Ok so i have a computer in that was hit by 3 power spikes in a row. Well i thought the memory was at fault but i am out of ideas The computer has four 2 gigs sticks. It is an hp, It is blue screening. Also the system had to have the os reinstalled. windows vista x64. Also the video card had to be replaced.
So far i pulled out all the memory and tested them one by one. stick 0 works fine in bank 4 and 2. stick 1 did not work in any slots, the same goes for stick 2 and 3. If i put stick 0 in bank 4 and stick 1-3 in bank 2 the system boots. I tried every slot with every memory stick and it wont boot if i have more than 1 memory stick in at a time, of the original memory. I can how ever put a memory stick 512mb of the same speed and type, in any slot with any of the stock memory and it will boot, as long as it is one stock stick and the 512mb stick. If i do more than that it blue screens.
Now the wierd thing. I reinstalled vista 64, with all 4 memory sticks in, so the full 8gigs, and the install went perfect. Until 5 minutes into the desktop,and the system rebooted and blue screened. That is when i started testing the memory. The video card is good. The blue screen error is 0x00000e7 i believe. I am away from the computer, and wont bee in to work until tomorrow.
Now upon reading it could be a video adapter, driver, etc... But why would it boot when changing the memory.
Now, could there be a short that happened when the computer was hit by the power spikes? Or could the voltages be causing the issues? I have not checked the voltages yet, nor did i test the power supply yet. I will test that tomorrow, but i really need help because we are stumped.
