Probelm with new assembled PC

It sounds like you are out of your depth.

First thing is to identify the motherboard, download the manual from the manufacturers web site and read it.

The CPU runs the POST code out of the motherboard BIOS ROM. When the POST runs it usually 'checks' the RAM by default. If the POST doesn't run changing the RAM won't make any difference.

Have you installed the CPU correctly in its socket? Have you locked the clamp lever on the socket into its correct position?

Have you set the motherboard jumpers and/or configured the CMOS correctly for the CPU?

The quickest way would be to get someone to look at it who has a bit more experience.

HTH

If you read your manual for the MB, you will find there is a BIOS jumper that has to be moved. Did you do that? Regards Lee

It should be the wires connected to power button make sure all those little wires that they are plugged into the right place.........:-)

Check the power supply, do you need 110v and it is set for 220v?

Along those lines, does the motherboard require a special power connection for the CPU? Most do, and the ATX specification has changed many times to accomodate various connections.

Take a flashlight (and maybe a magnifying glass) and look real closely at how your RAM, CPU, and other cards sit. Make sure the fit is even all the way, not higher on one side. (I've added RAM or cards many times and still have to check to make sure.)

You may still need to take the system down to bare bones to make sure something else is not at fault. (CPU, Video card, RAM)

Oh yeah, one more thing. I have one system that refuses to start and work properly after hardware changes until I unplug it and plug it back in.

Most of the time when I get no video. I have found it to be either improperly seated memory or perhaps bad memory.

Check your Memory

First thing to check is that the M/B isn't shorting on chassis or standoffs.

check to make sure you have plugged in the CPU power cable. most of them these days have a small receptical on the board near the CPU.. its normally not near the other master MB power connections.

Make sure head sink with compound is squarely on processor. If you have an air pocket between processor and sink, processor will stop and/or burn up.

Heat sink?

Is this the HCF instruction (Halt and Catch Fire)?

It is not a heat sink problem if the computer will not start up at all.

Unless a heat sink problem caused the CPU to overheat and become toast.

Start with the basics only in the system - Graphics, CPU, memory. dont connect anything else (such as hard disks, cd roms, extra cards etc.) Check there are no additional connectors on the motherboard for power - a lot of them nowdays have extra 4 pin connector on the board for cpu power and will not boot without this. If you get nothing at this stage, remove all the RAM, it should start beeping (assuming you have a speaker connected). if it doesnt then the motherboard may be faulty. If you do get something appear on screen, switch off, add one more piece of equipment (such as hard disk) and repeat.

Not before POST. This is something more basic.

But didn't he say it *never* started up?

Always a possibility.

Yup. In addition, the simplest configuration gives you the fewest sources of problems.
