It sounds like your power supply went bad. If you list your system specs, someone can help you find a replacement.
@ riider, there are two warranty claims on PCs namely: Manufacturing and Point of purchase. ILLUSTRATION:
Manufacturing Warranty: This is based on from the point of production date which can be checked online from PCs manufacturing site such as HP, DELL and many more.
Point of purchase: This is based on from whom your buy it from and date on invoice/receipt. NOTE: This is crucial when you wanted to buy a PC because you have to think of a product with after sale services, right vendor (usually authorised dealer) and time involved when support team are to fixed issues.
I would advised you tell us your PC warranty status in order to know where to help.
Thanks.
@ riider, there are two warranty claims on PCs namely: Manufacturing and Point of purchase. That depends on where in the world you live. In the UK there is only one date that matters and that is the date of purchase. Goods that fail within the statuary twelve months of purchase are the sole responsibility of the seller. The date of manufacture is irreverent.
It may be different where you live.
