Re: building a pc
in fairness a 500 watt decent psu should do the job. In tests ive meassured my machine ( higher spec and multiple drives with a 5870) and under load the draw has been less than 400 watts. For it to be the PSU imo it would have to be faulty not underpowered

Re: building a pc
Install the MINIMUM components. i.e. One single stick of ram (in the correct slot, read the manual that came with the mobo). Make sure the CPU is in the slot properly the correct way around (check the arrow on the corner of the cpu corresponds to the place on the mobo). Make sure all PSU cables are connected to the various power points on the mobo (ATX 24 pin, 4/8pin, etc). Then install the graphics card and ensure it has a PCI-e power connector connected to it.
Then DO NOT install anything else like HDDs, CD/DVDRom or anything. Just try booting the Computer. What happens? Do you get any activity when observing the computer with the case door/side panel off? i.e. Does the CPU fan attempt to spin? Does the PSU come on and the fan start? Do any LEDs come on or beeps from the mobo? Obviously ensure that the monitor is connected with a VGA/DVI cable to the graphics card you have installed. ---------- Post added at 15:22 ---------- Previous post was at 15:19 ---------- If you could also post a picture looking inside the computer and how you have it all connected, this might help. |

Thanks for the reply Damien ,the cpu power lead is only a 4pin ,the psu lead does have the option of another connection 8pin but it is not needed .The mobo supply is 24 pin and all connected ,the gfx card has it's own supply using a pcie connection to the card (4 pin).I have come to the conclusion that it is a faulty board mainly because of the issue with the dvd drive cutting out as soon as the IDE is connected so i have ordered a new one from novatech a different board as the service from ASUS is diabolical ,so i ordered one of these this afternoon to arrive tomorrow GIGABYTE GA-880GM-D2H AMD 880G (SOCKET AM3) MOTHERBOARD ---------- Post added at 15:48 ---------- Previous post was at 15:46 ---------- Quote:

Re: building a pc
Can you explain what you mean buy "the dvd drive cutting out as soon as the IDE is connected". Explain the process/steps you took. What are you defining as "cutting out" ? Surely you cannot test the IDE drive as you cannot get the system booted? You are not making a lot of sense. I mean it sounds like you are booting the system and half way through boot you connect an ide cable to the dvd drive? What are you expecting to happen?

I would suggest you forget about the DVDRW drive for now and focus on finding the fault. So...with CPU/RAM/GFX installed, you press the power button on the PC (I assume this is wired into the motherboard so you can power it on?) you get nothing? No fans spinning up? No LEDs? Have you tried reseting the CMOS? DO you know what is involved with this? You could also try swapping out the ram for different sticks. Failing that, I would try your spare power supply just to see if you can get an output on the screen and POST (Power on self test). Do you not get any LEDs or beeps on the board during boot? Some motherboards will beep or present LEDs during post do help diagnose the fault. i.e. Say 1 LED = CPU found, 2 LED = Ram found, 3 LED = Gfx found, 4 LED = running post. It could do something like that with beeps instead. |

Re: building a pc
its the mobo mate
saying that I would try the different psu just in case |
Re: building a pc
You could try the GFX card in the other PCI-e slot. I assume you have it in slot 1 currently? That motherboard does NOT have what we refer to as "onboard" Graphics. This means it will not have a connection to a monitor natively. You HAVE to use the graphics card (the 5770 you have bought) to output to a monitor. Is it possible you have not set the monitor to pick up the digital (DVI) signal or vice versa with VGA analogue? You should try setting the monitor to different inputs manually incase it is not auto detecting it correctly.

OK let us know how you get on

Re: building a pc
SUCCESS
my son now has a AMD PhenomII black, gigabit GA-880-D2H mobo 4 gig corsair dual channel ram with a ATI radion HD5770 GFX using a HD portable and a vga 15" monitor The original problem as posted earlier was not the board it was the processor ,when the stuff was delivered i was at work and my son put the processor on the board and bent a pin causing one ram slot to stop working and the peculiar problem with the DVDRW ,but lucky for me the pin was the one next to the triangle so i was able to straighten it and now it works .It boots into windows in under 30secs is blisteringly fast and whisper quit So thank you to everyone who assisted :tu::tu: |
Re: building a pc
you were lucky it didnt snap
Glad its sorted now though |
