Hi all,

I think I might have killed my computer. I've had my build since last October without any problems, but last night I tried to install some upgrades and only the fans came on. My motherboard hasn't loaded to BIOS or beeped ever since, and I can't get any video output on my monitor. No Dr. Debug display. On first installing the new parts I thought I smelled a very faint metallic burning, so I immediately shut everything off. In the dozens of times I've tried to boot my computer since then, there's been no smell at all. I've been searching for solutions for hours, but I don't have any spare parts to swap in.

The upgrades were an SSD, a DVD-ROM, and some RAM. I was extremely fatigued last night and shouldn't have been doing this, but I haven't had time off from school in months and was excited to finally install the new parts. I made several big mistakes: I was sitting on carpeted floor and did nothing to ground myself (I don't have a wrist strap), the RAM sticks weren't fully inserted, and I never checked to see if the RAM was compatible. There was no noticeable static discharge, but that doesn't mean a devastating one didn't occur.

PSU: Corsair 850W

Motherboard: ASRock Z68 Extreme4 Gen3
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CPU: Intel i7 2600K Sandy Bridge
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

RAM: G-Skill 2x4GB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

GPU: Very old 512MB GeForce 9800

Here are the peripherals I attempted to install last night:
Crucial 128GB SSD
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Asus DVD burner
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Corsair 2x512MB RAM (very old, yes I'll throw it away)

I have not tried to put the latest peripherals back in. I have disconnected all parts possible and still can't get so much as a beep out of the motherboard. I've removed my original RAM and also tried them each one at a time, but not in every slot yet. I'll do that as soon as I'm home. I have reset CMOS with all three methods available with no luck. I inspected my processor for damage and couldn't spot any, but I don't know if that means anything; it could still be the PSU, RAM, motherboard or CPU as far as I know. I'm also going to see if the motherboard is somehow touching the case and causing a short.

Completely reckless of me. Does anyone have any ideas on how to troubleshoot this with limited parts and funds? I'm sure I'm missing important details here, so I apologize if I'm straining anyone's patience -- I'm thoroughly exhausted, have a portfolio to finish, and have been attempting fixes and searching for answers for hours.

Thank you for any and all help.

They even make 512MB sticks of DDR3? And 850 watts for a 9800GT?? Wasted some money there you could have used for RAM.

It is easy to loosen a connnection or improperly (re)seat one.
Also I have had trouble with wies and headers I would have sworn I never went near.

You do not memtion your case. I suspect an older one that makes power supply wire routing a mess. Especially with all the wires of an 850watt power supply.

Obvious checks are the 2x4 EPS Connector and the CPU fan plug. tHE 2X4 MOTHERBOARD CONNECTOR often involves routing which can tug on it when making changes. Some motherboards turn off if they do not detect CPU cooler fan.
Try booting with old RAM. than one new ram at a time. See manual, usually intel motherboards like the RAM in the pair of slts furthest from the CPU.
Ditto the video card power connectors.

Usually troubleshooting involves time and patience or "luck or brilliance".

Trouble shooting outside your case, where it is easy to see and examine connections is the certain way. Adding one component at a time.

Make sure you have a case speaker since if no beeps with no ram points to the board being bad.

Thanks, I did run through this earlier this morning and got to #16, which is why I think that's probably where I damaged something. I just ran through it again to be sure:
(#1, I've been super careful to follow the manual thoroughly; #2, 3, 4, yes; #5, GPU doesn't require a power connector; #6, 7, 8, 9, 10, yes; #11, no bent pins; #12, not using an after-market cooler; #13, yes; #14 and 15, everything's good here; #16, no, I definitely did not take precautions here last night; #17, installed the speaker this morning; #18, definitely; #19, 20, 21, yes; #22, been trying the integrated video port as well, yes; #23, earlier today, I thought so, but I will run through this and check every connection again to make absolutely certain)

Definitely no beeps with no RAM, but then, I can't be positive that the speaker's working since I only put it in after killing the system.

Actually, it's a 9400GT, I just checked. It was from a friend to get me started. This build was intended to be long-term upgradeable, and I got the power supply for eventual SLI configuration.

Sorry, the case slipped my mind. It's a Rosewill Challenger:

Thank you so much! I'll definitely run through and recheck all of those a little closer and try the old RAM. This motherboard prefers RAM closest to the CPU and pairs them (1,2,1,2), skipping a slot instead of being side-by-side. I'll try the other configuration though.

Breadboxing this to troubleshoot is a good idea, thanks.
