No video output

Rt2002 · September 11, 2019

So I was changing my GPU to my other desktop (Gtx 750Ti) after removing it and putting the VGA cable on motherboard VGA connector when I turn on the PC I have no image, no post, and every 3 seconds the motherboard bips.

I tried other PSU, reconnecting the GPU, all ram slots (one and two sticks), even other CPU a spare i5-4430S that I have.

I really need my PC and it won't just post can you guys help me please?

Thanks

Was the onboard video enabled in the bios before removing the video card?

Otherwise you will need to lookup the post codes for your motherboard to find out what the beeps mean.

AMI BIOS:
1 beep - System boot successfull
*1beep - Refresh failure - (NO VIDEO) memory refresh failure (bad memory)
2 beeps - Parity error - bad memory
3 beeps - Base 64K memory failure - bad memory
4 beeps - Timer not operational - bad motherboard
5 beeps - Processor error - bad processor
6 beeps - 8042 gate A20 failure - bad cpu or mainboard
7 beeps - Processor exception interput error - bad processor
8 beeps - Display memory read/write failure - bad video card or memory
9 beeps - ROM checksum error - bad BIOS
10 beeps - CMOS shutdown register read/write error - bad motherboard
11 beeps - Cache memory bad - bad CPU or motherboard
12 beeps - BIOS rom file incorrect size - The BIOS ROM file found does not match the size of the flash device
13 beeps - BIOS rom image mismatch - The BIOS ROM file layout configuration does not match image present in the flash device
5 short + 1 long beeps - Memory error - No memory detected in the memory slots.
6 short + 1 long beeps - Memory error - EDO memory detected in system
7 short + 1 long beeps - SMBUS error

AWARD BIOS:
1 short - System boot successfull
2 short - CMOS setting error
1 long 1 short - DRAM or M/B error
1 long 2 short - Monitor or display card error
1 long 3 short - Keyboard error
1 long 9 short - BIOS ROM error
*repeated beeps - DRAM error
*repeated short beeps - Power error
*Repeated high & low beeps - Processor is damaged/Overheated
