automatic shut down

[praveen200s]

i have DELL inspiron 1525
with windows vista home premium
processor -intel(R) core 2 duo T5450 1.67GHz
RAM - 2gb
i bought it in April 2008, it worked fine till Dec 2008.The battery life of my laptop is over so I use it on direct power.But now it shuts down automatically when ever I try to play any simple game or do multiple tasks at a time.I don't know what is the problem....whether it is due to processor heat up or anything else?
I would realy like to know if there is any problem in the processor cooler can i claim for repair from DELL.It has a 1 year warranty.

Be in touch with dell tech support. It should be within warranty and your problem on dell laptop (for any infact) is not supposed to happen. They will arrange for a replacement.
