So, having had trouble diagnosing my old pc, I replaced my shuttle sd37p2 with the sg41j4. I moved over the same cpu (core 2 duo e6600) and hd and video card radeon 3870, all stuff I got 5 years ago or so.

Anyways, I thought the psu was the issue with the old shuttle so I decided to get the new barebones seeing as how a new psu for the old one would cost the same. After getting a new 4gb ram stick, I put everything into the new one with a new intel cooler for the cpu and the new ram stick.

Still the same problem of no video on the screen (whether with video card or using on board video)

So, I have determined that the cpu must be the issue. So, looking to replace it, I had a question to ask.

Which cpu should I buy? The things I will be doing with this computer are:

internet browsing and video, watching video files (720 & 1080p), playing fallout new vegas and dota 2 (maybe heroes of newerth), mostly not that intensive games. I think the video card should handle everything fine. So, what is the cheapest cpu I can get to replace?

the cheapest ones I see are:

and

for $20

for $50

and

http://www.newegg.com/Product/Product.aspx?Item=N82E16819116392

for $80

What is the best to suit these needs? I am tempted to buy a cheap one for $20 and test it with the old shuttle system and if it works, just give the new one with the cheap cpu to my parents and buy a better cpu for myself but at this point, I am not even sure the cpu matters with my crappy video card.

What do you guys think I should do? Or is my cpu even bad haha

No beeps that I can hear.

I determined bad cpu since:

ram is new.
mobo is new.
psu is new.
cooler is new.
bad hd would not prevent video from showing.
both video card and on board (with video card removed) video did not show any video.
monitor works with laptop.
cables all work.
the only thing I can think of is bad cpu since it is the only same component in both old and new system

The computer turns on with all fans working and the HD spinning. I ordered new ram.

in reference to the wolfdale cpu, would the $20 cpus allow me to play fallout and dota 2 (prefer @ 1080p resolution low settings) with my radeon 3870? I also saw on newegg the e5700 and it is $6 difference for .06ghz. I'm not sure if that is significant for some reason I don't know that it is $6 more. Thanks

also, I didn't see the wolfdale cpus compatible with my old shuttle, but would it work if it is the same socket or not necessarily?

liangrome,

if this is the model you are having issues with:
http://www.shuttle.eu/products/mini-pc/sg41j4/overview/

then under the manufacturer's specs:
http://global.shuttle.com/products/productsSupportList?productId=1480
is the compatible CPU list some of the cpu's need a bios update which you can get there.

and there is alos a list there of comaptible graphics cards if your looking to upgrade there.

and wow i must apologize if my first comment was curt, i had no idea a small box could pack that type of punch.

I don't know about the old Shuttle, I just checked the compatibility list for the new one :)

The Pentium 4s will absolutely be too slow, plus they run hot. The Conroe is better than an AMD dual core from roughly the same era... not a strong CPU though by modern standards.

The Wolfdale I linked is not too far behind modern CPUs, and can probably do OK with most games, but not all. For your usage, with a Wolfdale CPU, the biggest bottleneck would be that old GPU.

If you had been asking before you began buying parts, I would have told you to upgrade to a more modern platform. You can make this one work for a while yet, though.

You should have got the one I linked.

Likely you got confused by something you read. There were TWO E6600s. One was old tech, the one I linked is newer.

Here are the two CPUs together. Note that the E6600 runs on a faster FSB... they say 1066 but that's marketing, they multiply by 4.
http://ark.intel.com/compare/42807,42802

E6600 = 266 bus
E5800 = 200 bus

Having said all that if you are overclocking it MIGHT be the better choice. Since it starts out with a lower FSB and a higher multiplier, any increase in the FSB will yield big gains If you could raise it as high as 233... but you have a G41 board and I have to think it doesn't OC much if any.

here is a shot in the dark, maybe your video card has a problem.
(that 3870 might be tired and sucking too much juice from the pci lane and straining that 250w PSU)

have you tried installing *just* the cpu and ram in either shuttle?

since you have more patience than i do; with having enough components for two shuttles, there might be a combination, that for whatever reason, works in either of the shuttles.

have you tried old shuttle, old cpu old ram w/o video card?
then old shuttle, old cpu, new ram . . .old shuttle, new cpu new ram . .old shuttle, new cpu, old ram.
then repeat with the new shuttle.

i have found through my own experiences that doing a voodoo dance doesn't hurt . . sometimes i think it helps. (along with a pot of coffee)

I actually did try those combinations. Keep in mind my old shuttle has a bad psu so I cannot test it. I did try the new shuttle without the gpu and nothing came up as well

is the power cord long enough that if you removed the motherboard from the old shuttle, set it on non conductive material beside the new one, such as cardboard, and plug it in to the psu of the new shuttle?

i am wondering that the old PSU went out on your old one and you received a bad motherboard in the new one.
