Specs: Windows 7, 2gb
So my friend asked me to take a look at his Desktop PC
Well I gave it a try since I havent had any problems fixing any PC
But this one is new to me
It's stuck in a boot cycle.
The HDDs are fine since I've tried them on my PC
The data is all there and it boots on my system
I tried putting on my HDD on his system but still stuck in the boot cycle
It wont even boot from the CD drive
All drives are detected in BIOS.
all look fine.
I even restore the defaults of the BIOS

I am lost..

Run Memtest from a bootable CD to test the memory for errors.
Check all important BIOS settings like SATA settings, bootable drive, boot order, CPU and RAM settings, graphics/PCIe settings, etc.
Make sure CPU heat sink is securely mounted (without removing it) and make sure that the fan is spinning when you start the machine (if the heat sink moves or if you unlock it, you will have to remove it, clean off the thermal compound, and replace the compound with fresh compound -- ask for instructions for his CPU).
Disable automatic restart to be able to read error messages.

Overheating CPU or failing power supply, possibly bad RAM. What happens if you try to boot with no HDDs attached? Or did you try booting off a LINUX live CD?

If there are 2 sticks of ram or more take them all out but one, see if it boots. If not swap out the one stick with another and try again. Otherwise the guys have posted the common issues. Bad ram, faulty power supply and heat.

Yeah I think it's a hardware failure
I checked all of the BIOS settings
It's all fine
Swapped with my RAM which I currently use so it's definitely fine
Booted with no HDD or any drives attached but nothing happen
It suppose to show 'No media selected' etc
instead the system just reboot..all over again
As for the PSU , should I swap with mine?
Mine is powerful enough to run his system

You're not posting any useful info. How about your friend's system specs? The CPU temp from the BIOS? The make/model/wattage of the power supply? Did you try booting off a Linux disc?

Not all Cool Master power supplies are that great, list the model number.
Try another power supply.
You did not comment on the internal inspection above. Look for anything loose also.
Make sure both the 20/24pin connector and the 4/8pin connectors are plugged into the motherboard.
Make sure that the motherboard is held off the case by the spacers/studs and all of the indicated holes have a screw in them.
Make sure there is not a build up of dust in the system.
Make sure wires are not pinched between parts or running over sharp metal edges (shorting).
