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

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?

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

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:

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.)

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.

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.
