Solved Random PC freezes

Tolis21 · Mar 21, 2012

hey there again. i bought today a new battery and replaced the old one, but i had a freeze again. what should i test now?

writhziden · Mar 21, 2012

Try to borrow a PSU of equal or better wattage and see if your system still experiences freezes. Borrow from a friend if possible.

Tolis21 · Mar 30, 2012

hey there again, i didn't have the chance to borrow a psu from a friend these days. Is there anything else i can check?

By the way i am using this surge that i uploaded. Is there any chance that this thing may be connected to the freezes?

writhziden · Mar 30, 2012

If it has a short, it could cause freezing. Why do you suspect the surge protector?

Tolis21 · Mar 30, 2012

As i say in one of the first posts, when i returned from the summer holidays 1 year ago my pc was working but it gave no signal to the screen. and when i sent it to be fixed and they told me that it needed a reset on bios, they also told me that the power in this town many times goes down, because of lightings and stuff and maybe that's why the problem occured. so my father bought the surge protector. So i thought it may be connected because after i bought it and got my pc back the freezes started.

It may also be due to the power surges experienced before buying the surge protector. You may have a component in the system that was damaged by a surge prior to having it fixed. You either have three bad RAM modules (unlikely in most cases, but possible if they were damaged by a power surge), a bad motherboard, a bad CPU, or a bad PSU. Let's do some hardware testing to see if we can track things down a little:

If you are overclocking any hardware, please stop.
Monitor temperatures during the following tests.

Use the following programs to monitor the temperatures.
- Real Temp is a good CPU temperature monitor.
- Speccy - System Information - Free Download will monitor all hardware temperatures.
- HWiNFO, HWiNFO32 & HWiNFO64 - Hardware Information and Analysis Tools can be inaccurate for CPU temperatures, but is a good program for GPU temperature monitoring.
- Use FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net to test the graphics card GPU. Let it run until the GPU temperatures even out or until the GPU temperatures reach a dangerous level (you can find the max temperature for your card on either the nVidia or AMD sites; if you are not sure, ask us). Then use the |MG| Video Memory Stress Test 1.7.116 Download to test your graphics card memory. Let the memory test run for at least seven passes; the more the better.
- Run http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.html to determine any hardware problems. Run all three tests for a few hours each. If you get errors, stop the test and post back here.
- Follow the steps for doing a CPU stress test using IntelBurnTest

ok i will start checking temperatures now. by the way i am reminding you that most of the freezes (9 out of 10) happen within the first 30 minutes after turning the pc on and rarely a freeze happens after my pc is running for hours. I had my pc running overnight many times and no freeze happened afterwards.

I'm not sure you told us it only happens in the first 30 minutes of turning on the PC... That usually means voltages are not set up properly for your RAM.

Download and install CPU-Z and Upload screenshots of the CPU, Mainboard, Memory, and SPD tabs. In the SPD tab, upload an image of each slot.

Also, go into your BIOS and post all Voltages (CPU, RAM, NB, IMC, etc.) and all RAM settings (timings, frequency, etc.)

Thanks to Dave76 for help learning RAM Stability

hey. i am uploading the screenshots from CPU-Z. In the BIOS i couldn't find the information you told me to. What i found that was reffering to voltages was this :

In Power->Hardware Monitor tab

Vcore Voltage [1.304V]
3.3V Voltage [3.296V]
5V Voltage [4.968V]
12V Voltage [11.816V]

Also in Advanced-> Configure System Frequency/Voltage it didn't show any info, but all the options were set on Auto.

writhziden · Mar 31, 2012

Try bumping your northbridge voltage to 1.55 V and manually set your first four RAM timings in the BIOS to 5-5-5-16 instead of 5-5-5-18. Do not change any other settings. See if the system is more stable.

Scratch that. Update your BIOS from the motherboard site (NEVER INTERRUPT THE FLASH OF THE BIOS VERSION). ASUS - Motherboards- ASUS P5K

You have a very old version of the BIOS, and that may be part of the problem.

i have win7. so in the os option i chose other because it doesn't have win7. i downloaded ''P5K BIOS 1201'' and in the zip there is this file ''P5K-1201.ROM'' which i can't open. is this the correct update? and if yes how can i run it?

writhziden · Apr 1, 2012

You need to also download the BIOS utilities and run the BIOS update tool in Windows to use the ROM you downloaded. The ROM you downloaded is correct.

ASUS - Motherboards- ASUS P5K -> Download -> OS: Others -> BIOS-Utilities -> Afudos BIOS update tool V2.36

Tolis21 · Apr 2, 2012

i downloaded the Afudos BIOS update tool V2.36 but when i try to run it i get this message i uploaded. what should i do?

writhziden · Apr 2, 2012

ASUS - Motherboards- ASUS P5K -> Download -> OS: Vista 64bit -> BIOS-Utilities -> Afudos BIOS update tool V2.36

Tolis21 · Apr 2, 2012

ok i will try this one. About the P5K BIOS 1201 file, should i get it for Vista 64bit or other os?

Tolis21 · Apr 2, 2012

i got the same message with the vista 64 bit Afudos BIOS update tool V2.36

writhziden · Apr 2, 2012

Try the Vista 64bit ROM. Also, you may need to right click the executable, click properties, and go to the compatibility tab. Run this program in compatibility mode for Windows Vista.

Tolis21 · Apr 2, 2012

I changed the compability mode to Windows Vista but i am still getting the same message.

writhziden · Apr 2, 2012

Did you run it as administrator? Right click -> Run as administrator.

Tolis21 · Apr 2, 2012

I run it as an administrator and i get this message : Windows cannot find 'C:\Users\Tolis\Desktop\AFU236U.exe'. Make sure you typed the name correctly, and then try again.
