Random shutdown?

post #1 of 7
Thread Starter 
My girlfriend has a clunker comp..

AMD Thunderbird 1.1GHz
512MB RAM
Radeon 9000

The rest is generics. She's been having trouble with 3D games (Guild Wars to be exact) freezing on her, and leaving her to restart. She just bought Fable, and now sometimes her computer will go in what appears to be standby mode. The monitor shuts off, and the computer becomes unresponsive that is only curable by restart. At first I thought it was her CPU temps. She was idling at 46C and stressed at 53C with a small HSF of an unknown brand. I idle at 38C and stress at 47C, so I'm thinking her temperatures are causing the trips. Apparently the CPU won't go critical until 95C.

I've tried..
-New HSF; only dropped temps a few degrees.
-New drivers.
-Running SuperPi to 32M; temps got hot, but it never crashed.

The settings she's running are completely conservative regarding her video card. She gets a fairly reasonable frame rate. And actually I just got off of the phone with her, and she's been playing Fable for 3 hours solid at 53C and it hasn't done it.

2 questions:

1) Any other ideas what might be causing this?

2) If the processor is 'critical' at 95C, would a moderate overclock (1.1 to say 1.4 or 1.5 at these temps be alright? What should I try to stay under?

Do you have a spare PSU around? I would try running with a different PSU.

The thunderbirds get very hot, but can take alot off heat too.

Random shutdowns are actually never random XD

For instance if your computer suddenly starts consuming lots of power + your psu can't take it = Your computer will just stop with or without resulting damage.

It can also be your ram BTW, if the timings are too tight you get random shutdowns too.

Another idea that is probably way out there is it could be the mobo. I had an old mobo that the header for the case switch went crazy and the thing would randomly shutdown(and turn on in the middle of the night ). Fortunately, the thing had an override so you could just use the psu switch.

Like I said, not likely to be the problem, but just throwing it out there.

It's funny that you guys mentioned the PSU. I actually have no idea what she has in there now, but I put in the old PSU that came with this case (used to hold an eMachines, but I kept the name I gave it) which was a 400W. A few days after it's in there, her HDD goes bad, and everyone points their finger at me. Anyway, I'm not to sure if her dad (also a computer dork) put in a new PSU or not. He has a tester, so I don't think he would put in a bad one. =/

And I'll definitely check the timings out. She has two 256 sticks in there now, if I'm not mistaken.

tlan, thanks for the heat info. I'm going to do a 132FSB with a 11x multi and see what I can get. The motherboard can go up to a 14x multi, I think. Would that have any adverse effects?

And they had to write on the CPU to unlock the multiplier. PLEASE tell me that they had crappy coolers back then, and that's why they think a 100MHz overclock is so extreme.

I'd also say PSU or RAM like everyone else is mentioning. Did the lockups stop with the other PSU?

My old 1.4GHz Thunderbird core I had ran at 87C full load... and was stable. That is... until the PSU fried and ruined the entire system.

I'm not sure if Guild Wars was freezing before the 'new' PSU. I'll have to ask. I'll also have a run with Memtest.

87C is quite hot. But if you say it won't melt on me.. If the PSU fries on her, then I'll just build her a budget build.
