One of the computer in my office has a display problem where the screen will go blank from time to time with the CPU running.
At first I suspected a loose display card, and reseated the card, and it worked fine initially but the problem reoccurred at lower frequency.
Since I don't have a spare good display card, I put the suspected graphic card onto another computer and use it with the same monitor. Now it works just fine.
So, it means the display card, the monitor and the VGA cable are all in good condition, so does this means the motherboard is at fault?
Thanks.

What if you try another monitor on the computer having problems? Does the same thing happen?
When the screen goes blank, what do you do to 'revive' it?
-
What operating sytem are your using?
-
Hi Carbon Dudeoxide, I did not try that because all other monitors are in use. But should it leads to the same conclusion? Because the monitor and display card are working fine with the other CPU.
JJ 3000, it's Win XP SP2.

check BIOS battery and viedo card

I don't have a spare battery to test at the moment.
How do I actually check the video card?
I put it on another CPU and it works fine.

That should be enough for now.
As for hooking up another monitor, it can rule out the possibility there is a fault with either the Operating System or another component in the Computer.

So, if another monitor works fine, then it's the OS.
If another monitor has a same problem, then it's another hardware (motherboard?) problem?
-
If the new monitor works, there is a problem with the other monitor.
If the new monitor DOESN'T work, it's a problem with the hardware or software (OS)
-
If the new monitor works, there is a problem with the other monitor.
To verify whether the monitor is at fault or not, it's currently used on another CPU together with the display card.
And both of them are working fine so far.
So definitely neither the monitor nor the display card is faulty, right?

Can't really tell unless we try another monitor :D
Can you not just borrow one for 2 minutes?

Yea...I know it's hard to judge without trying every possibility.
Well, it's office hour now, everyone is rushing their job.
If I want to "touch" their monitor for 2 minutes, they will kill me...haha....
Anyway, I'll bring home the whole system to test at home. At least I have all the parts to test with.

All right then. ;)

Hi! I'm back.
So, let's assume System A is the one with the display issue and System B is the test unit.
1. CPU A + Display Card A + Monitor A ---> No Display
2. CPU B + Display Card B + Monitor B ---> OK
3. CPU A + Display Card A + Monitor B ---> No Display
4. CPU B + Display Card B + Monitor A ---> OK
5. CPU B + Display Card A + Monitor B ---> OK
6. CPU B + Display Card A + Monitor A ---> OK
So, what can we conclude from that?
-
With that table-like thing, it seems that whenever you have CPU A, the monitor doesn't work. Everything else seems to be fine.
Did you actually switch out the processors?
-
I didn't really switch out the processor.
When I say CPU I mean the board with the other peripherals (except the display card) i.e. everything in the casing.
-
Then it looks like the Motherboard might need replacing.
-
Yea...that was my first guess in my initial post.
Thanks.
