Current Events:

I've observed:

1. Random screen freezes (during gaming, and in the BiOS/during startup)
2. Horizontal black lines on screen.

Symptom 1 and 2 occurred while connecting the display through my gfx card, and I have only observed symptom 1 occur after removing my gfx card and connecting through my mobo.

Does this sound like a CPU problem or a Mobo problem? The GFX card could have a hand in it too, but I don't think it is the sole perpetrator considering the problem came even while it wasn't attached.

Any advice would be greatly appreciated.

Some History:

I built this computer last year, around black friday. It ran fine for a few months, then starting showing the following symptoms:

1. Randomly shutting down.
2. No BSOD/error report.

Sometimes it would show these symptoms under load (~100*c), other times it would not (39*c on idle). It got to the point where the computer wouldn't even make it past start-up. I figured it was a PSU/Mobo/heating problem, and after some testing, I decided to RMA the PSU.

It came back, and ran fine for a few days, then started acting up again. Same deal, except now I noticed that it would shut down even while in the BiOS.

ADDED: Temperature was still too high so I cleaned off the thermal paste with 99% Alcohol, and reset the 212 with a pea-sized drop of Antec Thermal Compound Formula 6 in the center of the CPU. Idle temps dropped to 29* (yay!) but the problem persisted (boo!).

So, I RMA'd the mobo.

It's been a few months since then and I haven't had this specific problem, but now I'm dealing with the problems under "current events."

you shouldn't be getting anywhere near 100c, especially since you have the 212 on.
are you doing any overclocking?

No, no overclocking.

I knew that the 39* on idle and 100* under load was too high. That's why I included overheating as a part of the pool of problems. I cleaned off the thermal paste with 99% Alcohol, and reset the 212 with a pea-sized drop of Antec Thermal Compound Formula 6 in the center of the CPU.

Idle temps dropped to 29*, but I don't recall temperature under load.

Sorry, should've included that in the history section.

It may have solved my first problem, but I only put that up there to give you a little history on the computer.

Unfortunately though, I am still experiencing the problem indicated under "Current Events" (copy/pasted below for convenience)

It's been a few months since then and I haven't had any problems of that nature. Now, however, I've observed:

1. Random screen freezes (during gaming, and in the BiOS/during startup)
2. Horizontal black lines on screen.

Symptom 1 and 2 occurred while connecting the display through my gfx card, and I have only observed symptom 1 occur after removing my gfx card and connecting through my mobo.

Any advice would be greatly appreciated.


The thing that throws me for a loop is that I'm experiencing this issue while connected to the GFX card, AND after I remove the GFX card and connect my display straight to the mobo.

I suspect there may be a problem with either the cpu or the mobo (or both).

The GFX card may also be a problem, but I am not sure. I will be testing the GFX card out my previous machine later tonight. Will post updates.

Any thoughts in the meantime would be appreciated.

I would love to check the events log, if the system gets past startup without freezing...
