Whenever I turn on my computer, it will run for a second, the screen won't start up, I'll hear the CPU fan running and etc. The lights turn on, but besides that if I click any button on the keyboard the computer shuts off. At first I thought it was the Power Supply, but because the computer started up and the lights started up I quickly realized that wasn't the problem. I know that the CPU fan starts up but I don't know whether that means the CPU is alright or not. And as far as the Motherboard goes. I m guessing its the motherboard because even the start up screen doesn't start. Can anyone help me figure out what is wrong?
Hope its my CPU because then I'll have an excuse to buy a new CPU with : D.
Here's the CPU I m eyeing.
Newegg.com - AMD Athlon 64 X2 4800+ Brisbane 2.5GHz 2 x 512KB L2 Cache Socket AM2 65W Dual-Core Processor - CPUs / Processors
Beats my old Athlon 4600+ 2.4ghz 89watts 90nm chip >.>
