the mobo has 4 high switching frequency buck regulators near the center of the board behind the io backpanel. this isnt recommended because it affects the esr of the circuit. is that another kzg or kzj cap? those are no good and are replace on sight even if they arent bulging and still look good.Īs for the mobo caps, u seem to have used replacement caps that are wrongly sized and wrong esr/ripple specs, so they wont fit through the through-hole of the board and they end up having to be left hanging up above the board. There is also a red brown cap with a Y vent near the dimm slots. the power supply could be bad and/or developed bad caps causing issues on the board. Is there someone who happens to own one of these Precisions and had this same exact problem? Do you think it is related to the caps? Should I try replacing them again?Ĭheck the power supply. The circled capacitors are those which have been replaced. I've snapped a few pictures of the motherboard. I am also suspecting the ones we bought to replace the old ones with are of bad quality. I once had a motherboard with capacitors that were barely buldging (they weren't even leaking) but still caused problems. All of the caps *seem* to be fine, but I've noticed that in these motherboards, the crappy capacitors tend to dry up after a while, ultimately causing issues, even if they're not buldging. I am unsure whether these errors are related to the capacitors.
Message 2: Alert! Error initializing PCI Express slot 2 (this explains why I wasn't getting video with the PCIe video cards). Message 1: Alert! Error initializing PCI Express NIC bridge.
I got an old PCI graphics card and actually got video signal but was greeted with two wonderful messages. So I figured if the computer is beeping, it's at least POSTing. I've tried multiple PCIe graphics cards and none worked. I decided to turn the computer on again and guess what, it beeps twice but there's no video. After a week or so, I turned it off and put it in storage. I even remember playing some old games on it without any problems.

As soon as I got it, we replaced its capacitors and I remember installing Windows XP and running Dell diagnostics. The problem was, like with most old Dells, the motherboard capacitors. These days, it’s practically impossible for anyone in the IT business to arrive at an unconsidered price for their product, so with NAS devices I’m not at all surprised to discover that the cost of putting together a simple Windows-based storage server is around 20% more than the cost of a mid-range NAS box.Around two years ago, I was given a Dell Precision 490 that wouldn't turn on.
Sure, this is without any useful drives but, remembering that Qnap review, most NAS boxes don’t come with drives either and NAS prices can be quite a shock, with six- and seven-drive units costing well over £1,000 (the Qnap box lists at more than £600 including VAT).

When I bought mine it was a bargain: motherboard SATA RAID, a dual-core full 64-bit Opteron at 1.8GHz, and four 3.5in non-hot-swap drive slots for less than £200 in the dealer channel. The machine I used for my Windows-based testing is an ML115, which is pretty much HP’s bottom-end server. So here’s the punchline and the basic reason I want someone to lay down the law a bit more transparently in the NAS marketplace.
