computer keeps shutting down

[mirtz]

i am having a intel dual core processor, mercury motherboard, 1 gb RAM and a widescreen moniter.

The problem is my computer shuts down automatically for no reason.
this happen when using adobe acrobat, or when watching videos on sites like youtube or when playing games like counter strike1.6, whereas GTA works fine and using foxit reader in place of adobe works well.
i don't uinderstand why this is happening, my kaspersky doesn't show any virus. is der a hardware problem??
when i used vista these problem continued but a blue screen appeared showing dumping of physical memory and then it restarted. now i am back to XP.

Any software or hardware changes recently?

Nope .. infact i had formatted my whole system 3 months ago for same "shutting down"  reason but still da problem persists..

if that 67 degrees C is the cpu, that's way too hot. Check your heatsink, fan and cooling.

Please stop writing da when you mean the. This is not a gangsta hangout.

ok i checked all tthe components.put them all under a table fan, again put them back and tthis is the result i got with speed fan
temp1 50c  fan1 4561rpm
temp2 64c
temp3 45c
hdo 44c
is this heat inside the CPU causing the PC to shutdown or is there any other problem??

Well, as what Dias said, your temp readings are too hot..

And also may we know your specs? >> http://www.computerhope.com/forum/index.php/topic,33586.html

Try to check also if your processor have thermal paste in it. I experience this one with a computer in our company. I applied a new thermal paste to its processor and problems were solved.

Thanks!
