I have already tried every possible solution of fixing my computer but it seems I'm getting no where. I'm the one fixing computers when regards to my family and friends. Fixing computers is my part time job. Now I have a problem with my own computer and was not able to resolved the problem.

My problem is my pc keeps restarting and I already replace some of the parts and still keeps restarting sometimes its getting a blue screen even though its recently reformatted.

My Specs:
Emaxx EMX-MCP61M2-iCafe MOBO (Brand New) replacing the old EMX-MCP61S-AVL
600 Wtts Power Supply (Brand New) Replacing the old 500 Wtts
My Old P6600 3.2 Ghz Processor
My Old Seagate 40Gig Hard Disk
My Old 2gig RAM

I Have already removed some of the parts to see if the problem would be fixed...
I removed the video card, floppy disk, cd rom, second 1Gig RAM, and the second hard disk

Troubleshooting steps that I have done:

- I have already reformatted my pc for several times and tried to switch from xp to windows 7 and see if it will work and still the same.
- Installed all the drivers
- Run BIOS to fail safe mode
- Replacing thermal paste and it runs on 45 degrees to 48 degrees temp (No signs of overheating
- CPU Fan is working
- Scanned the hard disk by doing it through command prompt "checkdsk" and fix some problems
- Undo the partition of my hard drive just to be sure
- Scan the RAM with MemTest86+ and no signs of errors and passed three test
- Tried to removed the RAM and there's a beep and put it back again
- Jumpers of my hard disk is connected right
- Changed CMOS battery
- Removed the entire parts to the case just to be sure that there's no grounded
- Run In Safe Mode and the pc still would restart
- Checked the Event Viewer but it says critical error kernel computer restarted without shutting it down properly

I have already read every thread in this forum and it seems none of those help. I nearly threw my unit to the garbage and Im already in a point of loosing hope to fix computers again.

By the way, my processor is doing something, it makes noises when I go the the bios to change the time setup but when i go to the other settings like security and power setup the noise would disappear. Only in main setup. I wonder if my processor is already damage but the processor is the most durable part of computer to be broken. I have no idea what signs to be able to detect if cpu is damage... As far as I know, if the processor is broken the computer will not boot.

My Hard disk socket is a bit loose, sometimes its getting a boot failure (cannot find boot sector). It temporarily fixes the problem when I connect the power cable tightly and it will come to windows. So if the HD will fail windows will hang or after the restart post msg will be "cannot find the boot sector"

So the problem is either the MOBO, Hard Disk, RAM, PSU, or CPU... bought new NEW MOBO, PSU.

I Hope You Could Solve My Problem.

we will start with 2 thing first check the cmos battery is she still deliver the voltage she should use a votlmeter or battery tester the second one since you use checkdisk and it fix some error i would use use the drivemaker test tool ,this seams to me that the drive gone let you go so if you could save all your needed data .

I use the old psu and the computer is restarting, and bought a new one to think that maybe my old psu is the culprit. Thinking that the old psu is lacking its voltage already so i bought a new one. Same result. Restarting! Sometimes it will power then the fan will spin for a couple of seconds then turns of again. checked the temp in bios and no signs of overheat. Replace thermal paste with the new one. Same results

I will try to use this program and let you know the result. By the way, the time display is still the same and no alteration when I set it up. If I will remove the cmos batt the time will change and then set it again after I put back the battery. I also tried to remove cmos battery for 5mins and tried to boot it and also tried change the jumper just to be sure in order to reset the bios

Yes it does... I have experienced that already that if the cmos battery is weak sometimes the clock will reset back and you need to put the current time again.
