Post by: booty on March 21, 2007, 02:41:56 AM

Hi all ive just bought a new motherboard, cpu, and video card which are:

ecs rs400a lga775 atx motherboard

A bit more info...
Any beeps at all ? ?
Did you use thermal paste when assembling the CPU ? ?
Is this a new PSU or your old one ? ?
Did you remember the 4 pin power connector to the MBoard ? ?

MBoard shorting on the case...
CPU fan not installed properly...
Inadequate or failing PSU...
RAM not seated properly...
ETC. ETC.

It can be quite a few things as you can see.
Try it with just the bare minimum: 1 stick of RAM, video card, CPU, fan, mouse keyboard and monitor.

Then add one item at a time until you find the culprit.
