New PC won't start

[Sincerity]

Hi there, i've just bought a new pc and installed all the components with the help of my friend. The problem is, the pc doesn't start or the screen won't blend in. The components are as follows:

- AMD Athlon64 X2 4400+ Brisbane 65 nm 2x2.3 Ghz
- ASUS Crosshair nForce590 SLI
- 2048MB Corsair PC2-800 DHX Dominator CL3 KIT
- 500 W be quiet! Straight Power
- G320P XFX 8800GTS 580M XT 320MB
- Western Digital Raptor 150 GB

Thx 4 help!

Edit: by the way, my friend meant, the mainboard is the cause of the problem, because it's not supporting the processor. is that right?

Re: New PC won't start

Not sure what you mean by "screen won't blend in", but...

According to the Asus website, that board should support the A64X2 processors, but there is a BIOS update that came out on 10 July that added new processor support, so this may take care of your issues. At least it is worth a shot.

I'd also be a bit concerned with a 500w PSU with that video card. May or may not be an issue, but it could be some cause for concern.

It should post/boot no problem with that motherboard. Something is either not seated properly or a part is DOA. That **** power supply is not helping anything at all either.

Re: New PC won't start

Hi there, thank you for the replies.

@Darthtanion: Sorry, i mixed some german in it... i meant, "the screen won't show anything, it remains black". When I push the Powerbutton it starts to boot up (i think), but there's no screen.

@casecutter: "Something is either not seated properly or a part is DOA. That **** power supply is not helping anything at all either."

What's DOA? And why doesn't that power supply fit in? In the shop they said, the power is alright, the voltage is at 30 amp / 12 volt, it should be ok with the VC.

Edit: They even wanted to sell me a 450 W PSU -.-

Re: New PC won't start

are you getting any beeps, error codes or messages?

remove/disconnect as much hardware as possible, ie disconnect cdrom, harddrive

reseat all cards (don't reseat the cpu yet but do that if you have to).

if your not getting any error messages at all - points towards cpu issues

Re: New PC won't start

Hi there,

there are no beeps, so its heading to a CPU-issue. It just beeps, if we're disconnecting the VC and start the PC.

Thanks 4 help! Let's see, if the people at the shop would update the bios for me.

Re: New PC won't start

Trying the bios update will rule out the CPU. I know my PC started straight up with the Brisbane, and most motherboards will but that doesn't rule it out either.

As for the power supply, I am just against non brand name units and atleast it has a somewhat strong 12V+ rail. The wattage rating is meaningless really since most off brand power supplies are very overrated.

DOA = Dead On Arrival meaning it was dead before you even got it. I almsot wouldn't be surprised if the CPU was toast.

Re: New PC won't start

hi,

thanks for the post.

from the looks of it, it's starting. they tried it at the store and it's working! the main problem now would be the tower, because we haven't used any plastic-rings for the distant pieces of the mainboard. i think it's beeing caused by a short circuit which occurs between the screws and the distant screws. I'll reply again, if it's not working. thanks for your suggestions.

Which CPU should i use then? i thought "be quiet" would be a good brand.

Re: New PC won't start

FYI... pretty much all modern motherboards have small metallic built-in grommets surrounding the mounting hols so short circuits are not a common problem. I seldom use them anymore and don't have shorting issues.

hi,

OCZ, Silverstone, Antec to name a few. Basically stick to the major brand names and don't cut corners on price. The PSU is one thing that you truely get what you pay for.

Re: New PC won't start

the PSU was pretty pricey... like the enermax liberty. And i'm always looking at reviews and tests by magazines. Be Quiet! managed to get a superb score.

Still, yesterday we tried to boot the pc by not putting the mainboard into the tower. It worked ^^

So because of that we concluded the above mentioned situation and solution.
