I was wondering if you could help me with the following:
Last Saturday I installed my new motherboard from Gigabyte, the 990FXA-UD5 into my computer, together with 8 GB of
RAM, two new sticks of 4GB each in the in the manual advised slots, 1 and 2. When I powered it up, it gave me three
long beeps, cycling in pairs of three and it would just sit there at that. So, after reading on Inet to reseat the
sticks, that's what I did, to no avail, unfortunately. Then I took everything out and I reseated everything again.
This went on until I had reseated the RAM into the slots no. 1 and 3 and then it gave me one short beep and booted
up fine. Next time I rebooted, it gave me the three beeps again, so the whole cycle started again, until I
ultimately had seated hem again in 1 and 3 and it seemed to be working again. Then Win7-64 didn't feel like
installing on my SSD, so I took out all, except one of my two Graphic Cards and only the SSD plugged in. The three
beeps were back again. Only this time it was weird: when I had the case laying on its side, it booted up find, but
when I put it back on its feet, the three beeps were there. And they were gone as soon as I laid it back on its
side. Finally, I got it to boot while standing up. Then, yet again, sth strange happened: I merely tapped on the
top of my V8 CPU fan from CM (it was just that),powered it up and it booted and even Win7 now decided to install on
the SSD. After the install, I plugged everything back in and it worked. This went fine until the next day I had to
visit a friend and stayed away for a few hours. Upon returning home, I powered up my machine and the three beeps,
followed by a short startup beep, were there.
What happened since then is following: I get three cycles of three long beeps, followed by a short ("normal") beep
and after that I get the normal startup beep only and the machine boots up normally. All fine, weren't it that the
system seems to be unstable and freezing up irregularily, I get kernel power error msgs and today while restarting
after yet another freeze, I suddenly get the Main Bios Checksum error! msg which then backups from the other bios.
Weird with this is that it has set my version of the bios back to F3, where I had just flashed it to version F9 two
Can anybody tell me what is going on as I don't know what is happening? The system is not overclocked and runs at
stock values, the memory, although 1600, runs at 1333 unganged mode. I am suspecting the RAM, but it may as well be
the PSU, although @750 Watts it should be strong enough to run my system (correct me if I am wrong). Here are my
- Motherboard: Gigabyte 990FXA-UD5;
- CPU: Phenom ii x2 550 (soon to be replaced, I guess);
- Memory: GEIL "Dragon Ram" 8GB (2x4GB) @ 1600 (specs; runs at 1333);
- HDD's: 1 SSD OCZ Agility 3 60GB; 2x Samsung 500GB; 1X Seagate 500GB;
- Graphics: 2x ATI RADEON HD 4650 (I am not really a gamer, so these should satisfy my needs where the occasional
game is concerned);
- SoundCard Soundblaster XFi Xtreme Music (soon to be replaced)
- Optical Drives: Generic DVD-ROM; LG DVDRW
- PSU: 750 Watt Thermaltake Toughpower
If you would be so kind to let me know what the issue(s) is (are) that I am experiencing and what I can do to fix
it, I would greatly appreciate it. Thank you very much!
Sorry about the long story - I just felt that I needed to
add what happened leading up to my current state.
