Help!storm damage

[diesel_dork22]

Well down here in Houston,Tx we recently had some storms from the hurricane on the coast and on the 3rd of this month had a thunderstorm that i think sent some surges when the lightning hit and made the power go off a couple times.I didn't turn off my computer.......big mistake.I then can't turn it on so i turn the ps off and unplug it and rehook it.Great it comes back on but i have no internet connection neither does the comp in the living room. I figured it knocked out the onboard lan so i got some network pci cards they work and that proved my point. My problem now is i have noticed slow down in performance and sometimes some random freezes. I was trying to boot windows from cd to install it and the system kept giving me hiccups and even froze on bio screen. I now got it installed for the meantime but i can't help but notice the loss in performance. I also notice the readings on the corsair hx520 i got are a lil off more than usuall,and i know the ratings are usually a few points off but i got the 5v rail at 4.75 volts and it usually hovered around like 4.95 something around there same with the rest of the power ratings. I think it might be the mobo giving off bad readings. This is my system below....

Mobo is -Biostar tf560
ram is- 2 gigs muskin
processor is - amd 3600x2
psu is -corsair hx520 i think it's fine no problems with stability with it.
graphics card is -7900gs

I have been thinking about upgrade for starcraft 2 and what not and my mobo i can tell has problems.I think the most logical upgrade would be mobo and processor. I am thinking the amd x2 5400 brisbane black edition and the same mobo i got before cus i really liked the biostar plus the price is great.You guys think that would be a good match?

I had the same problem happen to a friend. Lost sound card and lan...replaced both with cards and all was well, but OMFG the system was so slow. All I can think is some of the internal layers got some tracks damaged(but not destroyed) or it really put the hurtin on a few FET's or capacitors onboard. I'm guessing you're running on borrowed time. Do you have any place to try out all your components ?

Was the computer attached to a surge protector or an uninterruptible power supply (UPS)?

I'm asking because the power supply may have also been damaged -- which is likely, because the surges would have gone through the power supply first, and is significant since it powers everything else inside the case. The damage to the power supply may not be noticeable now, but if it's transferred to a new computer, it may die suddenly without any warning and/or cause some of your newer components to malfunction (if not die outright).

You may want to test the PSU separately -- with no other parts running on it -- using either a multimeter (best) or a PSU tester. Check the voltages to be sure that they are within their prescribed limits. (There are guides online to show you how to do this.)

tiraides: not so true. remember electricity takes the easiest path of resistance. in a psu you have inductors, caps, resistors, where as thru a rj-11 or rj-45 it's a straight shot. I definitely recommend scoring a psu tester none the less.

The PSU needs some minimal load on it, the no-load voltages may be off (change of a few volts on some rails is not uncommon) or the PSU does not turn on at all, not mentioning that you may need to input a logic-level voltage on the atx turn-on control wire to turn on the PSU.
