On boot i get 3 short beeps twice but the pc then starts ok

Did you check your monitor with other system or individually. If it works fine in these conditions then the issue belongs to your pc.
First of all, you have to confirm that is it the problem of VGA itself or the motherboard. For this, you have to see that does system beep when you start it because system with beeps having the error and the beep sound with continuous or 2-3 beeps relate with different issues. I am going to write down the beep conditions.

1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card


best of luck!

Hi

THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error


or this might help

note that AWARD relies on motherboard manufacturers to develop their own beep codes - the above are only their own internal codes. You will need to refer to your own manual for an explanation of precise codes.


Standard IBM beep codes.

No beep - Power supply or motherboard failure

1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

Your beep codes are..
1 short beep System is OK
2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem
1 long, 1 short beep System board problem
1 long, 2 short beeps Display adapter problem (MDA, CGA)
1 long, 3 short beeps Display adapter problem (EGA)
3 long beeps 3270 keyboard card .
So looks like a display problem, have you tried any of the recovery/restore options available when you press F8 on boot up

You really aren't giving much info, so here are some beep - codes, also make sure nothing came loose on the motherboard or other components ( do this ONLY if you know how ) Safety first.

BIOS Beep Sound core list

AWARD BIOS

1 short(Beep) System booting is normally.
2 short(Beep) CMOS setting error
1 long - 1 short(Beep) DRAM ERROR
1 long - 2 short(Beep) Display card or monitor connected error
1 long - 3 short(Beep) Keyboard Error
1 long - 9 short(Beep) ROM Error
Long(Beep) continuous DRAM hasn't inset correctly.
Short(Beep) continuous POWER supply has problem.

AMI BIOS

1 short(Beep) DRAM Flash Error
2 short(Beep) DRAM ECC Check Error
3 short(Beep) DRAM Detect Fail
5 short(Beep) CPU Error
6 short(Beep) Keyboard Error
8 short(Beep) Display card memory Error
9 short(Beep) ROM Error
1 long - 3 short(Beep) DRAM Damage
1 long - 8 short(Beep) Display card or monitor connected error

I went to google and it seems like the beeps can be problems for different problems in the hardware, this is what one message says,  there are lots of computer beeping answers out there: 1 short beep is your BIOS saying "HELLO I'M OK" 

Standard Original IBM POST Error Codes 

1 short beep Normal POST - system is ok 
2 short beeps POST Error - error code shown on screen 
No beep Power supply or system board problem 
Continuous beep Power supply, system board, or keyboard problem 
Repeating short beeps Power supply or system board problem 
1 long, 1 short beep System board problem 
1 long, 2 short beeps Display adapter problem (MDA, CGA) 
1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 
3 long beeps keyboard card 

Each BIOS company has modified these codes over the years.

hi im josh in cebu phils. may i help you? the problem of your IBM pc is ROM errors that gives 3 beeps in series of 3 sets 9beeps in all.
You need to replace you cmos battery on the mother board.12voltd batt. it maybe empty thats why it beeps or go to setup bios.then restore all the defaults in your pc. and the last one no choice reflash or reformat your pc there maybe files that are missing.

Two short beeps = "Parity circuit failure"
This code usually means a problem with either the system memory or the motherboard.
Solution: change the memory if still beeps then motherboard is defect.

The response from ASUS tech support - It's a standard Award BIOS, so they're the standard beep codes.

So I wrote the following on page 3-4 of my user guide:

1 long + 2 short = Video adaptor error
1 long + 3 short = No video card or bad video RAM

high freq beeps while running = Overheated cpu

repeating high/low = cpu problem

repeating (endless loop) = memory error

the vga board has failed, its a very common problem in acer laptops, you can get a replacement part from www.acerparts.com im not sure if they ship into us but for europe thats where I get my parts.
my acers vga failed two times, ones within warranty and 12months after that, I have to say that acer products are really bad quality, I'm not sure about the latest models but from what I've seen the vga chipsets have real issues with the motherboards and keep failing over and over again.

I have not looked inside your model but the vga is either integrated into the motherboard = that means the repair will cost the whole motherboard, better to buy a new one.

if your model has a removeable vga like mine does, then you can consider changeing it to a new one. contact acer parts.
One of the covers in the bottom is the memory, one is network and last one I don't remember.
here are the contact details if your acer is out of warranty
http://www.acerparts.com/contact_us.php

The parts for your model are at http://www.acerparts.com/index.php?cPath=561_562_1064
you will have to contact acer parts directly, it may be that the vga is build into the motherboard or then the vga parts are not listed.


Hope this may help;
