I am in the process of a new build which ran into an issue that I hope to have fixed tonight but want to check with the community. As a warning the story may get long. But any comments to help will be appreciated. My old build which I originally assembled in February of 2005 CPU: AMD Athlon 64 3500+ upgrade to AMD Opteron 165 Denmark in 10-2007 MOBO: MSI K8N Neo4 Platinum nForce4 Ultra socket 939 PSU: Antec NeoPower 480W HDD: WD 200GB (failed 10-2008) upgrades and additions to 3 – 250GB HDD RAM: 2 - CORSAIR 512MB 184-Pin DDR SDRAM DDR 400 (PC 3200) Upgraded to 2 - CORSAIR 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200) in 2-2007 GPU: MSI NX6600GT-TD128E GeForce 6600GT 128MB 128-bit GDDR3 cooling fan failed and cooked itself in 2-2007 – upgraded to XFX PVT71PUDD3 GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16 Optical Drive: LITE-ON Model SOHW-1633S DVD+R DVD Burner E-IDE upgraded to SAMSUNG Model SH-S203B 20X DVD±R DVD Burner SATA in 10-2007 No name case with decent cooling and modified for improved cooling History: About 2 months ago my computer started to not come back from sleep mode. The power button and reset button did not work either. There was a fan working harder than normal and there was an intermittent beep coming from the case speaker. After shutting it off via the PSU and letting it sit a minute I turned it back on and it booted right back up with no issues. After a week of this recurring near every time I walked away from the computer for more than a minute, I dismantled and cleaned everything I could looking everything over, changing up my power configuration, and rerouting the wiring. I noticed in this process that my Northbridge heatsink fan had failed at some time but could not get any of the screws out to remove it. I popped the fan out of the heatsink carefully but left the heatsink in place. I put everything back together and it booted right up. I went into bios and reduced my overclock which was fairly minimal to begin with. Everything worked fine again for about a month and then the issue started again. I figured it was either my PSU or the motherboard since the Northbridge was fairly certain to have experienced some heat issues over time. Finally the day came when I had no video when I turned the computer on I could hear it POST and then it gave a long beep. I was frustrated from work and other things going on so I let it sit for a while and when I came back later it turned on and fired right up. I shut it down after I was done doing what I wanted to do. The next day I was not so lucky, same issue but now seemed to be permanent, no video on the monitor to show me an error. I tried diagnosing the beep code and even installed the bracket with the lights to help diagnose POST code errors but it did not make any sense. I figured the MOBO was just done. I have had the itch to upgrade for a while (quite a while) and with the 955 out I was ready to bite. But I first had to look to see if I could find a cheap 939 board that would fit my needs (fiancée who does not understand hobby). But none are to be found for any decent price. Present Issue: So I started pricing components and figuring out what I needed, wanted, and make it somewhat future resistant. Came down to the details in my spec, with an exception, I thought my GPU was good the 7900GS and figured I would wait till DX 11 to upgrade. I kept my hard drives and optical drive as I am sure they are fine. I put together my new build Sunday night everything was going great checking things over changed up a few things for wire routing and such, it looked good. Went to boot for the first time, fans spun up could hear the hard drives quietly working but what is that loud fan? And why do I have no video?... I shut it off and tried the other DVI port same thing, shut it off tried a different cable, same thing, shut it off tried a different monitor, same thing. The Antec 300 does not have a speaker so I did not get any POST code beeps at the time. I figure my problem may not have been what I thought… It may have been a strange death of my video card. I ordered a new card (HD 4850 in my specs) yesterday and last night I hooked up a case speaker to the mobo cleaned up the contacts on the card unhooked the hard drives and tried again same thing but the POST code beep was long with some warbling near the end so I don’t know if the long and short are so close as to be indistinguishable or what? I tried a few other things but never got any video on the monitor or a different POST code beep, even when I booted without the card in. On a cool note I found out that my new pc will be near silent without that GPU fan spinning up. I will be trying the new vid card this afternoon. I am getting quite anxious and am to the point where I need my home pc working again ASAP. I am dreading that I may have received a faulty part which I know happens. Any comments or suggestions? Is there something I am missing or that I should try first? You have my thanks for any help offered.
