Computer shuts down without a warning , I'm frustrated..

[tuvalu]

Hello,

My PC has begun making troubles lately.. it is randomally shuts down without any warnings nor any sort of screens whatsoever..

It just shuts down , I cant even install XP or WIN7 without having a shutdown , which in this case its impossible to even own a OS...

I don't know when the problem started , but I assume a month ago.

I can't even tell my PC build because it keeps crashing , however I ran a DBAN test yesterday and the computer ran for 20+ hours without any shutdown , does it mean something? I mean I can run programs like UBCD or HirensBoot , but if i try to install any sort of OS , the computer shuts down.

I have already thought of PSU , MOBO , RAM or heating problem , but I have no idea how to identify the exact problem...

I am desperate , I have no idea what to do.. I have no OS installed atm , IM LOST

Please help me.

I'm going to suspect hard drive here. Have you run any of the HDD diagnostics from Hiren's or SeaTools for DOS?

maybe overheat problem or virus ......
clean your pc by removing dust and/or check for bad fan
let me know

I'm sorry , whats DOS? I did run the HD sentinel program and it said 100% perfect , no errors at all. Can you give me more programs to check for hard disk errors / diagnosis tools

I will buy air compressor tomorrow , its late here.

How do I check for bad fans? they are all working and spinning when I turn my computer on.

Thanks for helping me , I hope we will pass this situation...

Can you please go over the history of this machine and what are your build specs (make and model if brand name)

edit: DOS is Disk Operating System, it is the most basic operating system for your computer and does not need any other operating system to use it - so Seatools for DOS can be used by itself
