Now I could be wrong or am reading this wrong but if the card is plugged into the board the HD onboard graphics will be cut out.
To use the Intel graphics I found to manipulate it I had to do this (for an example)

HINTS ON ADJUSTING INTEL GRAPHICS ON LAPTOPS

If you areusing or can only use the Intel graphics in your laptop machine (some laptopsnow have dual graphics chips ie Intel for general use and NVidia for heavy use– gaming etc) and want to use two monitors – for example a larger one with alaptop, and the “secondary” monitor ie the larger one the screen needs scalingthat is to get the screen within the monitor’s screen (bezel) edges – read on.

NB if you are changing the aspectfor the larger “secondary’ monitor you must first do this.

Start>Control Panel>“Display”> “MultipleDisplays”> click “Show desktop onlyon 2” (this will cut out the primary machine screen while you are adjusting thelarger monitor and not change the machine’s own screen aspect ration

IFit gives you an option for a different resolution – for example the larger monitoris 1920x1080 then change that however if the laptop for example only supports1600x900 then it might not be capable of doing that.



This worksreally well with recently manufactured Intel graphic chips and those machinesthat have the update from this link https://downloadcenter.intel.com/ this link gives one the best available graphics from Intel atthis time.

Now you haveto pick out the driver after checking this link out and for example my link formy Asus ROG gaming laptop was https://downloadcenter.intel.com/search?keyword=4th+Generation+Intel%c2%ae+Core%e2%84%a2+Processors+with+Intel%c2%ae+HD+Graphics+4600

STEP 1.

On the plaindesktop right click and it will give you a window with some options.

STEP 2.

Click onGraphicsProperties” - that will open the “Intel graphics control panel”as per pic (takes few seconds).

STEP 3.

Click on “Display”– and select ‘Customise Aspect Ratio” - there will be two sliders onefor horizontal and one for vertical.

Click holdon each one and slide them in their respective directions until you see the edgeof the screen come in from the edge of the monitor bezel and them just slidethem back to where they are sitting exactly where you want them.

Then - click “Apply” and then it will askyou if you want to keep this configuration – click “OK”– it is done!!

You also get the option to save the settings in a dedicated file- I just named mine ASPECT BENQ -for this particular monitor. This so if I use another brand monitor and havechange back to the Benq for any reason I can hit that file and the settingsshould be applied – I have not needed to do this but it makes sense that iswhat will happen.



You can still use both monitors if desired by altering the Control Panel > Display (as above procedure) and setting it to use both screens –the laptop screen will not have changed from it’s default settings.

See pics.

This is just an example I used for the scaling problem I had at the time but it may help you use the Intel HD a little better.

For any faulty caps they can be located looking for bulging at the end and / or scorch marks where they are attached to the board or they can even be split and oozing the material form within. Pus I think you may know already there are more than one type of capacitor too see pics - and there some that are green in colour but are usually used in low voltage apps.

I don't see any budged caps on motherboard or graphics card. However, I found something strange with 4 capacitors of 820µF on graphics card. Using a digital multimeter, I found these capacitors are shorted. However, the same 2 capacitors are not shorted. I don't have a tool to check ESR value. But capacitor shouldn't be shorted right? If not,what is the point of placing capacitors there?

That is a good read from Layback mate and if you mean shorted then no caps should show zero volts unless they have been left for a very long time. In addition to Laybacks link there is this too How to Test a Capacitor however it is very simple and the types I mentioned you can see then at the top of this article so you can see not all caps are electrolytic although they are the ones that usually cause us problems https://en.wikipedia.org/wiki/Capacitor

In my experience they are one of the most common causes of failure in electrical circuits and it only takes one to take down the system.

I will definitely take a look at that. However, I found another interesting case - that's the card is not fully dead. What I did was,
Removed the card-> booted the system using integrated graphics->went to the bios->Enabled Integrated graphics "Always" and set Primary graphics adapter as Integrated graphics. After that, I plugged the graphics card and connected monitor via integrated graphics. The system booted normally and the graphics card indeed was detected. So, I believe something is wrong in between the GPU and ports. If GPU/memory was the one causing the issue, then drivers were never installed properly.

UPDATE : I checked capacitors while operation. The capacitors rated at 2.5V were showing 1V and some of them were at 0V. those rated at 16V were showing 12-13 V.

Yes mate the caps are rated only for a max working voltage it doesn't mean they have to be that voltage as they build in a safety measure of voltage when they make caps . IE stick a 100v cap in a 250 v line and soon the cap will go south as that safety measure of voltage will be exceeded.

Also you will find that electrolytic caps (ones marked pos and negative) connected the wrong way round will explode and the bigger the cap the nastier the effect and can shower one with some very irritating material not to mention the mess. take it from one who knows.

PS Meant to mention too that reseating the cards probably did some good too and if you do it again try this

GENERAL SLOT CLEANING

Now as for anymotherboard slots to clean them use a strip of old credit card (or any cardthin enough some are better than others ) about 1/2 inch wide nip the cornersoff one end - preferably round themoffhold a piece of thinlint free cloth over the end dab on some form of alcohol - isopropyl alcohol(what we swab the skin with before an injection) is good and GENTLY swipe along the slots.

This can also be done for the GPU slot/s andalso the contacts of the sticks or other cards - not the stick but some lintfree cloth of course. See my pic for the stick but please be very gentle doingit if you are in any doubt - please ask before doing it but I use this all thetime and have yet to damage anything

Tried that. Still no luck. I think the card is a broken one. Like others, I am going to use it as a Sapphire HD7750 1GB GDDR5 paperweight.

hmm the cookie crumbles like that sometimes mate the one you have listed in the specs looks like it might make a good replacement.

Thanks a lot for your valuable suggestions. Yes, that's an ASUS GTX 750 Ti OC 2GB GDDR5. I upgraded to that since this HD 7750 has issue.

1. If the computer runs properly for months after installing the new power supply, the power supply did solve a problem or this wouldn't of happened. If another problem happens months later then it's exactly that; a new problem.

2. Hooking a DOVM to a powered motherboard will probable cause more problems.
Capacitors are measured with power off and the capacitors discharged.

**Please read the tutorials posted and Google for more if needed**

3. Measuring various points on a motherboard other than basic voltages and grounds at the hardware connector pins is not going to give you any useful information.

4. With a lot of special training, schematics with needed information and a oscilloscope you are going to do nothing but more damage to the motherboard poking around on it.

5. Their are reasons we don't do more tests other than visual and basic voltages and grounds.
The reason is we would need a lab with all the proper equipment and information to test motherboards.
Motherboard manufactures have such equipment, information and training. A basic oscilloscope would cost more than a motherboard many time over. Even if one had a oscilloscope and hooked it up wrong you will destroy a powered motherboard. I haven't done this type of work in about 30 years but I still remember a lot of do's and don't. It would take years of training and schooling to understand the complexity of motherboards.
