Can you confirm that you're not getting any beeps from the system at startup? If no beeps, one possibility is that there's something conductive under the motherboard, like a spare mounting post or spacer (the little points of solder on the underside of the board are conductive, and anything touching them can create electrical problems). But perhaps first check that everything's seated correctly. Have you done any upgrades in the past? It can be hard to know how hard to push things together until you get a bit of experience.

You may find it's your RAM which gives you the problem, try getting one which is non ecc reg.

What you got now is normally for server boards.

Most common problem is the wires to case/mobo. Check and duouble check them

Not so obvious and often overlooked:
All the fans and nothing else = CMSO battery dead or not seated properly.
(Don't assume it's good 'cos it's new) ;-)

Duhh - make that CMOS.

Hi all,I have removed the motherboard and made sure the internal battery is ok and well fitted also i have checked to make sure that when the m/board is refitted it is not shorting out also i have checked and triple checked all connections .I removed the 4gig ram and tried a restart I got lots of long beeps from pc speaker.this indicates a memeory fault obvious because i had removed it .I replaced ram and restarted pc again just as before cpu fan and case fan work no beeps from pc speaker no display of any kind on monitor.Retep 888 sugests my ram may be at fault not wanting to tread on any toes or sound ungreatfull but could this be my problem?

you ram may be faulty goto memtest and make a floppy or cd place in the computer and reboot to test memory.

is the graphics correctly seated in the socket plus check monitor lead, do you have access to a space graphics card to eliminate your one.

psu ? can you put it in another pc to see if it works.

worse scenario you may have blown the pc with static.

space should read spare
