Hey everyone, I'm having major system problems and I need help. Here is what happened:

I was upgrading my computer today. I have a MSI 990FXA-GD65 motherboard and I installed a new AMD Phemon II X6 1100T. I also installed 8g more of ram which put me up the 16g of ram. So, I made these changes, hooked everything back up, and started my computer. Now windows will not boot. It says I have a corrupted boot configuration. I've tryed reinstalling windows but it won't work. Not sure what to do now could someone please help lol.

Try updating your BIOS and loading the factory default settings.

I have flashed my bios

Flashing the bios may or may not put it in factory default mode.
Pull the battery for the bios for 5 minutes just to make sure.

well, now I can't go into my bios or anything, it goes straight to try and load windows and fails everytime.

well, I have formated my harddrive from the dos prompt. Now I can't get it to boot from my windows disc.

First rule of upgrading: if you have a problem, stop and revert to the original configuration.

Second rule: if possible, upgrade a single component at a time.

It is now too late to ask if the original configuration still works.

Take the system back to original configuration - including the original memory.

If it still does not work, reat it like a dead system.

The following is an expansion of my troubleshooting tips in the breadboarding link in the "Cannot boot" thread.

I have tested the following beep patterns on Gigabyte, eVGA, and ECS motherboards. Other BIOS' may be different, but they all use a single short beep for a successful POST.

Breadboard - that will help isolate any kind of case problem you might have.

Breadboard with just motherboard, CPU & HSF, case speaker, and PSU.

Make sure you plug the CPU power cable in. The system will not boot without it.

I always breadboard a new build. It takes only a few minutes, and you know you are putting good parts in the case once you are finished.

You can turn on the PC by momentarily shorting the two pins that the case power switch goes to. You should hear a series of long, single beeps indicating memory problems. Silence indicates a problem with (in most likely order) the PSU, motherboard, or CPU. Remember, at this time, you do not have a graphics card installed so the load on your PSU will be reduced.

If no beeps:
Running fans and drives and motherboard LED's do not necessarily indicate a good PSU. In the absence of a single short beep, they also do not indicate that the system is booting.

At this point, you can sort of check the PSU. Try to borrow a known good PSU of around 550 - 600 watts. That will power just about any system with a single GPU. If you cannot do that, use a DMM to measure the voltages. Measure between the colored wires and either chassis ground or the black wires. Yellow wires should be 12 volts. Red wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts, violet wire (standby power supply): 5 volts always on. The green wire should also have 5 volts on it. It should go to 0 volts when you press the case power button, then back to 5 volts when you release the case power switch. Tolerances are +/- 5% except for the -12 volts which is +/- 10%.

The gray wire is really important. It should go from 0 to +5 volts when you turn the PSU on with the case switch. CPU needs this signal to boot.

You can turn on the PSU by completely disconnecting the PSU and using a paperclip or jumper wire to short the green wire to one of the neighboring black wires.

A way that might be easier is to use the main power plug. Working from the back of the plug where the wires come out, use a bare paperclip to short between the green wire and one of the neighboring black wires. That will do the same thing with an installed PSU. It is also an easy way to bypass a questionable case power switch.

This checks the PSU under no load conditions, so it is not completely reliable. But if it can not pass this, it is dead. Then repeat the checks with the PSU plugged into the computer to put a load on the PSU.

If the system beeps:
If it looks like the PSU is good, install a memory stick. Boot. Beep pattern should change to one long and several short beeps indicating a missing graphics card.

Silence, long single beeps, or series of short beeps indicate a problem with the memory. If you get short beeps verify that the memory is in the appropriate motherboard slots.

Insert the video card and connect any necessary PCIe power connectors. Boot. At this point, the system should POST successfully (a single short beep). Notice that you do not need keyboard, mouse, monitor, or drives to successfully POST.
At this point, if the system doesn't work, it's either the video card or an inadequate PSU. Or rarely - the motherboard's PCIe interface.

Now start connecting the rest of the devices starting with the monitor, then keyboard and mouse, then the rest of the devices, testing after each step. It's possible that you can pass the POST with a defective video card. The POST routines can only check the video interface. It cannot check the internal parts of the video card.

Thank you all for all your advice. I fixed the computer finally. After clearing my Cmos and taking the battery out for a while it let me bring up my bios and I booted from my windows 7 cd. Installing all of my drivers now and hopefully everything runs smooth from now on lol. Here is my system setup now.

Cooler Master HAF 932 case
MSI 990FXA-GD65 mainboard
AMD Phenom II X6 1100T
16g Mushkin Blackline DDR3 1600
EVGA SuperClocked GTX 560 TI
Hitachi Deskstar 1tb harddrive
Corsair HX850 power supply
Hitachi 42 inch LED TV for monitor.

As soon as I can sell my other computer I am going to buy another SC 560 Ti and SLI so that it can handle that big monitor better. Thanks again for all your help.

Wow, that's very similar to what I'm running. Except for a few things:

- Motherboard is Gigabyte GA-990FXA-UD3
- Case is Corsair Graphite 600T
- RAM is Corsair XMS3
- CPU is Phenom II X6 1055T
- Video card is dual EVGA Geforce 550TI 2GB
- Monitor is Vizio 42" LED

Well, My computer has been running good for a little over a week now. The only thing I see that's going on is that I get a little twitch and sometimes it even freezes for a couple of seconds on my TV when I'm playing games. The only 2 games I've been playing is Skyrim and NBA 2K12. Do you guys think this could be my video card or possibly sometime else. The freezing happens more with NBA 2K12 than Skyrim and I get more twitches in Skyrim lol. Any ideas?
