BSOD on startup and eventually in windows

[solidsnakeusa]

Hello I've been trying to fix this BSOD problem forever. I'll run a memtest after this post.

I ran the program in the post stickied in this board and I've attached it with the performance monitor html as well.

as for the questions

Is Windows 7 . . .
- x86 (32-bit) or x64 ? x86 (32bit)
- the original installed OS on the system? It's a custom built machine the original windows i installed on it was windows xp but this is a fresh install after a full reformatting of my hard drive.
- an OEM or full retail version? Retail version
- What is the age of system (hardware)? The ram is about 4 years old. the CPU, motherboard, and videocard are about a year old. The hard drive is probably about 2 years old.
- What is the age of OS installation (have you re-installed the OS?) Should be less than a year. no i have not reinstalled the os

Ok iIran memtest86 for 2 hours and it came back clean. There were no errors.

How many passes did it make? It needs to make seven passes minimum. That usually takes 6 - 8 hours.

 

[solidsnakeusa]

oh sorry guess i misread thought it was 7 tests it ran 3 passes i'll run it over night.

 

[CarlTR6]

No problem. Many times, errors do not show up in three passes. The RAM has to be stressed longer than that. I recently saw a case where errors did not show until the 13th pass and that turned out to be mismatched RAM.

 

[solidsnakeusa]

ran it for 8 1/2 passes over 7 hrs no error. all my ram are the same so i doubt it will be mismatched

 

[solidsnakeusa]

it seems to only happen on start up once i can get into windows i'll generally be fine until i turn it off and turn it on again

 

[CarlTR6]

Run Memtest from a cold boot the first thing in the morning and see what you get. It could also be a power supply problem. Do you have access to another known good PSU you could test with?

 

[solidsnakeusa]

i should have one in the garage somewhere i will try it out. i did suspect it might be the problem since my video card's minimum req. is right on my psu's output.

 

[CarlTR6]

That makes it a good possibility. A PSU's output declines with age.

 

[solidsnakeusa]

i ordered a new one and it will be here tomorrow. the one in my garage is only 500w not enough to power my video card. i'll let you know tomorrow.

 

[solidsnakeusa]

i pulled 1 stick of ram out (2 left now) and it boots right in. so i assume it's a ram problem.

 

[Jonathan_King]

Keep in mind the stick of RAM you pulled accounted for some of the power draw, so it still could be a PSU problem.

[CarlTR6]

I agree with Jonathan, especially in light of what you posted about your PSU being marginal for your graphics card. After you get your new PSU, you can check your RAM.

 

[solidsnakeusa]

thanks for the help guys i put in the new psu and it booted right up with all 4 sticks of ram back in. no blue screen for about 4 hrs now not since i put it in should be good to go i think.

That is really good news! Congratualtions. Please post back in a couple of days and update us on how your system is doing. I hope we can mark this thread as solved.
