So I built my first PC in 2006 and ever since about 2009 or so, I've had this random problem where when I turn on my computer, the fans all start up (including CPU fan) and my graphics card's fan runs full blast instead of starting fast and then leveling out. I get no POST, I get no display, and I get no clues to fixing it. It used to be that it would just start working if I would wait or if I fiddled with the cords (or banged on it in frustration). Then it was fine for a while.. and by a while I mean years. After the problem started up again, I then I discovered that if I fiddled with the video card (reseated it or even just wiggled it a little), it would fix the problem fairly consistently and I kind of wondered if the video card was touching the case in some way and that was the problem.. that I have since ruled out by removing the motherboard from the case completely. Then I also found that removing a stick of ram would also fix the problem indefinitely. But then on a whim, I decided to put that stick of ram that I had removed back in and it was working fine for a long time. Then I moved to a new room in my house and the first time I tried to boot it, the problem came back again. So I fiddled with it a little and checked to make sure all the cables were tight and everything was fine and I got it to boot up and it worked just as normal. Then I made the mistake of turning it off and ever since then, it's been giving me the same problem. I have tried everything I could think of. The only thing I haven't done is tested the PSU because I am unsure how to do so and I wasn't sure if it was a possibility that the PSU has gone bad.
Today, I removed everything but the bare essentials from the motherboard, and I even just now removed the motherboard from the case and have been starting it up that way by shorting the power pins and the problem hasn't changed. The only thing I kept plugged in was the power and the CPU+fan and even that plus one stick of ram and still nothing. The first time I tried this, it seemed to boot up normally (video card fan speed was normal) but then I turned it off to plug in the HDDs and it's back to square one. I am completely at my wits end with this. I proclaimed it dead some time ago, but the inconsistency and the sheer length of time that I have had this problem intermittently has led me to start trying to figure this thing out again since I can't afford a new system at this time and I don't want to waste this system if there is just some dumb little problem or some little component that I could fix if I could find out what it is.
My next step: I recently removed the CPU heatsink and fan and noticed that the thermal paste is completely dry so I removed it and I'm planning to get some more to replace it, but I don't really think that was the reason it's not been giving me this problem.
Here is my system..
MOBO: ASUS P5N32-SLI SE Deluxe LGA 775 NVIDIA nForce4 SLI x 16 ATX Intel Motherboard
Video Card: XFX PV-T71G-UDE7 GeForce 7900GT 256MB 256-bit GDDR3 PCI Express x16 SLI Supported Video Card
PSU: Thermaltake TR2 W0070 430W ATX12V v2.3 Power Supply
CPU: Intel Core 2 Duo E6700 Conroe 2.66GHz LGA 775 65W Dual-Core Processor
RAM: CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048
OS: Windows XP
If anyone has any ideas of how I can proceed from here or at least just give me a clue of what is going on, I would be forever in your debt. This has been driving me nuts for years and I have not been able to pinpoint what is going on. Don't get me wrong, I would love to get this system running again, but part of the reason that I want to figure this out is just because I don't know what's going on and I really want to.
By the way, I did read the sticky pertaining to this problem before posting this.
