After one month my windows start showing BSOD every week once, i thought it's a software problem, but about two weeks my pc start to be very slow and keep crashing even if i browsing internet the internet browser crashed, so i decide to format my hard disk and install windows 7, when i boot from windows dvd and format my hard disk and start copying files after finish copying files it's show BSOD and restart my pc i thought from ram or hard disk, but i searched in the internet and i founded that i should try to make your cpu work with one core, so i changed it to one core, I installed the windows and everything fine but when i changed it back to 4 cores the problem back.

I returned my cpu, motherboard and ram to ebuyer for RMA and they said there's no faulty.

i didn't do over-clocking to my cpu or gpu

My PC Temperature idle :

CPU temp. : 24 C
System temp. : 38 C
GPU temp. : 40 C

Please help me

You read that you need to make cpu work with one core to install Windows? WHAT?

That's the most ridiculous thing I ever heard, don't believe everything you read please.

Check your memory settings in bios and make sure they are set to whatever the sticker on the memory says.

Browser crashes can be simply that, a browser issue. Try a different browser and I bet your problem goes away.

You should set your BIOS back to its defaults. Then run memtest86 on your ram.

If your RAM is ok via memtest then reinstall Windows from scratch - don't bother with any of that 1 core vs 4 cores thing, that is definitely NOT necessary. After installing Windows make sure to install the latest motherboard drivers.

Ok there are a variety of problems that cause BSOD even when installing windows. PSU could be bad, motherboard could be bad, HDD could be bad, video card could be bad.

Your idle temps are fine. Any idea what your temps were under full load (both CPU and GPU)? If you didn't install your CPU cooler properly your system may be unstable. Any ideas as to what those load temps are/were?

Do you have another video card to try?

Make sure the DVD drive is plugged into one of the SATA 3gb/s ports and not the SATA 6gb/s ports - on some motherboards they tell you this in the manual.

Have you tried updating the BIOS on your motherboard to the newest BIOS version?

Which port is your HDD in? Try a different cable and try it in another port - you have both SATA 6gb/s and SATA 3 gb/s ports on your computer. Try the SATA 6 ones first (only for the HDD not the DVD drive) and then try one of the SATA 3 ones next. Maybe you have a bad SATA controller or port.

Is there an error code on the BSOD?

what does the BSOD exactly say.?

you lose with that question...
check the specs in the very first posting to thread by the OP..

crazy issue you have, run a memtest and a HDD test (diagnostic).

remove all hardware and then clear CMOS on the motherboard;
then re-install RAM, try both sticks of RAM and attempt to boot.

if you get that far and ready to try to install windows 7 first use the advanced options of the install
and format the HDD, wipe it clean and start fresh.

asking once more - your HDD has a diagnostic program and it and it came back as the HDD is good.?

thank you for your help. i did all these thing and i am still don't know what the problem.

just want to know something why when i changed the cpu to one core the computer works fine

i think it's from psu today i notice the 12 volt is over load

edit:

i checked all the power connecter, now i can access to windows but when i run a program the computer restart without showing BSOD so what do you thing a cpu or psu ?

i don't know it's a coolmaster 650W

how did you get this, BIOS or monitoring software.?

i'll do a phd degree with this lol
finally it's the psu because right now i am monitoring the voltage Vcore under 0.700 and go lower to 0.500 and start showing crashing like windows defender crash or google chrome and when go up to 1.0 and go down quickly the computer restart
