Black screen of death :( Help!

ICIT2LOL · May 30, 2014

May I put in 2 cents worth?

For seeing what the volts are on the PSU use HW Info http://www.hwinfo.com/download.php < download the right bit version. close the right hand window > click on sensors > scroll down to where I have scrolled in my pic

If you are going to look at those caps PLEASE be VERY careful the large ones can hold a lethal charge

For another test try this

HARD DRIVE SURFACE TEST

Now as opposed to the usual drive testersthis specifically tests the surface of (usually) a spinner.

It will test the surface of the spinningdisk, and I suspect some idea of the performance of the read / write heads.

Download this http://www.partitionwizard.com/free-partition-manager.html my pic will give you the instruction on what to do. It doestake some time but it does cover most possibilities with a drive in conjunctionwith the other testers like Seatools http://www.seagate.com/au/en/support/downloads/item/seatools-win-master/

What do the Capacitors on the Motherboard look like? See any that are bulged or leaking?

Will the mobo will fail only if the capacitor is bulged or leaked?

TVeblen · May 31, 2014

No. There can be other points of failure, but bad capacitors is one of the more common ones.

What comes in my mind is the mobo may be gone faulty as it is 3 years old.

We cannot tell about it finitely in a remote assistance.

But we can say that we have minimized all the other possibilities. Well, only one thing remains there .... the main source of power from the plug point.

You asked about WD data lifeguard ... you may run the quick test and the extended test.

And, the sudden power outage is called abnormal shutdown.

So, the conclusion is, there is a high probability that your guess with right. The troubleshooting process also indicates to it. But we cannot say it with certainty in a remote assistance, unfortunately.

I checked my capacitor, i have just normal rounded capacitor which do not have any line in between, so when I see it looks pretty flat not bulged.

pushkar1989 · May 31, 2014

I will check this asap. Thanks.

It's right where ICit2lol said it was. Your volts appear to be fine.

pushkar1989 · May 31, 2014

Okay, so my PSU is good.
I tested that HDD Surface test but I am getting black screen in between, first I got after 4-5 lines.. And second time I got after 2 lines.

Britton30 · May 31, 2014

You will have 15 or more caps on the board, can you view all of them? Use a flashlight if needed. A bad board is about the only thing left unless it's a bad GPU card, monitor, or cable.

TVeblen · May 31, 2014

If we look at post #1 we can see that pushkar mentioned some corrosion/residue on the pins on the processor. He mentioned that this could be wiped clean (one pin at a time).
Normal chemical reaction corrosion will form a lumpy coating on metal parts. A sticky residue makes me wonder if it could be a case of excessive thermal compound that got into the socket?

The fact that the black screen occurs under any type of processor load points to a bad CPU (or motherboard-socket). My problem with that is that a CPU error will normally end with a shutdown or restart, not just the loss of video. There seems to be a missing piece to this puzzle.

Just thinking out loud.....

I think I missed that in post #1 and I should have caught it. Excessive thermal compound on the processor would account for many issues for it would most likely be in the socket as well. If somehow the pins and socket being effected were related to video processing (think i-series intel) it could explain a lot. I will have to take a closer look at the Amd X6 Phenom II 1090BE architecture to know if that is even possible.
:shock:

Okay, pls check and let me know.

Yes - video on chip
Specs here:
AMD Processors for Desktops: AMD Phenom?, AMD Athlon? FX, AMD Athlon? X2 Dual-Core, AMD Athlon?, and AMD Sempron? Processor
AMD Phenom II X6 1090T Black Edition - HDT90ZFBK6DGR / HDT90ZFBGRBOX

Thank you Sir for that. I was out at the American Legion for Officer Installation and just got back.

I wonder if alcohol and a pipe cleaner would be gentle enough to pull all of the paste off the processor pins? I know the socket can be cleaned with alcohol and a extra soft toothbrush and a can of air.

Britton30 · Jun 1, 2014

Not a pipe cleaner, they have a metal core, a normal cotton swab is best.

The Phenom X6 has no embedded video but may be one on the board. AMD chips with video are APUs and use the FMx series sockets.

Sorry bout that Britton. The Pipe Cleaners I get from my local smoke shop have plastic cores and long softer bristles so as not to scratch the seasoning out of a pipe and I forgot that many places are still selling and using the metal core ones. I don't like using cotton swabs as they tend to leave strands behind. Maybe soaking a toothpick in alcohol would work. Especially if the end is squashed/chewed (before dipping in alcohol of course).

I looked at the specs and I did not see vid onboard but it does state it support 3dnow so in might still be debris on the chip pins and socket. At this point I think everything else has been mentioned / tested.

Britton30 · Jun 1, 2014

His board should have an onboard ATI Radeon HD 4250 graphics chip.
ASUS M4A88T-M AM3 AMD 880G HDMI Micro ATX AMD Motherboard - Newegg.com

I haven't used pipe cleaners for a few decades, didn't know they were plastic now.

I also would suspect bent pins, it takes a very miniscule bend to trash a CPU, been there, done that.

Thanks for the correction Gary. I looked again and can't see what I was looking at to reach that conclusion. My feet, obviously.

ICIT2LOL · Jun 1, 2014

My 2cents again I use a piece of old but straight credit card (about the length of the line of pins) to line up the pins and if possible like my slot cleaning have a piece of lint free cloth over the edge of it and VERY GENTLY move the piece of card along the direction of the pins to straighten them and clean at the same time.

Now as we know the pins are usually gold plated and as far as I am aware gold doesn't tarnish or get corroded the only substance I know that will attack gold is a solution of nitric and hydrochloric acid - Aqua Regia Aqua regia - Wikipedia, the free encyclopedia
I would suggest the "coating" on the pins is old compound that has baked on hard and my other thought is has some compound somehow got into the pin holes in the socket - now that would be a real nut breaker eh?

As Gary pointed outtoo there are a lot of caps all over the board and some are under the cooler of the CPU and can be very small - have they been checked.

I thought too the 5v rail was a tad low but not enough to trigger the Power_Good pin on the 24 pin socket but may be causing a problem somewhere else.
