help mobo is humming

[thop]

In the meanwhile the 2nd IDE port completely failed.

I replaced the faulty capacitor, turned out there are actually two (next to each other). The second didn't make any noise, but it looked very suspicious.

Anyway, capacitors are replaced, i plug everything back in and turn the PSU on ... the bee is still there!! And it is the brand new capacitor that is making the noise. About a minute later the system powers on, 2nd IDE slot works. I turn it off/on again, and it's still making the noise.

Ok so i test the mobo with a cheapo 250W PSU, the noise is gone, system powers on immediately! I open my old Zalman 300 PSU and what do i see? 3 imploded capacitors, all with a brownish top.

It seems that the faulty PSU slowly degraded the capacitor until it got broken which is somehow related to the not working IDE slot. So MSI isn't to blame

I have experience the "faulty PSU kills capacitors" often enough to not be surpricec that the real fault was in the PSU

I found that sometimes the CPU fan will sometimes sound like a it's humming when it's going bad...you might try to swap that out and see if that fixes it...

Edit, upon reading the rest of the replys...


Never Mind...But good dective work!!

It seems that the mobo probably took some damage I replaced the capacitors again in the meanwhile because i thought maybe they took some damage during the few hours i had them running with the faulty PSU, and i hoped that fixes the problem i am about to describe

The problem is still the 2nd IDE Slot. On first Boot it will recognize my writer (Plextor PX-W 2410A), but as sth. like Pleptox PD-R 24R0ZA. A few letters are always scrambled. Needless to say it doesnt work in XP.

However when i let the computer run for about half an hour, and reboot, the writer gets recognized how it should be. Seems sth. needs to get "warm".

What might that be? Another faulty capacitor that doesnt reveal itself like the others? I wouldnt mind replacing more of them How do i find out which one though.
Any advice appreciated

If your PSU has gone, it's almost guaranteed that the MB took damage. If you bought the two parts from the same vendor, then you should get him to replace both.

same prob

hey thop i am having similar problems with the bios not detecting my IDE2 devides, but my mobo is a GA-6VX7... had the board for about 2 years now... and started happening about after 1.5 years... of course when the warranty ran out

but mine only happens about once a week... and I just have to hit the reset button and it boots fine detecting the IDE2 devices... so i didnt really worry that much...

but am hoping to get an upgrade soon... not sure what to get though... either the MSI sis max (665), or the GA-8INXP...

what do you guys recommend?

thanks
