So I bought myself a new video card and 400W power supply for it. Right away I had problems because the computer now makes a slight electric high pitched sound, which doesn't sound right at all. So after re doing all the wires for the power supply and what not, I try to start my computer back up. After taking way longer than it should my computer gets to my desktop, but everything seems to be missing. Programs like Steam, iTunes and uTorrent are all missing files that make them run properly. My computer can no longer detect wifi connections with the program I use either. What the hell is going on here? How can restarting your computer wipe out data like that?
post your specs?
The high-pitched noise can be coil whine from your GPU, and I really doubt replacing a PSU will cause Windows to screw up
Perhaps your hard drive was damaged somehow? Did you properly discharge the capacitors in your old PSU before removing it? Did you also check the HD was not damaged by the new PSU somehow (I doubt that would happen)
Very strange.

Why on earth would capacitor charge on an old PSU have anything to do with his current problems, let alone any problem.
The high pitched whine isn't something to be concerned about, it's just an irritation. The sound is caused by the inductor coils inside the PSU resonating. It usually only occurs on lower end and rotgut cheap PSUs. You can fix the problem yourself by opening up the PSU and putting a small string of epoxy across the coils to stop them from vibrating, though it would be better to just take it back to where you bought it and tell them it's defective (though it really isn't.)
As for your data loss, I really don't know what the cause of that is. I've never seen or heard of data loss occurring after the replacement of a PSU.
I've got the computer back to normal(ish). Got all my data back with a couple CMD settings. The only problem now is my computer is constantly shutting off randomly on me. Sometimes it'll be 30 minutes after restarting it and sometimes it's off again before it fully restarts. Anyone got the solution?

Disconnect components that aren't in use(cd drives, etc) to save power. You're demanding too much load from your PSU.
I think its my GPU getting too hot and shutting the computer down to save it.
I somehow doubt that, but again post your specs and we'll see
also temps would be nice

When I say old I mean the one he was previously using. You do know when you unplug your computer, the PSU will remain charged in its capacitors. There is enough there to kill you, let alone damage a fragile component. So, don't be so quick to rate boxes

You're saying when you unplug a computer, the PSU likes to send off discharges randomly to break components in a pissy state because it knows it's going to be replaced? I've never heard of that.

No, but pulling out the HD while the capacitors of the PSU are still charged is similar to pulling out the HD while the PSU is on, you know its not good.

Refer to this thread because I don't want to repeat myself:

In short, you have no idea what you're talking about.

Again, you have no idea what you're talking about. I think you think capacitors == batteries, which is completely wrong.

OH MY GOD, THEY'RE BECOMING SENTIENT!
As for your problem, the aforementioned PSU overload may be the culprit, but I don't quite understand it since the GT220 apparently only needs a 300W PSU.

Capacitors are not the same as batteries. In fact, they are breaks in the circuit. They are two plates which store charge, separated by an insulating layer. When charged, they can store charge for different times, depending on the atmosphere. Since the case of the PC acts as a Faraday cage, the charge is held on the capacitors for a longer time since the charge cannot 'leak away' as quickly.
When discharged, they perform the same as the [b]voltage which was supplied to them[/b], since the potential different between the plates was increased to the charging voltage.
So no, capacitors are not like batteries, these capacitors are nearly fucking [b]mains voltage[/b] supplies.
Admittedly, the capacitors only last a while, and yes not all the capacitors are charged to mains voltage (because the PSU has a transformer), but they can still make a kick large enough to damage a component.
Did I really have to prove I know what i'm blabbing on about here? :v:

the point is that they don't discharge for no reason whenever you begin to unplug a component and ruin that component
at least, not that I know of

No its not likely. But have you ever removed a power supply cable from the computer while its on (not the computer)? Or if you have old light switches, you can sometimes see a spark when you turn it on (or off)
These sparks can cause pulses of current larger than expected. This is why the RCD (or even a fuse) in a house may trip from time to time for no apparent reason (also if a light bulb blows but thats slightly different)
If this were to happen so close to the HD with no protection, that is why it could get damaged.
