Need more power!

[Agent Ify]

Hey,

I posted yesterday about my new wifi card giving me problems and I think I figured out why. Everytime I start using the internet, and connect to my wirelesss network, My pc would crash within 1-20 minutes. I did some research about wifi cards taking alot of energy so I unplugged my 6 USB devices except for my mouse. Then my pc would last longer, about 20-40 minutes. I decided to take it a step farther and take out my sound card, and unplug my DVD and Floppy drives. I also underclocked my CPU to 3.0 Ghz and now my pc will run for about 1-2 hours before crashing. What do you guys think?

Thanks,

Ify

Does it lock up, or does it completely shut down/reboot? What are your processor temps looking like? What PSU do you have now? your specs don't look like its very demanding for a decent power supply. Are there any unusual looking entries in the Event Viewer around the time of the crashes?
