Hi everyone. I am new at this, so be gentle. Anyway, I came home from work today and my computer was turned off. My roommate said that we had a power outage today. Well, I tried booting my computer, but it said that Windows was unsuccessful. Try starting Windows normally, in safe mode, etc. Anyway, I kept trying to boot normally, but I was not getting anywhere. I also started Windows from an earlier point. I did not get any beeps or anything when my computer started. After a couple of tries, my computer started Windows. I'm not sure if it is the PSU or the motherboard, or something else. Any help here is greatly appreciated. Thank you!
It could very well be either, but I've seen those exact symptoms on a lot of systems with bad capacitors on the MB. I'd open the case and take a look just to make sure you don't have any swollen caps or any fluid/dried crust on any of them, especially those closest to the CPU socket and voltage regulator.
If it does turn out that it's the PSU, make sure you get a good quality unit. The sub-$50 models are often more trouble than they're worth. Pretty much anything that you see reviewed on the hardware site should work.
