I recently had a wonderful computer built and now it won't boot. Here's the specs. Core 2Duo 2.4, 2GB ram DDR2, 680watt psu 3 fans: 120, & 2X 80,OS:XP, and I have an onboard video card that's always been somwewhat flaky. I've turned up fsb to have cpu @2.9. System passed numerous sdtress tests. I just tried to install 4Gb of ram and the system made a flatline sound. I was told to put the old ram back in then turn down ram spd below default of 800. I can't the system won't boot. Normally during tbooting the system will beep; there's no beep, and no picture. What can I do?

There should be some sort of beeps then. No beeps is an indication the CPU or RAM is not seated properly. You need to refer to board manual if there are beeps. There is also the matter of... Never mind I just noticed the CPU is an 8 core CPU, but the board supports quad core. Board specs http://www.gigabyte.com/products/product-page.aspx?pid=3833#sp
Parity is a memory ( Ram problem ) try removing 1 Stick. or changing it into another slot. if you suspect Bios. remove power cable. locate The CMOS Battery. remove for 10-15 seconds, And replace it. this will reset the bios to it,s default settings. you,ll know if your asked on boot-up to run setup to change time/date.
Well depending on your bios version, it could be an array of things.
First try removing the video card and re-seating it.
Then re-seat the RAM.
If the problem persists re-seat the CPU.
Let us know the exact model of your motherboard so we can better troubleshoot your problem.
When you turn on your computer the system does a POST (Power On Self Test). If the POST sees an eror it will tell the BIOS (Basic Input Output System) and the BIOS will beep a code or display a code that indicated the problem.
Different motherboards contain different BIOS versions. BIOSes use different beep codes for problems depending on the manufacturer.
do any lights come on ... on the motherboard itself... some have lights some don't.
i would suggest it is a hardware failure.... if you have onboard video remove the video card and attempt to boot.... .. unhooking devices will help you to narrow down what the issue is...
also shut off the power and unplug it.... feel the capictors on the motherboard with your fingers... do any feel rounded at the top ?
You should only hear 1 beep. That 1 beep is power on self test, known as P.O.S.T. That loud flat line sound (And I'm pretty sure about this), was you're CPU. Just because you ran & passed the stressed test is nothing compared to running the system under load? That's why when you put in you other memory nothing changed. If you hadn’t mentioned you clocked up the FSB I would have come to the same conclusion hearing the loud flat line statement. Can you test the CPU in another board? That is about the only way to be sure it's not the CPU. Memory does not make that kind of sound. Memory makes short & long beeps. You can try clearing the cmos/bios by going to pg. 2-18 in you're user manual. This will reset the bios back to default settings & cross you're fingers!
If I can be of more service, just post back & let me know how thing go.
