Computer randomly freezes

I have the same problem.. When you play games, does your screen when it happens gets spotty or something with white spots or w/e, and does your sound keeps reapeting then, like 1 sec of it?

Do I have the same problem with PSU?
My specs:

OS: Windows XP Professional SP 3
Processor: Intel Core 2 Quad Q9550, 2666 MHz (8 x 333)
RAM: 3328 MB (DDR2-800 DDR2 SDRAM)
GPU: NVIDIA GeForce 9800 GT (1024 MB)
PSU: 550W Frontier ATX-550

Hi neko ceko and welcome to TSF. Yes I would say that your PSU is definitely not up to scratch. You should be using a PSU like a Corsair 750W to power a 9800GT. Please note, the PSU you buy must be a quality brand like the ones mentioned in this thread. Low quality PSU's will damage your system over time, and when they go completely, can take your whole system with them.

Thanks...
The company which made my computer should of know that.. I mean, I even brought my computer to them 1 times about the problem and they gave it back saying everything is working fine.

that is because they know crap about PCs
any PC expert who knows nothing about PSU does not deserve to be an expert

Yea..

Check the temperatures and +12V reading in BIOS, and during gameplay with SpeedFan. Post back with both sets of readings so we can compare idle and stressed performance.

If SpeedFan doesn't show the graphics card's temperature, use RivaTuner or nTune in the nvidia control panel.

Also, enter your full system specs into this power calculator and set Capacitor Aging to 25%. Click the Calculate button, then add 40% to the total to allow for PSU inefficiency.

Are all your device drivers up to date? (graphics, sound, mouse, etc)

They just put a really low quality PSU to help power your other high end components. Do you really trust them this much? Experts are not a free commodity to stick beside someone's name just because that person was hired by a computer company.

You don't need a Corsair 750w to power that 9800GT, a Corsair 650w should be fine.

I'll use Everest for temperatures since this program looks buggy to me.. Not everything is showen etc...

When not playing:
Motherboard 36 °C (97 °F)
CPU 36 °C (97 °F)
CPU #1 / Core #1 46 °C (115 °F)
CPU #1 / Core #2 42 °C (108 °F)
CPU #1 / Core #3 44 °C (111 °F)
CPU #1 / Core #4 41 °C (106 °F)
GPU Diode 43 °C (109 °F)
STM3500418AS 31 °C (88 °F)

and

+12V: 1,79V

Now I'll try when playing games. (This is when playing only a minute, since I can't play any longer without freezing. If you want I can check it with some games that I can run without problems (the older ones etc.).

Motherboard 37 °C (99 °F)
CPU 46 °C (115 °F)
CPU #1 / Core #1 59 °C (135 °F)
CPU #1 / Core #2 55 °C (131 °F)
CPU #1 / Core #3 55 °C (131 °F)
CPU #1 / Core #4 52 °C (126 °F)
GPU Diode 45 °C (113 °F)
STM3500418AS 31 °C (88 °F)

+12V: 3,26V

These look high to me Oo
But I don't know much about this.

Oh and thanks for the info McNinja

What are the BIOS readings? Everest is showing +12V at 1.79V and 3.26V. Both are incorrect as your computer would not even start if it was really that low. For a healthy PSU it should be between 11.4V and 12.6V at idle and under heavy stress from a fullscreeen game.

The temperatures you've posted look ok, but what about the graphics card temperature?

What total did you get in the power calculator?

Are all your drivers up to date?

neko_ceko

Actually, that was not Everest that was SpeedFan. In Everest I saw that its 12V or something, and I compared it to speed fan, and I was like "*** this is probably not the thing he was talking about" so I used the one from SpeedFan.

And all drivers are up to date, and sorry I forgot about the calculator. I'll do it later when I have time.

I just noticed it also happens when I delete a PC account. And sometimes when I listen to music. But it doesnt freeze, but it restarts mc PC and blue screen appears for a sec.

redo the paste on the cpu with some arctic silver

http://www.arcticsilver.com/arctic_s...structions.htm

turn off the auto reboot
control panel /system/advanced/startup and recovery settings
then untick the auto reboot box
post any bsod error messages the computer freezes on in full

post the voltages listed in the bios they are the most accurate

neko_ceko

Sorry, but I really don't have time to do that now. I'm gonna get a new PSU tommorow, so if it keeps happening I'll get back here-

neko_ceko

Fixed.. The problem was in the graphic card. Factory malfunction. They changed the card and everything works fine now :)

Thanks for posting back with your solution.
