What does 3 beeps mean?

The beep codes are dependent on the BIOS in the motherboard.
MSI uses both AMI and AWARD BIOS, each of which has different beep codes.
From MSI's web site:
Verify POST beep codes
Continues beeps or 1long 2short beeps = possible memory error
• Try re-seating memory or test with different memory
1long 2short or 8short beeps = possible video card problem
• Try re-seating video card, test system with known good video card
High/Low tone (siren sound)= CPU is overheating.
• Verify that CPU heatsink is properly installed and power connected
AMI Beep Code
Deep Code Description
1 short DRAMS refresh failure
2 short Parity circuit failure
3 short Base 64k RAM failure
4 short System timer failure
5 short Process failure
6 short Keyboard controller Gate A20 error
7 short Virtual mode exception error
8 short Display memory Read/Write test failure
9 short ROM BIOS checksum failure
10 short CMOS shutdown Read/Write error
11 short Cache Memory error
1 long, 3 short Conventional/Extended memory failure
1 long, 8 short Display/Retrace test failed
AWARD Beep Code
Deep Code Description
1 Long, 2 Short A video error has occurred and the BIOS cannot intialize the video screen to display any additional information
Any other beep(s) RAM problem

That CaptStumpy is backing up? ???
But seriously, I assume you mean that the unit will not POST at all and the display does not come up. There are really only four probable causes for beeping with no display:
1. RAM problem. Either bad or flakey chips, not seated securely in the socket, or just the wrong flavor for that mainboard if you're upgraded/replaced/swapped them recently.
2. Video card problem. Bad card or not seated securely in the slot. If you moved the PC recently it may have been jarred loose.
3. CPU problem. Unlikely, unless you overclocked it or fiddled with the CPU fan recently, but it's a possibility. If it's a P-II or P-III it may be in a big wide slot and could have been jarred loose like the video card. Check to see if it's fan is running.
4. Motherboard failure. Time to upgrade. This is actually more likely than a CPU failure, but less so than the RAM or Video card.
Darth Sidious:
There should be a 'Most Useful Information You Never Want to Have to Use' sticky for things like this.
Great info!
E_Look:
As the thread starter, I hereby officially request a sticky for this thread in the next post, I'll say why.
