Failing computer but not sure why

Specs: Windows Vista
My problems started after my initial Motherboard died. I thought oh well I can always get a new mother board nothing hard. So I did just that. When I booted up my computer after installing the new Motherboard it would freeze. I tried booting it in safe mode and could move for a bit but not much progress before it froze.

I went for help. My one friend told me that since I was using windows I would need to re-install windows, due to the new Motherboard. I had no problem with this either. My music and important files were on an external Hard Drive so re-installing windows was just a little more time for me. I tried installing windows and the same thing happened. At this point I thought maybe it's just Vista being Vista. So I went a purchased another hard drive and attempted to Install windows on that hard drive. Same problem.

I decided that the Motherboard I had Purchased was Dead on Arrival. I also ran into a small bit of money and decided to purchase a new CPU for the of it. I ran windows on the new Hard drive that I purchased and all seemed to go well. And then it froze again. I tried adjusting the RAM voltage but no luck. A couple of times I've gotten the installation to complete itself only for my monitor to not pick up signal from the video card.
Below are the Specs of the computer I'm trying to run.

Thermaltake TR2-500w

Intel: Gigabyte Ep45-UD3P

Intel: Core 2 Duo 2.8 ghz

Video Card:
Nvidia 7800 GT

Hard Drive:
Maxtor 1 TB Sata

Consair XMS2-6400C5 4 GB (1 GB Per stick)

Attempted OS:
Vista Home 32-bit

Your troubleshooting skills are horrible. Randoming replacing parts is not the way to fix things.

What was wrong with the original motherboard? The replacement definitely was not DOA, if it was, the system would not have booted up at all. Have you ever tested your RAM with memtest86? If not, that's the place to start. Also, if your 2.8GHz CPU is the E7400 at 1066MHz FSB, try dialing down the RAM speed to 266MHz (533MHz DDR) to match the CPU. You should also check the CPU temp in the BIOS to make sure it's not overheating. It should be 40C or less at idle.

Replacing parts not he most effective way of fixing computers but it is the easiest. Please don't treat me like I don't know computers. If it was a heating issue bios would have mentioned it the dozens of times I started it up. I tested the ram today by putting it into my room mate's computer but I will try and turn down the Ram speed.

"If it was a heating issue bios would have mentioned it the dozens of times I started it up." Not necessarily-if you can get into the bios, check the cpu temps and also the shutdown temperature. If it was heating up too much, the bios would have shut the computer down to protect the cpu. You shoul,d also try booting up with just one stick of ram.

While randomly replacing parts is not the best way to troubleshoot computers, I'm not going to go as far as to say that "you don't know computers." IMO, I think that that's a rude and unhelpful comment to make. I was using computers for 6 years before I really began learning how to troubleshoot the hardware side of them.


Do you by any chance have any PCI/USB devices installed? If so, remove them. Also try booting with one stick of RAM at a time installed, making sure the RAM is seated firmly in the slot and that the plastic clips on the sides of the RAM are all the way up (you may have to push them up with your finger). If it freezes with the first stick installed, turn off the system, unplug it, ground yourself, remove that stick, and try the second stick. If it still freezes, just for kicks, try the 3rd and 4th sticks individually. If you still have problems, install one stick in the second RAM slot (some motherboards allow this, some don't; if yours doesn't, it will emit a beep code that means no RAM and will refuse to boot). If it boots again but still freezes, try a different stick one at a time in the 3rd and 4th slots individually. RAM and RAM slot problems are very common. Your symptoms highly mimic RAM and RAM slot problems.
