New comp just won't work!!

jmc160

I'm busy building a new computer for Windows Home Server and I'm getting really annoyed with it now...

I used an old computer as a bit of a donor, but due to some issues, most of it has now been replaced. It's got new hard drives, cables, CPU, and now a new motherboard cos of issues getting it to build on the last one.

The new motherboard came, and i was most annoyed to find it had a 24 pin power connector. I bought an adapter.

Now the damn thing won't even power up!! :mad:

I've tried using different case buttons, a different PSU, but I'm out of ideas. The MB is getting power as it has a green LED to tell me so.

I'm wondering if tere's any minimum requirements for the power supplt on these e-ATX mobos... Anyone got any ideas?

I'd give up and enrol in an art class instead, its not for you is it?, mind you, you have not given up and all those new parts too....can you go back to basics and why on earth did you not get here sooner? Start again with the original bits and pieces, what issues did you have...?

Before changing the mobo, It would POST but now boot to the disc. The mobo had a history of issues so I was replacing it anyway. The other new bits I was buying anyway. The only bit that has been replaced as a repair is the mobo.

Are you getting any beeps ?

The green light on the mobo is probably a good thing

>It would POST but now boot to the disc
Did the bios report the drive?
Is the drive bootable does it have an OS installed, partitioned and formatted Is the drive in the boot priority of the bios and is the drive a sata are the drivers installed, if a pata is it cabled up as master / slave with the optical drive?

Sorry, that should have read "it would POST but NOT boot to disc, as in the Home Server installation DVD. It would run through to the memory test but just stop. Couldn't select a drive, pull up the BIOS or anything. That, plus the history of the motherboard, is why I replaced it with a brand new one.

The drive (HDD) is not bootable because it's brand new and unformatted. I don't know if it's in the boot priority because the computer won't power up.

Everything is cabled up properly, IDE opticle drive, SATA HDD, PU connected up using a 20-24 pin adapter, new CPU all fitted and fan cabled correctly, buttons and LEDs all conected properly, etc. etc.

Have you connected the four (or possibly eight) pin power connecter in the vicinity of the CPU? Older ATX boards used a 4 pin plug and newer boards use an 8 pin plug.

This plug supplies +12V to the CPU and without it the board will not boot.

Yep, all plugged in.I've just bought a new PSU for good measure, so I'm hoping an uprated one will make a difference. Maybe the current one just doesn't have the output or something...

The only thing to change if that doesn't work is the case!
