As usual, I'm having a problem and hoping the good people of TH can help me.
I believe I'm having a motherboard problem. If I'm wrong, please move this post to the proper forum.
I have an HP m7260n desktop computer. It is about 6 or 7 years old but always worked fine. My father uses it for 3 reasons; chat on aim, check e-mail and scan slides.
The PC just refuses to stay on. It now shuts down for no reason even when he's not doing anything.
Naturally, I would think it's an overheating problem.
The fan works great. I cleaned out the little dust inside and changed the power supply. Same problem. Thought of changing the heatsink but it is as cool as it could be; since it's not hot at all, I don't think that's the problem.
I changed the CMOS battery. No luck.
I accessed the bios. Nothing unusual.
I used one of those PCI Diagnostics tools. Got the code FF which says the problem has to do with system booting.
Not sure if this is true though because occasionally, Windows does load up. Safe mode loads up also. It just won't stay on.
It's highly unlikely to be a virus.
It makes sense to me that it's a motherboard problem since everything else seems to be working fine.
Thanks in advance for any help!

try another power cable if that doesnt work try another Power Supply see if that helps
I did mention that I had already tried a new power supply.
However, I didn't do the power cable. I tried a new power cable and it still doesn't work.
