Check graphics card… if nothing works, buy a new one.

Total black screen, did the system manage to POST

Advante_101 SG

No leh orionlight...totally black..Just CPU with fans running..

Is there anything i can do like check a specific part to ensure it is fit correctly ?

Maybe i write a short summary of what happen.

-1st problem encounter is same as current situation ( blank screen,beeping sound.unable to log in window)

-Send for repair shop. in a few minutes he solve it. Computer able to log in window.

-Three days after a child slight knock into mine CPU. ( cant log into window,blank screen again )

This time i sent another new repair guy into mine home ..he see see touch touch say i have to change mine power supply.Then ok lo. after changing the power supply he touch wire abit here and there and voila mine computer can log into window again.

This time i was not at home..when i return i saw the kid playing with mine computer. mine com was hanged on mine pc game cilvislization IV with graphic abit distored. ( funny unmatched colour with unmatched vertical and horizontal pixel appearing in dots )

since mine computer hang..i bo pian have to push restart. When restart..mine computer stop at this msg....i cant remember but something like this...Due to a change in software or hardware problem or a sudden stop in ur computer blah blah blah ...There is 3 options

1 is to enter window in ms dos format
2 is to enter window in safe mode
3 is to enter window as usual

i tried option 3 many times..cannot it just keep on restarting and restart and back to this msg again to choose 1 of the 3 options.

i tried option 2 enter into safe mode and choose system restore to a earlier date also didt not solve...

i keep on trying and trying hoping maybe i can solve it until to this state...A totally blank screen with a msg appearing for 1 sec saying No Signal Input..CPU beeping sound is gone..just the normal fans running and such.

Anyone know ?

MyPillowTalks SG

i know it sound stupid, but

Check that the wires inside did not came off
The ram is not out of position
the graphic card is properly sloted in the slot
the VGA cable is fine, no broken pins

No signal means no singal from graphics card.

sounds like graphics card loose or died. Try plug out and reconnect your graphics card.

if cant work then maybe can try changing graphics card... ...

and next time, remember to set a password on the computer so your kid cant access it again. you cant leave your computer open to people without permissions...

How much is a graphic card nowadays?

lpx88 SG

The PCI Express cards are quite cheap..a competent one costs about 100 plus..

1st problem - Looks like your CPU is another one that cannot take knocks. One knock probably loosen the graphics card.

Or your monitor cable is not secured enough.

2nd problem - A forced restart will often corrupt Windows. Please do a repair of Windows. http://www.sgforums.com/?action=thread_display&thread_id=228859

Repair won't make you lose your files, but you most likely have to reinstall your programs again.

orionlight SG

Most likely the graphics card had been trashed by the person playing the game on your game.Umatched colour and shapes=artifacts on your graphics card= graphics card up lorry.

Alternatively, try to reinstall XP and reinstall your graphics drivers again

When you push the restart button, was the hard disk operation light on? If it was writing to your hard disk and you did a reset, you could have damaged the hard disk.

That's why your Windows couldn't boot up. Your system files could have been damaged.

Check that your monitor cables are properly plugged in, with the power off ensure that the graphics card is properly slot in too and is the power supply to the graphics card plugged in.

How old is your graphics card?

If it's under 1 year, it might still be under warranty.

Can try clearing out your BIOS too. There are 2 jumpers you have to short in order to reset the BIOS (you have to look at your motherboard manual to know which are the 2 jumpers).

Yeah, find out the cause first. If you PC is so touchy cannot stand letting a kid touch, then actually should just buy new PC. Laughing

Try to boot from bootable CD, windows or linux, when you encounter this problem and see if you hit the same problems. This will help you determine if your windows got problem. But not likely since you can't even see the POST screen.

Other than checking the cards are seated correctly, maybe also change different power or vga cables (if you have), could be cable rosak.
