PC-Monitor Connection Issue: Replaced Motherboard & Graphics Card, No Signal Detected

Question

Hello

I have a problem with the connection of the PC and the monitor, namely when I start the computer, the monitor does not get a signal. Everything seems to be moving and the monitor is not. I replaced the motherboard and graphics card and then the same. What could be wrong?

greetings

Maybe a stupid question and you replaced the signal cable?

c4 · Answer

When I connect the monitor to my laptop with the same cable, everything works fine

iron64 · Answer

Describe the equipment, i.e. the names, symbols of the elements, did you measure the voltage of the power supply and does the speaker squeal?

szymsze87 · Answer

Not even the splash screen and POST visible?

c4 · Answer

The screen has a green LED, but the screen is black and white. Probably MSI MS6340 disc, GeForce 2 card, some NEC monitor. I have not tested the voltages and the loudspeaker is silent

If the loudspeaker does not speak, it is quite a bad sign, maybe something about the power supply? greetings !

Have you tried to connect another monitor to this PC?

pecet7 · Answer

I bet on graphics.

I have already met several times with monitors that did not respond to every PC, sometimes it was a small broken wire in the control cable and more than once with cold soldering, there are also monitors that have permanently attached control cables and a worn plug can work wonders no color or a pink screen or the monitor is unresponsive

if nothing is squeaking with the announcer, it can be bad ... see if the card has not come out of the slot and see if all the fans are spinning

It may sound silly, but once I had a similar situation and it turned out that everything went back to normal when I unplugged one of the drives, which later turned out to be faulty and blocked the BIOS. My advice: try disconnecting the drives or the floppy disk drive. If the problem disappears, the fault lies in the broken device that you removed.
Greetings.

You could even try to start the PC without any drive, at most it will squeal that there are no ons1417 drives may be quite right, the damaged drive blocks the power supply and the prock does not have all the voltages then

Hello, I have a similar problem as the author of this thread.
So yes - the computer worked without any major problems for 1.5 years, but a few days ago during the game there was no signal for a while, it reset and it worked ok. A day later there was no signal for the monitor. I checked another monitor, a new cable, and then the same problem. When activating the internal loudspeakers it makes two long beeps followed by 8 short beeps. I really have no idea what could go wrong and would be very grateful for your help. I would like to emphasize once again that the computer ran for 1.5 years, approx.
greetings

Check your BIOS - AWARD or AMI - and decode the sounds using the website -> bioscentral.com (Bios Beep Codes).

sksik · Answer

A więc: posiadam bios AMI i według tej stronki:
8 short Display memory read/write error The system video adapter is missing or defective

i druga możliwa opcja:
1 long, 8 short Display test failure The video adapter is either missing or defective

mat_ed · Answer

Clean the computer inside, especially the AGP slot. Clean the graphics card contacts.

nutergsm · Answer

Probably I had the exchange card the same, sometimes it turned on until then only such squeals as you 2 long and 8 short ones were helped by replacing the card.

TheGreK · Answer

Try a different video card and see if it works ... Maybe the agp port clicked.

sksik · Answer

I cleaned it did not help, I have no place to get another graphics card, I will have to buy a new one, but if I buy a new one and it is not the fault of the card but the port, nothing will happen to the new card? If it's the port's fault, is it going to be checked somehow?

TheGreK · Answer

It doesn't necessarily have to be an agp port. Borrow from a friend and check. Do not buy anything until you find out the cause of the fault.

sksik · Answer

Well, this is where the problem is, I have no one to take from, everyone who knows it works on a laptop.

nutergsm · Answer

Ideally, go to the computer shop and let them check if you buy the card right away.
