I do troubleshoot pc's myself and gives advice to my friends about PC. But this one pulling my hair, one of my friend gave his PC to me for troubleshooting. I've checked the problem the PC keeps restarting for every 1 or 2 minutes.

So I booted the PC and I'm in the desktop after 5 mins it restarted automatically with no BSOD. I thought it could heat issue. So I entered into BIOS and looked at the temp, CPU temp was 80 C and it gradually increases to 90-95 C and restarted. So I reapplied the thermal paste and changed the stock cooler. Now the CPU temp is 60-65 C at BIOS and even at the BIOS setup it continues to restart at interval or 1 min as the temp remains on 60-65.

Then I tried these,

  • 1. Replaced with New PSU
    2. Replaced the memory
    3. Removed HDD
    4. CMOS cleared
    5. Cables connections are verified
At last I tried with PCI-POST card, while the system boots the POST card shows FFFF and no post code changed. I can see the Windows Starting and still it shows FFFF. And no Beep after POST but heard beeps when memory is removed.
So I'm suspecting the Mobo or BIOS.

Specs:
Mobo- Intel DH61WW
CPU- i3 2100
RAM- ADATA 2 GB
GPU- no GPU

if there no video card in the rig then your looking at vrm on the mb or power supply not holding. for vbrm heat issue or failure blow air onto the mb cool if it stays up longer it a heat issue. use a volt meter and check the legs of the power supply see if there holding.

I had searched about VRM problems and yes it says VRM fault can create repeatedly restarting problem. Thanks for the hint.
