Why reseating the graphics card surrounded by the PC will simply solve the "no signal" problem on my monitor?
1. "no signal" displayed on monitor on cold boot (cannot even see BIOS). But i could see my PC lighting green and running normally (optical mouse lights up and the ivories num lock green after a while; just similar to a normal boot but w/o display on monitor) Then i own to push the power button on my PC to force it to turn off and on repeatedly several times before the monitor detects signal (monitor power indicator turns from ginger to green finally...) However rebooting onwards has no problems. Only on cold boot.
2. Screen will blink (random times but vastly rare, the eyeshade will turn black and after 2 sec reappear)
3. Sometimes screen a short time ago freeze and mouse cursor cannot move. Not even ctrl+alt+del. Had to force reboot by pushing the Power button on PC.
Luckily my friend advised me reseat the video card and it WORKS!
i suspect it might be a video card turning bleak... it is 5 years old. But could it also be motherboard?
Not monitor clearly. New. Only used 1 year.
Any help? Ty
Answer:
Hello,
If the issue never occur again, well in that you go. However if you attain a no signal problem again a video card would be a lot cheaper than a motherboard, could you borrow a video card if this occur again. No signal problem on another video card would lead to the motherboard. Before varying motherboards try re seating the memory first and clear sure there is no dust silt on the processor fan or power supply.
Hopefully the no signal issue is already resolved.
The video card person reseated can help because the connectors on the video card may be worn. This will result in it to provide a poor signal and it takes a while back you catch that signal previously it fizzles.
1. you don't have adequate ram, should hold at least 256/512 if using xp
2. your motherboards cap are going bad, do you achieve funny smells if pc departed on for a while and smell when you come back?
3. you don't satisfactory power to power your pc, what is your psu size?
4. check your system have good cooling especially surrounded by summer as the graphics and cpu will get hotter and inflict the symptoms you discripe
Never argue with nouns.
I assume when you reseated it you also disconnected and reconnected the monitor cable from the card. So you reseated the card and the cable.
If the video card or motherboard was going impossible I doubt reseating the video card would have done anything.
Only replace the video card if you involve to improve presentation. There has be major improvements within video card performance over the final five years.
During operation of the computer the boards heat up. When turned rotten they cool down causeing them to flex back and forth. this cause the boards to become loose and also a slight electrical "glazing" on the contacts. Reseating the board will correct this for quite some time usually.
