Hey Everyone. Ive had this system for almost 2 years now and Ive run into a big problem, Ive posted on several forums but so far I havent found a solution so here I am. Here are my system specs:
Intel DP45SG mobo
Core 2 Quad 9300
8gb Corsair XMS DDR3 1333
EVGA GeForce 260 GTX
Intel 80gb SSD
500gb Seagate Sata HD
850w PC Power and Cooling PSU
Windows 7 Ultimate
And here is my problem:
This system has run great since I built it in January 09. I bought an SSD in January of this year which made it run even more ridiculously fast. I had no issues adding the SSD and I dont even think I've had any errors (other than your occasional software crash) in a long long time. However, from the day I built the system I never could get the memory to run at 1333, it always defaulted to 1066. Manually setting the memory timings and speed resulted in bluescreen so I just left it at default all this time. A few days ago, I was updating my onboard sound drivers when I noticed that there had been several bios updates for the motherboard since I got it. After reading through the updates, it showed that some memory issues had been resolved, so I decided to update the bios. I've done bios updates before so I wasnt expecting to run into trouble. I did the bios update using the ISO onto a CD, I used the latest bios which was version 125. The bios updated successfuly and I confirmed it had been updated in the bios menu.
After updating the bios and confirming, I rebooted and thats when what im going to call World War 3 began. The PC turned on, POSTed fine, beeps once (just like it always has after post completes) then immediately went to a blank screen with a flashing keyboard cursor. I let it sit for a while and then decided that it had hung long enough, so I rebooted. Same thing happened again. I double checked all my bios settings, everything was correct. The Bios recognized my drives, the event log had no errors, etc.
After trying to get into it several times, I decided I better backup whats on my drives that I need cuz I was going to reinstall windows. I backed everything up on the PC using some boot software I have, everything went fine. Got all the files I needed off of it. Then I reinstalled windows. Booted from my windows disc just fine, went through the full install, pc restarted. Post, then it went into the windows setup running from the hard drive. Everything there went fine too, set my username, configured, etc. Computer restarts, posts and then back to the blank screen with the blinking cursor.
So here I am 3 days later, I've tried 4 different bios, Ive reset the CMOS 3 times, Ive unplugged every device from the PC, I've tried just 1 hard drive, Ive tried another hard drive. Ive tried every which way to boot by selecting the drive manually, swaping sata ports, disabling all the onboard devices (lan, sound, esata, etc). None of this has worked.
At one point I actually did get into windows, but only once and it was extremely weird the way that it happened. After installing windows to one of the hard drives, and getting the same result, I hooked up another hard drive and installed windows to it. After the initial setup of windows, after rebooted and after post, I got a windows boot screen that asked which installed windows I wanted to boot to. I chose the one I had previously installed on the other hard drive and it actually booted up fully into windows with no problems. Thinking it was a fluke, I decided not to start reinstalling all my software and I restarted the PC to make sure. Sure enough, blank screen with blinking cursor again.
Currently, I've been unsuccessful. I've repaired many computers, I even worked in a shop for several years and never came upon anything like this, although hardware was never my specialty. A friend of mine who is still in computer repair says that maybe the BIOS i originally updated to might have had a firmware update for the sata controller and it may have corrupted somehow or is incompatible, and is causing it to not give over control to the windows install. He thinks this because even though the setup loads multiple times, its different than when windows actually loads because it uses a different kind of boot to ensure that the setup runs on the next boot, after installing windows. Which I can see the logic there.
The other thing is, I am not able to go back to the original bios this board came with, which is version 088. Its not available on the intel website and I cant find it on the web either. The closest one I could go to that was after my original was 093, and that one I couldnt get the dvd drive to load a disc, it kept giving an error that no disc was present.
Does anyone have any idea on something I can try to fix this? I am desperate to get this thing working again. This is my main PC that I do all of my gaming and everything else on. Im currently posting from my other system that's just an older PC I use as a file host.
If anyone out there can help, please dont hesitate!
