Chumpesque

My pump seems to have stopped working. I've tried:

• turning it off and on
• manually spinning the impeller via the screw on the front
• giving it a light tap with a hammer

but it hasn't come back to life.

By the looks of it, this is a Grundfos UPM3 Auto L, 15-70 130 ZZZ.

In looking for replacements in the UK, I've found many very similar models but not the exact model. I assume there is some leeway in changing out the pump, but wanted to check beforehand: are there any issues in buying a similar model from the same manufacturer which I should be aware of?

Many thanks in advance and apologies if any of this doesn't make sense.

I built my PC a couple days ago before my GPU had arrived, and everything worked fine, I installed Windows etc.

Today, I installed my GPU and it seems like my mobo can't see the GPU. On the GPU, the fans spin, lights come on etc, but the DVI ports aren't working. When I plug my monitor back into the Mobo DVI port everything works again but obviously it is just not using the graphics card.

Do you have any ideas what could be causing this?

Thanks.

If it helps, Mobo is Asus Z97 Pro, GPU is Gigabyte 970

Edit: I've fixed it, please disregard. Edit2: Just realised I did that terrible thing of not explaining what I fixed! In case anyone else ever has this issue and Googling brings them here,

• This machine will be used primarily for gaming
• My budget is fairly loose - I'm happy to spend a bit more for a substantial performance boost.
• In terms of the case, I don't care about the appearance, LEDs etc. All I want is several USB 3 ports on the front (which I assume is standard?). Am I overspending here?
• I probably won't be buying this at the same time, but can anyone recommend a mechanical keyboard?

Thanks for the help!

So I've just finished my first build and powered it up. All the fans appear to be spinning, some LEDs come on but my monitor doesn't recognise that it is connected to anything.

By build was:

• Corsair TX 650W PSU
• ASROCK 870 extreme3 mobo
• G.Skill 4GB RAM (2x2GB)
• Samsung F3 1TB HD
• Antec 300 case
• GTX 460 1GB GPU
• AMD Phenom II Processor

I know the monitor works fine, so do you have any ideas or help for this problem? Thanks Reddit =)

Thanks Reddit - it appears one of my sticks of RAM is faulty .

First of all, I have never built a PC before, so I fully expect to have made mistakes through simple misunderstandings, so feel free to berate me for such mistakes =)

Right, on to the matter at hand. I'm looking to build a gaming PC for roughly £550 (so far I'm a bit over and am slightly further flexible here if it is for disproportionate performance increases) to play games like Starcraft II at fairly high graphical settings. The only other intensive use this PC will get will probably be a small amount of video processing, but this is by no means the priority.

My basic build is modelled off the one for a $700 gaming pc here, and

Even if you don't have your key yet, you can at least install the game now; if you have your key already, enjoy!

No balance changes by the looks of things and it seems we can keep our friends from beta - I really like that Bliz thought of that.
