I've just built a budget gaming PC into my my old PC's case (Oh lordy did I have a surprise when I found new motherboards don't come with IDE slots...) So, after getting up to speed with computer building since the last one I did was 8 years ago, I bought all the parts and put it all together, turned it on and.. The CPU fan span for a second then died. So I took it all apart, took the mobo out of the case and ran it just PSU and mobo (and CPU and memory, of course) and it ran fine. Put it all back in the case, ran fine, hooked it up to the monitor, all good, keyboard, runs good, and then I plugged my HDD back in, UH-OH, back to the brief start before dying.
So, I'm about to try GPU in with no HDD attached, to find out if this is an underpowered PSU issue or if it's the HDD being a giant turd. In the mean time, has anyone ever come across a HDD that could cause such a problem? It's connected to the mobo via sata, but it's only when the power supply is plugged in to it that it happens.
Also here's the comp specs
Intel G840 2.8Ghz Dual-core
8GB Kingston Hyper Blu
MSI GT 620
Ace 500W PSU
The HDD is a 250 GB Maxtor. I did some number crunching and used a website (Thermaltake, I think it was called) and it reckoned my computer would only run at 220W of power so a 500W should be sufficient, it is only a low power computer after all.
EDIT: It work absolutely fine with the GPU inserted, however doesn't go to the BIOS. I imagine this is because it's using the GPU as it's default port so that is a problem I will have to solve further down the line. So what's causing the failure, my HDD or PSU? The Psu seems to be handling everything fine until I plug the HDD in and then it just fails.
I think the HDD is SATA 1, whereas my mobo only has SATA 2 and 3 ports. But I thought like USB they would work backwards?
