Question QDI Advance 6E Motherboard

[pusb32]

Hello,

I am trying to power up this old motherboard. My PSU has a 20 pin ATX connector and a 4 pin connector.

I have connected the 20 pin connector to the motherboard, but there is no connector for the 4 pin on the 'board.

Subsequently I cannot get the motherboard to power up.

What am I doing wrong?

20pin is enough , 4 pin is extra power (if needed)
front panel connection (powr switch) is connected?

Thank you. My power switch cable was indeed the wrong way around

Now having further problems. I cannot get the motherboard/system to boot past the bios screen.

The motherboard powers up and I get a display, it shows details of the cpu, and then does the memory test. Sometimes the memory test shows the correct ram amount, other times it doesn’t show all the ram. Either way, once it stops counting the ram the boot sequence just stops.

I cannot get into the bios setup, pressing the relevant key does not bring it up.

I’ve tried it in the computer case, and out of the case on a cardboard box (in case the motherboard was shorting somewhere), I’ve disconnected all the drives as I thought they could be causing an issue. I’ve removed each of my ram sticks one at a time to check they weren’t the problem, and I’ve removed the cpu to check there wasn’t any bent pins.

I don’t what else I can check. Any ideas anyone?

try reset CMOS battery

Tried that and the bios reset thing with the jumpers, still the same

what is your CPU?

Additionally, do you have two sticks of RAM in there? If so, you might try with only one stick. If it doesn't work, remove it and try with just the other stick. That might narrow down if it's specifically a RAM issue.

Am I correct in assuming you have a heatsink and fan on the CPU, along with thermal paste (don't laugh, it's happened!)

I have tried that with the ram, made now difference.

Yes the CPU cooler is fitted

Its a Pentium III 866Mhz

can u try reduce fsb to 100MHZ?
between RAM and power supply 20pin slots u should be able to see 2 blue jumpers in JFSB1 and JFSB2
righ next to it are pins called JCLK1 & JCLK2

remove blue jumpers from boh JFSB
place one jumper to JCLK1 1-2 pins
place 2nd jumper to JCLK2 2-3 pins

 

[pusb32]

Just tried that, and its certainly done something.

The motherboard now detects the HDD, and then comes up with the message "CMOS checksum error - Defaults loaded"

 

[kerberos_20]

sounds ok to me
btw your CPU will be running now at ~650MHz
your RAM appears to be 100MHz

for normal 866MHz u will need to get 133MHz ram

max ram for your chipset is 512MB per module
