Computer won't boot up but everything else powers on

post #1 of 13
Thread Starter 
Ok so i have a intel dual core with a gigabyte DS3L i built for a friend. The computer powers on and lights up and even the DVD drive opens, but I still can't get it to post. Its not the memory or GPU so i have narrowed it down to the CPU or motherboard. I think its the motherboard since its a little over 2 years old. I just wanted to hear some more advice with anyone else that has had this trouble. I would hate to rebuild this with a new motherboard if it was the CPU in the first place. Thanks in advance for any help

Have you tried resetting the CMOS battery? How do you know it isn't the graphics card?

I have run into issues that reseating ram and as madman says, reset the cmos battery. Those 2 things have worked for me most of the time. Can never be to sure with RAM.

Unplug/Replug everything... I have had cables/extensions loosen up and motherboard not getting enough power. Also what the others set reset BIOS and reseat RAM.

Did you test the PSU? I once had a client's PC do something similar and it was a PSU dying and not providing enough power.

remove everything but CPU (and cpu cooler) and one stick of ram. If it still doesn't boot, try each other stick of ram individually.

If all else fails, get the hammer out.

ok so i sat back down to figure everything out again and finally got it working. Reconnected the power connectors and took out 3 sticks of ram and still no post. Then i took out the CMOS battery for 5 minutes and got it back up and it finally posted with one stick of ram. Then I added one stick at a time and got to the last stick and last slot and it wouldn't post, so I put that stick into another slot and it worked. I put the last stick in the last slot again and it posted. Its kinda weird because i thought maybe the last stick was bad but it worked in another slot. The other stick also worked it the last slot so it isn't the memory slot i guess. Anyway thanks again for all the help. I'm running prime95 right now to see if I get any memory errors. +rep for all that helped, you guys rock.

Thanks. I actually just put a water system in my computer and it wouldn't boot late last night after being off for a few days of installing everything. The DRAM light came on my board and I thought I was hosed since it wouldn't post and I had done a lot of rigging. Took out the CMOS battery for 30 seconds, put it back in. BAM post. That little battery is boss.
