Iv just built a new computer and when i go to power it up the fans come on the dvd drive can be ejected but there is no picture. There is only one beep at the start up also.

The computer parts are

http://www.ebuyer.com/product/130484

Extra Value 550W Gold ATX Silent PSU with PFC and 12cm fan
http://www.ebuyer.com/product/102993

My feeling is that i should of not cheaped out on the PSU which might be the problem not giving enough power to the graphic card but the fan on the card powers up and spins.

Please can anyone help, really not in a happy mood with it not working but really hoping one of you could put a smile to my face. :lease:

the power requirements of the ATI3850 + E6750 arn't particularly high and I would have thought your PSU - albeit not a branded one - should be fine.

I would check all connections plus any additional power connectors on the motherboard and gfx card.
Does the monitor actually come out of standby when you power-up ?

Unfortunately, it could be one of many things not working possibly motherboard or gfx card......

Not to be rude in anyway but is this the first pc you've ever built or are you still quite new at it.
I only ask because one of the first comps i ever built had this problem and when i finally got it going (I had to rebuild the sodding thing) I had done something to the graphics card and it was giving me the 'thread' error, so the whole thing went down hill from there

But it could be a whole heap of things do your harddrives make any noise, or show any activity on the hdd light. Have you plugged the monitor in (if you've ever worked in IT you will know how common this is), do you even know the monitor works etc.

Have you tried plugging the monitor into the onboard vga socket?

i know the monitor works because it is used for my old computer, the hdd light does flash plus i have tried starting the computer without the hdd and it does the same thing. I have built 3 computers so i would say i am fairly new at doing this stuff. There is no onboard vga socket to try. im really running out of ideas but thanks for your help so far has anyone got anyother ideas?

I'm slightly stumped by this problem...

If i were you i would go through the process of rebuilding it slowly and seeing if there is anything i've done wrong.
Sorry I can't be anymore help, but without being there with it in front of me I'm at a loss

Juts my rookie mistake i got so hyped it finally worked i forgot to set the boot order and harddrive was first iv changed it round now
I usually find it best to set boot order to HDD first anyway (speeds up boot times a bit and safer in case you leave a bootable disc in drive) you can always force it to boot from CD when you want to by pressing the hotkey listed in BIOS spalsh screen to specify a one off boot device. Usually F12.

I'm glad you found out the problem

I hope the graphics wasn't new, but i will say this after a few years of building pcs constantly, the only real problem i come across is with the sodding graphics card.

If i can give some advice handle the graphics card with a massive amount of care as they are extremely sensitive pieces of equipment.
