Build with no post, round 2. HELP!

[m4dioses]

So.. I made a post last week about a build I was doing, I had ordered a BFG 550 and a Gigabyte EP43-DS3L to compliment a Q6600 and R4850 I had, the system was a build for my younger brother.

This is the thread from last time, the steps I performed in there - I performed again. Again, I can't get -ANYTHING-, no power at all to the system. Now when I I flip the switch on the back of the PSU, the keyboard lock keys will light on for 2 seconds then turn off - this is the only sign of power I get.


My question is, even though I tested the PSU with a Multimeter and I jumped it with a paperclip (which powers it) is there still a possibility it's bad? I've replaced every other part in the computer at this point, but I didn't think the PSU was the culprit because I could jumpstart it and the multimeter showed response. This system has been offline for almost 3 weeks now, which is really disheartening, not only to him but myself as well since I feel it's my responsibility to get it back on-line. Any suggestions or help will be greatly appreciated as this is quite irritating at this point.

Thanks in advance for reading and helping in any way possible.

EDIT: Also, since that last post - I replaced the ram with new A-DATA ram, and when I tried the PSU in my rig this time - it spun the fans then turned off..

Dead Sapphire 4850.. Go go Newegg RMA. Asus R1950PRO on standby.. funny it wouldn't boot without the video card at first, then after jumping the PSU and putting it back in, it booted 4 times without the video card. It also boots now with the R1950PRO in it, every time.


That's two dead products from Newegg in three weeks.. It's also odd how the PSU would NOT power my rig, which is running on a Corsair 520 just fine...

Wondering if the PSU is still faulty, any suggestions? Would be 3/3 on dead parts from Newegg. >_>

Wow, your threads went untouched. sorry. The BFG LS series, from what I've read, is a pretty good PSU. Though, your unit may have something loose or some slight defect, but I'm not sure since it now powers on everytime.

Reading your old thread, I noticed you didn't try the system without a vidcard... which is the next thing I would have recommended. Next would have been trying your vidcard in there, then trying your PSU... so on and so forth.

... My question is, even though I tested the PSU with a Multimeter and I jumped it with a paperclip (which powers it) is there still a possibility it's bad? ...

Yes, small possibility. Its best to test a PSU with something connected to it -- test it with a load. However, there really is no surefire test a typical end user can do.

Sometimes you, Danny or tiraides just aren't around to provide consulation, that's okay


I didn't note it, but I did attempt to boot the other system with the R1950PRO.. never tried to boot the other system without a video card (standard procedure, donno why I didn't try it). I'm still fairly confident the other motherboard I had at the time was DOA, if it wasn't I'm just going to be ignorant and pretend it was after waiting for the new one.

I ran prime95 on vista64 for almost 11 hours, no blue screens, no crashes, etc.

I noticed the ATX connector from the PSU does NOT snuggly or even really securely attach to the EP43-DS3L. After one reboot, the system would not power on and I had to pull the ATX connector, and push it back down - I noticed that when I pulled it off, it slid right off - as easy as loose tennis shoe.


Also, thanks to those (enginurd and I think tiraides) who reccomended partitioning the outter part of the platter of your drive just for the OS, created a 32GB partition just for Vista64 and the windows experience rating went from 4.9 to 5.6.. Also noticed faster boot times and better in-OS response.

Sorry for the rant, just happy the system is finally booting.

In closing, the difference between a R1950PRO and a R4850 is huuuuuuuuuuuuuge lol.
