Just put a new PC together today. Used a Q9650, Asus P5Q-E, 4Gb OCZ DDR RAM, 4870 1GB etc.
Plugged DVI cable into monitor and graphics card. Turned PC on, nothing. Checked I was on DVI mode then I got a message saying "No Input detected". This was using a DVI cable I bought as I was told the monitor didn't have one with it. It did, albeit a DVI at one end and HDMI at the other. The 4870 came with a HDMI/DVI adapter so I used the monitor supplied cable and still nothing, so not the cables. I tried the new monitor on my old PC and I got an image on the screen that I expected. So the monitor works.
I then tried using my current GPU (x1800XT) in the new PC. Still nothing. So perhaps the mobo? So to be sure I tried the 4870 in my old PC. Nothing. More likely to be the GPU now instead of the mobo? Then I decided to resurrect my old PC so I could go online and find some help. Uh oh! Now this won't boot. My old monitor saying no signal coming from PC which surely implies static discharge as it was working before I put it in new PC but not after. However the new PC had the PSU in and plugged into the mains.
I then used my Mum's laptop (am using it now) and realised that there should be some BIOS beeps if there were errors. So I plugged the speaker back in so I could listen for any beeps on power up. Nothing. A check of the manual and a successful boot should result in a single short beep. No beep at all. Does sound like the mobo has gone.
The manual also says that if no RAM or GPU is detected then there will be a pattern of beeps. So I remove RAM and the beep pattern expected for no RAM doesn't occur. Same for removing GPU. Sounding increasingly like the mobo has gone. So no BIOS beeps at all on this mobo (successful boot or otherwise) suggests the mobo is definitely gone. Either damaged in some way or I've somehow been careless and somehow caused a static discharge which could have affected the 4870. But for pretty much the whole day the new PSU has been plugged into the case and into the mains so the new case should have been earthed for most of the day. However if there has been static discharge putting the 4870 into my old PC could possibly have carried the static discharge over? And putting my x1800XT into the new PC the same. So that could explain why neither PC will boot and both PCs prompt the monitors to say "No input detected".
The only thing that makes me not believe static discharge has affected my old PC is that it was definitely earthed. So only the 4870 coming over already affected could have caused an issue with my old PC.
I've tried taking one stick of RAM out and booting with that. Nothing. Used the other stick on its on and same result. Took the sound card out and nothing. Reset the BIOS by moving the BIOS jumper over for 10-15 seconds. Still nothing. I also unplugged the Samsung 1Tb drive and the Pioneer DVD-RW drive from their SATA sockets leaving the WD640Gb disk on its own. Nothing.
So after a long ramble can anyone else suggest anything I can do with the two PCs I have to test. My old PC is a 939 so I can't swap the CPUs. I want to do as much testing as I can before I have to RMA anything. If I do have to RMA what should I RMA? The mobo and GPU?
Please accept my apologies for this long post but it has been a long day and I've no idea what is wrong and how I can fix it. I will post this on some other forums just to get as many opinions as possible. If you see this thread somewhere else just reply to the first version you see. :)
