PSU went bang, now nothing...

Hi

I was putting together a new C2D system, new cpu and motherboard. I plugged in my old faithful Antec truepower and it went bang.

Now I've tried the system again with two other PSUs, and all I get is the cpu fan spinning and the HD light is on. I get no beep codes or anything. When I take out the ram, its the same - cpu fan still spins.

I dont have another intel board to test the cpu with, so I'm asking, when PSUs go bang, do they generally just take the motherboard out, or will the cpu have gone phut too?

I'll take the thing to work monday, try and find a intel machine there that might take the C2D, although I dont think our latest presler Dells PCs support it.

Do you think I should just RMA both the board & cpu and let them decide which is faulty? (it wasnt from ocuk)

Usually when I have dealth with dead PSUs, it is just the motherboard it has taken with it. Occasionly it can damage the CPU, but I don't see that anywhere near as often. If you send the CPU back as well and it turns out it is ok, won't the company charge you for testing it?

do this, if nothing then your motherboard may be fried, though in cases of overvoltage and/or PSU issues that broke a motherboard none I have dealt with have ever booted at all, i've had a PSU go bang before and the mobo was fine. Scared the crap out of me though.

I reset the bios, even took the battery out for 20 mins.

I think the way it acts the same, even if the memory is in or out is probably the proof.

I've had a faulty cold cathod invertor go bang and take an Antec TrueBlue out. After about 4 hours of pieces all over the floor and trying loads of combinations of PSUs and parts, I'd either get nothing, or just the fans spinning. Then it just came back to life. PSU, mobo, CPU and RAM still working to this day (the invertor which produced rather a lot of smoke was definately dead though).
