Re-Build Computer


Likes # 0

Evening, right I don't even know where to start ehehe but here it goes... In 2006 I built a computer which would last me at least 5 years, it's now almost 6 years, and poor little guy is struggling...

The thing is, I use to know quite a bit of computers hardware and software, but this was 6 years ago... recently I found out that manufacturers don't do any more parts to desktop... which lead me to a trip to the unknown...

I'm completely lost, Motherboards, drives, cables, everything is looking more and more from the twilight zone for me (yes I'm getting old too).

I know there's a budget for everything including build a PC from scratch like mine but since mine is quite old I just want to upgrade it so I think I wont need to spend a big amount of money (like £1000) since it might be easy to find some parts... I don't want it for gaming or so but mainly I need it touse AutoCAD (don't know if you recognise this software but involves 2D and 3D drafting, with lots of rendering)...

I would like to ask you guys that are definitely more experienced then I am, what Motherboard, Drives, etc would I need to get to achieve this. I'm not asking a top of the charts piece of hardware but more like near the bottom parts but better then what I've got.

Can you help me with this?

Modem? What modem? I hope you're not talking about internal dial up modem card :), if you mean broadband modem router then you should talk to your ISP, they should provide you one FREE nowadays.

ehehe I am talking about and internal dial up modem card eheheh I told you, my computer is well old eheheheh

Since BT hub connects directly to the computer so it's a wired connection I think I could give it a bit of upgrade but don't know what to go for...

Let me check your spec. give me a sec.

I am assuming that you have broadband? Which would mean a router which you would connect to your PC via an ethernet cable.

Richard - remember you posted this -"My budget goes between £250-£400"... you are drifting far from this, and you need to ponder long and hard if the expense is really giving you what you need. Sorry if that's being a killjoy. You are building a good system that will last, but it's far from your original budget!

Thanks for the reminder bjh... the main diference is the budget of £250-£400 was to build a computer as soon as possible this meaning a 1 motnhs or 2 weeks... I put in my head that I can go further in costs but it will take longer to build...at this moment I think it might take 4 to 5 months in total but I'll have a decent computer for some years...either way thanks for the warning...

Ignore my hard- drives as they are 2.5,laptop, you are looking for 3.5 desktop.

My mistake I am in the middle installing windows and messing about with the heating boiler and using the iPad,so chaos reins. I' ll be up and running shortly but *Retep888's * suggestions look good.

Forget about internal dial up modem card for Win7 64bit system, it hardly works.

If you mean you intended to upgrade your desktop to wireless then make sure your BT Home hub is one of the wireless version (if not then ask BT for one ,they should provide you one without charges), get one of these wireless PCI network cards as well. click here
