3 Weeks, No Video, No Post Beep, No Results -_-.

dbrown1986 · May 17, 2013

First off, I have read the no post/no signal thread up and down and nothing there seems to help me.
Secondly, I did not know the best place to post this so I figured GFX forum would be alright since I am getting no signal to my monitor.

Okay so going on three weeks my PC has not displayed a video signal. I have been through EVERYTHING that I can think of to get it working and am at my wits end.

At first, I was told the motherboard may be bad since both the onboard and PCIE of that board were not working, so the Motherboard and PSU have been replaced, I have ordered a replacement CPU that is on it's way, I did have both the old PSU and the current Video Card tested and they both passed all tests. Here's where it's sitting at the moment:

Mobo: MSI P43-C51.
PSU: ThermalTake 600W (Bought today).
RAM: 8GB (4GBx2) SuperTalent DDR3-1066.
Video: MSI Radeon R5770 1GB DDR5, 128-bit, 850cc/1400mem.
HDD: WD Cavier 500GB Blue.
Bluray Drive / Bluray Burner.

System Speaker (which does not post ANY codes, not even a long beep).

I have checked ALL parts thoroughly except for the CPU and I've about had it. Really want to pitch the thing over a cliff now since it was working just fine three weeks ago and now nothing no matter what I do. The CPU does sound like it's making some noise but that might be the HDD needle that I am hearing.

Any thoughts?!? Maybe a dead CPU? Would a dead proc cause no beeps?

no i dont think a processor would do that do you have the manual on/off switch turned on on the back of the psu? you might have checked that

Fulgurant · May 17, 2013

Dead CPUs are pretty rare, but hey, it's possible.

Do the fans power on? Did anything change three weeks ago, before you noticed this problem?

Here, actually, go through this checklist: http://

dbrown1986 · May 17, 2013

Yeah the PSU is powered on in the back and the electrical switch is on 115. Yes the fans spin up, and that is the checklist I was referring to above. The only thing that happened three weeks ago was a rigorous cleaning after moving out of a very dirty house.

dbrown1986 :

So the PC was working fine, then you moved/cleaned it, and afterwards it stopped working?

And you've since replaced both the motherboard and the PSU, with a new CPU on the way. Unless you accidentally unplugged something and/or forgot to plug something when installing the motherboard, it's hard to imagine that your problem could be anything other than the CPU, at this point. Unless both your monitor and your system speaker both decided to break at exactly the same time, which ain't likely.

I know it's not good news, but it sounds like you gotta wait for that CPU.

Fulgurant :

Well I just got a new HDMI cable and a new speaker yesterday, so I know it's not them, and I have checked over all the connections. I just thought about it and I haven't tried pulling the Reset SW. I will do that and edit this post if it works.

EDIT: Pulling the Reset SW changed nothing. Still no video or POST.

EDIT 2: On a whim, I pulled the CPU and found thermal paste fingerprints on the underside where the pins make contact, so I cleaned that off, could that have caused a short or surge of any kind?

Fulgurant · May 18, 2013

dbrown1986 :

Yeah. Based on the timeline you described and the steps you've already taken to troubleshoot, the only thing I could guess was that you bent a few CPU pins while you were cleaning the machine three weeks ago. Thermal paste on the pins can't have been good either, though. Same result.

We won't know for sure til you get your new CPU, but at least it's a working theory.

Sorry to hear about all your troubles, man. Please keep us posted.

Fulgurant :

Yeah, this is the new mobo and I just checked the pins last night with a magnifying glass. They are all upright and free of any signs of TP so the thermal paste that was on the CPU did not make transfer yet, that's good. This new CPU coming in the mail should do the trick no doubt, just have to be careful this time not to apply too much TP. It might be a week or so but I will post an update once the new CPU is in.

The real question I have been trying to get at though is if it is typical for the CMOS to not post any beeps whatsoever if the CPU is bad? That would give me a definite answer, even though everything else has checked out fine.

I honestly hope I haven't done anything to hurt the new MOBO.

dbrown1986 :

Dunno about "typical," but yeah, zero beeps seems likely with a bad CPU: http://en.wikipedia.org/wiki/Power-on_self-test#Original_IBM_POST_beep_codes

I hope the mobo's ok, too. Will keep fingers crossed.

UPDATE: Well after four long weeks, I finally got my computer to boot. It wasn't the mobo (aside from the fact that me and my bro bent the pins on it), but I got a new one, it wasn't the power supply, but I got a new one, it wasn't the CPU, but I got a new one, and after replacing parts and thoroughly testing all the others, it still didn't even post. I was lost at this point but then realized after a bit of googling that the front panel connectors might have been placed on backwards (which would cause a short) as the computer was not getting enough juice basically. I corrected two which were backwards (which me and my bro again setup and I thought we had put them on correctly), this time it still did not post but sounded like it was getting more juice. So I refered to the owners manual and found that there was a feature on the new motherboard (DOT Overclocking) that controlled the FSB of the motherboard and components, the manual specified the default settings, which the board was NOT on, so I set them to default, and VOILA! It BOOTED!

Now, I'm not entirely sure that internet (or spinning tunes for that matter) is going to be possible as I will be on wireless and the router is down the hall in another room, but; alas, we shall see. I have a lot of testing to do and the new mobo requires that the OS be reinstalled before I can do anything...

On to backing up important files from my previous OS install...

THANK YOU ALL SO VERY MUCH for enduring, showing an overwhelming amount of patience and being insightful and thoughtful, and straight to the point with AWESOME suggestions, I don't honestly know why I didn't think of a short in the first place... -_-

Okay, got the new CPU today and still the same result. No post beep, no signal. I'm thinking I should take it into a shop, it's got a new mobo, a new CPU and a new PSU so the only thing I could think of is that the case is shorting it somewhere... I'm so lost. I've gone above and beyond and done everything that is needed (within my tech level, which is pretty good); so I'm guessing it has to be a short or something, but where?!?

I believe the speaker and some of the FPC wires might be connected incorrectly, which if that is the case then it is very well possible that it's causing a short. It's almost 2:30 AM here though, so I will try this tomorrow and if that doesn't work then I will take it into a shop.

Wow, sorry you went through all of that, man -- but glad to hear that you (appear to have) finally found the problem!

Thanks Fulgurant! ^_^
Just happy to have my baby back

and now I have an extra CPU just in case
