Hi guys, attempted to put together a computer for the first time last night. Everything seemed to go well and I was extremely careful with each individual component and made sure they were all fitted in the right places etc. Came to booting it up and there's no display output at all. Tried onboard and GPU outputs. Tried stripping components to bare essentials. Tried switching monitors. Nothing works. All the fans are working, mobo lights are on e.t.c

What could it be? Also, the PSU is more than adequate for the components that I have.
 
Will be able to get photographs later. Building a wall in the garden at the moment :P

I believe that all the mobo stand offs are fitted correctly, even drew a diagram to make sure that they were all in the right place.

How do you turn on the pci-e graphics from within the BIOS? I can't access the BIOS because there's no signal to the monitor.

Cheers for your help
 
Have you provided power to the GFX card if it needs it?

Have you got the extra 4/8pin ATX plugged in near the CPU socket?

Try a clearCMOS.

I bought the Corsair 430w 80 plus PSU which doesnt have the 4pin ATX power connector for the plug near the CPU. It does have the 24 which is plugged in to the MOBO.. Is the 4/8 pin ATX essential?
 
the MOBO has a 4pin slot next to the CPU. No obvious 4 pin connector coming from my PSU, although there is one with more pins. So your saying attach the one with more than 4 pins to the 4 pin socket?
 
Yep, all the hardware seems to be working fine now and my computer posts with a single beep when I turn it on. Thanks for the help on that.

However this isn't it. Started installing Windows XP last night and during the install I got a BSOD with the message :mad:

Irql_Not_Less_or_Equal

I've researched this and its apparently something to do with incompatible hardware and drivers.

Does anyone know anything about this bsod, and if so way of avoiding it and installing Windows?
 
tried clearing CMOS. No joy. Part of me feels like its the old Windows XP copy not compatible with current hardware.. could this be true? Another copy of Windows is the last option I really want to get to. Anything that can be done in the BIOS that might resolve it?
 
not that I'm aware of. The only options were to format the HDD/create partitions. Then install it. Could there be an option in the BIOS for IDE or AHCI?

The installation basically gets to the 'Installing devices' screen then gives me the BSOD.
 
ok thanks footman. Which should I try and install it as? IDE or AHCI?

The BIOS is UEFI. Should there be an option in it to simply change?
