HELP!!! - New Parts = No POST!

Thimk · Apr 27, 2008, 09:14 PM

I got some new-old parts from eBay to resurrect a machine for the sole purpose of Counter-Strike 1.6/Source. After assembly, I went for my first boot and all I got were two solid LEDs: the PW and HD.

Otherwise, no VGA output, no beep, nothing!

Devices are as follows:

ASRock 939 Dual Sata2 (AGP 8X & PCI-E)
AMD X2 3600+
ATI Radeon HD2600 XT (requires an extra power connector)
300W PSU
1GB DDR400
60GB HD
DVD Drive

Before the switch, all my parts were in perfect working condition.

At first, I thought that I had to do some jumper configuration to specify an AGP device as a primary VGA, but I later found out that was to be done later in the BIOS.

I now speculate that this may be a PSU related issue--I do not have a 4-slot/square/hole connector from my PSU to the MOBO and I don't think that some devices are getting powered. Can anyone confirm this? Similar problems out there?

so you didnt plug in the P4 power connector? thats necessary to power the machine......

Molex to 4-Pin P4 12V Cable - Sleeved [ATX12V] : Performance-PCs.com, ... sleeve it and they will come

Something of that nature (Molex to 4pin P4 12v) will fix your problem. If after you get that and you get the same problem, further troubleshooting will need to be done.

Thing is, the board being replaced (Abit NF7-S 2.0) has a 4-pin connector, and it works fine without power.

higher power CPUs need that to run, as well as certain board components i believe.....

For me it looks like you would need new PSU from 450W-500W range. And it must be sertified ATX12V 2.0 standard.

did you also get a 6 pin PCI-E adapter for the card? because that will not run PERIOD without it.....

Yep, the card was supplied with one.

So this is a common occurance? No 4-pin = No beep & no post?

yeah some WILL NOT WORK at all without it. Very rarely you will see a board proc combo that will but thats usually low end stuff.....and thats still a maybe

I will be getting a new case + PSU this weekend so I'll update this thread then.
