[HELP!] Computer won't boot after cleanup

post #1 of 3
Thread Starter 
So here's the deal. I just recently bought my 2nd GTX 680 to SLI on my build. I decided to do some general cleaning since I'm opening it up anyway. I disconnected the desktop to all the cables (PSU, Kb/mouse, etc) and opened up the side. I gently dusted all the visible dust I could see with the duster first (take note that there are no exposed wires in the case as everything is routed through the back). Then I took out my graphics card and did some more cleaning to the board as the card was previously in the way. I also took the opportunity to set my rear case fan to blow out instead of it's previous blow in because I will be adding an additional 2 side intake fans and I suspect the rear intake to be the main cause of the dust (the 2 fans in front have filters and the top RAD fans are set to blow out). I had to open the rear side of the case now to reconnect the fan and to route the additional power cables for the 2nd card and additional fans, I did not touch anything else. Having cleaned everything as best I could with the duster, I put back the video card as well as the new one and added the SLI bridge and power connectors.

At first the computer turned on without any issues, I didn't have to reinstall the NVIDIA drivers as the 2nd card was being detected perfectly and so I set up SLI and 3D Vision accordingly. I tried out 3D Vision with Assassin's Creed 3 and all with no issues. I closely monitored temps on all components especially the video card and they were both in the early-mid 70's and perfectly fine. I stopped playing and started browsing when suddenly the desktop died, no BSOD or any driver failures or anything. It started to turn on again and I was able to get to Windows again so I checked event logs but got nothing but an unexpected shutdown log. It then turned off again without warning or reason shortly after.

I proceeded to then conduct troubleshooting but now the computer totally won't boot, the display doesn't detect it, the RAD is on, the video cards and all the fans are turning but nothing happens, don't even get a debug error from the mobo. At best I get a "00" debug error which is "unused" according to the manual. Very rarely it would boot and when I check everything is fine but then it'll shut down and attempt to start up again. The following are the steps I tried but so far I get the same result = display not detecting and getting the "00" debug code:

1. Took out new card and tried booting to old setup
2. Cleared CMOS through button and jumper
3. Took out both video cards and connected to integrated
4. Reseated/reconnected RAM, Video Cards, all power cables from PSU and board/card, all SATA cables
5. Removed all but the RAD's fan connectors
6. Blew on all the slots and made sure everything was clean

I did notice that 1 of the RAD's fans would not run when connected to 1 of the CPU_FAN pins. The last step I can do is to remove and rebuild the entire thing but I'll have to do this on a weekend and right now I don't have enough time for it. My suspect is that there is a grounded connection somewhere which is causing the issue, but doesn't explain why it sometimes boots up without any issues. It could also be a faulty motherboard or a faulty powersupply. I'll have to borrow another PSU from a friend to try it out.

Sorry for the extremely long post, just want it to be as detailed as possible. The rig in question is the "Prometheus" rig in my sig. Please feel free to make any suggestions as this is really starting to bug me as everything was fine before I did the cleaning and now I can't get it to work. I would also hate to have to buy any new hardware as the rig is only 1 year old (and out of the 1 year store warranty) and a big hassle to RMA anything.

Thanks and cheers.

Have you tried using only one ram chip in the second slot?

It sounds like it's not passing POST.

Did you at all fiddle with the cpu or socket?

Didn't fiddle with the CPU at all. Haven't tried running with 1 RAM stick. I plan on disassembling the entire thing and running it without the case on but it's really a big hassle. I'm starting to suspect a faulty power supply.
