I'm not sure if this is the right place for this, but here goes:
I recently had to replace my motherboard and so got myself an Asus P5Ql Pro. I have a BFG NVidia 8600 512MB video card, a brand new SATA hard drive as well as a Pentium 4 dual-core 2.4GHz (I think) processor. Here's my issue:
After connecting everything and ensuring everything is in place firmly, I try to boot up and what do I get? Nothing. It doesn't POST (or at least I don't get any beep codes) and all it does is sit there. At least it stays on (better than the old mobo), but that does me no good when I can't do anything with it.
Any ideas? I just rechecked everything to make sure it's all firm. I saw some info online saying it's easy to accidentally damage the mobo beyond useability, but I've been less than careful with these things in the past and they have still worked. I was more careful this time to make sure I did as little damage as possible, but I am not ruling out that possibility (which would suck, because it was a gift and I can't go out and get myself another one at the moment). I was trying to reset the CMOS chip, but I can't seem to get it out and obviously don't want to damage anything. Is there anything else I can do to get this machine back up?
It would be nice to be back up and running on it...it's been almost 2 months without my desktop
I don't think it's a bad board, unless I have terrible luck. I just built a brand new system, using entirely different hardware and I am encountering the same issue - my system won't POST.
It has a quick-boot feature, which I assume it attempts because it stays on for a minute, shuts off, turns itself back on again and then just...sits there. Fans spin, but I don't get any beep codes and the monitor doesn't start up.
I'm kind of at a loss here and I am hoping you guys can help. I've already tried different configurations, including changing the RAM around, unplugging everything except the RAM and CPU, etc. At this point, I have done about everything I have come across to try, so if anyone has other ideas I am very open to hearing them.
One system is an Asus P5QL Pro with 3GB of RAM (2x1GB, 2x512MB) which is all DDR2 667, An ANtec 430W PSU, BFG Nvidia GeForce 8600 512MB video card and an Intel Dual core Processor (2.4GHz)...not a Core 2 Duo.
The newest system is an Asus P5QL motherboard with 2x2GB OCZ DDR2 RAM (I can't remember the speed right now), Intel Core 2 Duo 2.6GHZ CPU, Ultra 650W PSU, Saphire ATI Radeon HD 4670 512MB video card.
I hope that helps narrow things down. I may be wrong about the processor...I'm not at home at the moment, so I can't remember if it's the C2D I linked, or a faster one (it could possibly be the E8400).
I know Proximon has beat this to death, but is the 4-pin CPU power connector plugged into the motherboard in addition to the 24-pin motherboard power connector? I never really saw an answer to his question above. The board will not boot without the CPU power connector plugged in.
