You right click on the bottom taskbar and select Task Manager. In Windows Task Manager, you go to the Processes tab. Dead simples.

Then you left click the word CPU (twice) so that the highest...

I'll take your word for it on RAM and knock that off the suspect list.

Your processes list came out rather un-columned if you know what I mean. But it showed NO CPU usage. What is using CPU at...

LOL!

Aaagh. 256Kbps. I'm amazed that you ever got to even 30fps on CS. You must live miles from anywhere.

Anyway, you said that your fps is poor when you play offline. That's important information. ...

It's a shame you have to buy a card. My diagnosis may not even be correct, though it's logical. I recommend, if you do buy, the cheapest NVIDIA card you can find with 256MB RAM. They're not...

Well, you're there right in front of your PC and we're here, perhaps thousands of miles away. The usual forum diagnostic problem.

So, on the basis of your words, the next place to look is your...

Great. Then you'll be marking this thread as SOLVED!

I'm assuming that power actually goes off and this is not an error code blinking on the power LED. On that assumption, logically it should be one of three potential causes:

1. The power section...

We'd prolly need to see what else is runnig. A list from Task Manager/Processes would be helpful (sorted by CPU usage).

e.g. new anti-virus version now using more CPU.

In my opinion, if the machine boots (you see disk activity as per normal boot) but the screen stays blank at all times then there is usually something wrong in the output side of the video card, or...

Load Windows in Safe Mode (Press F8 during boot) and it will display in VGA. Then you can deal with the driver and boot again normally.

Perhaps you could do this search in Google: "led screen circuit diagram"' there appears to be something to get your teeth into.

You can google this and you'll find a lot of it around.

Usual reason is a capacitor or a piezo component has failed in the monitor. I've got one of those and it eventually comes on after about an...

Onboard graphics should work when you remove a graphics card. Maybe there is a BIOS setting you can change with the graphics card in, to enable onboard VGA.

In any case if your onboard VGA was...

If you compare your post #4 with your post #1 you can see why I asked my questions. Was it the laptop LCD or the "vga monitor" (hence my describing it as CRT) with its vertical bars.

Anyway, your...

Your information isn't quite enough to enable a reasonable diagnosis at distance. First gut reaction to the LCD remaining dark is that the system still thinks it should be booting and displaying on...

Lid switch problem?

The causes on a CRT are likely to be any of the following:

- VGA cable problem or pin bent on connector or not fully puished in.
- Decayed component for the complementary colour.
- Video card is...

Is the cable properly seated? Is this a DVI or VGA connected monitor?

If VGA (as I suspect) and if your monitor graphics card support DVI, how does it behave with DVI used?

Does another...

Have a read of the attachment. It explains what happens when.

I know you're asking about why it's changed since 3 months ago but it gives us both time to think about it once more.

The thing to...

Does it matter except for the sake of knowledge?

Anyway - during POST the CPU uses your Video card BIOS at VGA resolution. During Windows boot, the basic Windows VGA drivers are used unless you...

Do you have a question?

Please start your own thread and provide full details of what is happening.

I realise that English is not your first language but what you have asked unfortunately doesn't make sense.

What...

Please mark this thread as SOLVED. By the way, what make/model is your UPS? It's a matter of interest to know which UPS brands have imperfect sinusoidal output.

Good news. Fitting that to my explanation (and I should have thought of that), if the ROM BIOS at POST can't get to the Video BIOS because of a card fault, then voila your symptoms.

Well done.

No it won't damage anything if my diagnosis is correct - i.e. on battery driven UPS only. It means that the sinusoidal interference or drift is causing an electrical resonance that comes out in a...

The buzzing normally changes if you change brightness/contrast. It should reduce buzz if brightness is turned up.

I'll make an informed guess here.

I think it's coincidence - you're running...

Hi Mahela

As you know I've been dealing with your situation on the other thread.

Rik's got it right, of course. I have two viewsonic monitors connected to my HD laptop. Neither monitor...

Well, I tried it this morning.

I put both cables into a Viewsonic 2265 - that's VGA & HDMI. This is what happened:

1/
On boot, the signal definitely came through VGA because I could see the...

You can either wait for me to try it some time this week (when I eventually re-boot)- no harm will result but I can report behaviour and which cable becomes the active one after booting.

Or you...

You're welcome. Do please mark this thread as SOLVED.

Yes - the monitor is adjusting refresh rate from VGA to whatever setting the now available Registry tells the driver.

Nothing wrong; nothing to repair. My main monitor (LCD) does this.

Sounds like that to me. What do others think?

Try it. I can see what you want to achieve.

I could try it but (sorry) can't be bothered. No harm will result. My guess is that the VGA port will be acquired first and will be retained.

Let...

There is a straightforward reason. When you boot, default VGA video drivers based on the BIOS of your graphics card are used. That is because there is nothing else from Windows loaded at boot up. ...

Logically, I'd say that either the PSU isn't delivering correctly to the MOBO or the MOBO itself or the CPU is stuffed. When you boot, the Boot ROM executes a sequence in the CPU. Fanns have to...

The issue to which I'm referring is the top-slicing of RAM according to Video RAM size and the knock-on effects that result in other areas of PC performance.

http://www.repairfaq.org/sam/monfaq.htm

Read this lot! Should do the business.

Also, remember that 1 GB graphics card will top slice 1GB from your usable RAM. This, in turn, might (probably would) increase paging/swapping with noticeable lag on games that demand a high frame...

Not just probably. Definitely and those problems are not user fixable.

There is an outside chance that there's a ribbon cable kink/issue that can be sorted by a repair shop - but not usually by a...
