I have a desktop computer that I built around 4 years ago. I was trying to get it running recently and am stumped on the issues it is having.


I don't have the exact spec list anymore and newegg doens't seem to record my history that back far, but from what I remember/can see:


1) intel motherboard

2) E6600 processor

3) 4 ram slots , with 2x4GB ram*

4) no built in display (vga, hdmi, ...)

5) corsair power supply


Now the issue is that I do not see any display on boot. At first the computer would boot and make 3 beeps. So I googled the 3 beeps for intel boards and it said it could be the RAM. I then took all the RAM out and put one in at a time. One stick caused beeps, but the other three do not.


Even with one of the other three in though, it still boots to no display.


The monitor I am using works with other systems so that I know it is not that. I also tried several VGA cables (including ones that work on other systems). I also have tried 3 different video cards all in different PCI-E slots, but still cannot get a display. 


Does anyone else have ideas as to what it may be? Is it very hard to debug the issue when I cannot even see a BIOS menu...

Did you try the single stick of RAM in all slots? Try powercycling the computer. Remove and power and hold the power button down for 30 seconds. Then attach the power and reboot. Also try a new CMOS battery. A new battery may or may not work.


It's not perfect but if you have a multimeter, check the PSU as shown in this video. Also make sure all connections from the PSU to the MB are good.
