with my new system, is that too much to ask!? :''(

foxeh.

Try taking everything out before you RMA anything.

Try booting with you motherboard, cpu, hs/f, videocard, ram, and powersupply only. Put your motherboard on a piece of cardboard (or better yet, a foam pad that came with it) and put it on a wooden table. Be careful not to shock it with static electricity when it's outside of a case like this.

These are the components you need to get a post.

Doing this will make sure you don't have anything getting shorted out on the case.

You can turn the computer on by shorting out the two pins on the motherboard that the powerswitch connects to. You can use a screwdriver to short out the pins for a second and the computer should turn on.

If you still don't get a signal to your monitor, try taking the cpu out and reseating it (sometimes this can help). Make sure you take out everything and reinstert it. Try the sticks of ram individually to see if one of them could be the problem.


Don't hook up anything else (hard drives, floppy, optical drives, soundcard, etc.) until you get this working.

EDIT: oh, and reset CMOS and see if that helps you out.

 

[thunderroller]

yes you should reset the bios

If you could, try 1 stick of ram at a time, and if possible , try a different stick maybe from another computer?

Right. Ive just tried with CPU, RAM and GFX card only, still no luck. Tried with one stick in each of the four slots, one which I have bought for the machine and one from my other machine, still no luck.

Reset CMOS, still the same. Im gonna try my spare PSU, see if that works, worth a try
:/

Just tried another PSU (Q-TEC 20pin) and still no luck.

Could it just be a faulty PCI-E x16 lane?

Plug in some powered speakers or headphones to the rear audio-out jack and does the speech-diagnostics say anything?

 

[imported_foxeh]

No, I dont even get a beep when booting either

1) did you try the suggestion of testing the motherboard outside the case on cardboard yet, with just the bare essentials. No keyboard, no mouse, no PCI cards, no drives, no extra case wiring besides the Power button's wire.

2) as a point of fact, make sure not to plug and unplug your DVI cable while the monitor or computer are powered.

3) if your video card has a fitting for a power cable direct from the power supply, make sure that's plugged in, of course

Thanks for the suggestions so far, Ive tried em all but to no avail, there must be a fault on the motherboard as eveything else works on a completely diff machine and the fact I bought two 6800GT's from different companies counts out the actual gfx card being faulty.

Think Im just gonna have to return it, I have tried everything suggested on here and I cant see there bein much more for me to try. Think ill change to an MSI Neo4 if I am able to return the ASUS board.

Thanks for your help guys, appreciated

Yeah, at this point if it's outside the case and you're already tried 2 videocards, 2 powersupplies, and both sticks of ram individually, it's almost certainly either the motherboard or the CPU.

Good luck.
