Hi guys, I can't find the section about PC stuff anymore so I don't really know where to post this. If this is the wrong section then please forgive me, I'm a bit out of touch with the site lately.. Anyway.. So, I have some problems with a few PC's.. The PC that I have an S2 tuner card in, it's working ok I guess. BUT, it's ancient, in PC terms. My ex built this machine for me several years ago. He installed windows 7 on it and then he put that app, My Theater 4. It appears to be written by some guy in Russia, as best as I can tell. My ex, the idiot, registered the app to himself, in his name. I hounded him for 2-3 years to change it over to me. He never did. Now his name is stuck on the screen. That's annoying but it isn't a show stopper. What IS a show stopper is that the Russian guy seems to have vanished and the app seems to be "abandonware" now. It seems that there are no more updates to it to support new things. I'm stuck using this app, some of you who have been around awhile might remember a few years ago when I tried EVERY satellite app known to exist and ~none of them~ would deal with the unusual switch setup I have. Overall, it's not that bad of an app, I just hate that it's stuck in time and they no longer support it. So anyway, here's where my real problem is. My other computer died. It was a home made Hackintosh. I have replaced it with a totally new, ultra wicked Mac Pro. What I want to do now is take the CPU from the dead Hackintosh which is an intel Core 2 Duo quad core and swap it into the satellite PC which is running a Core 2 Duo dual core CPU. They are both LGA775 and I know that they are interchangeable. The motherboards are, Gigabyte GA-X48T-DQ6 (the dead Hackntosh) - has the quad core CPU and Gigabyte GA-P35-DS3L (the satellite PC running My Theater 4) - has the dual core CPU But what I'm worried about is that I have read that the Home Theater app is locked to THIS computer. If I swap the CPU's out will the app stop working? How can I fix the app to not notice the CPU being changed? Or is the app locked to that machine forever? Since the app writer has vanished I assume that eventually something major will fail on the PC that I will have to replace and then it's game over for that app.. Yes no? Another question I have that's related to this, I want to build a file server out of the dead machine. Sometimes it will start but only gets to the initial Gigabyte logo screen then freezes dead. Most of the time it won't even do that much. I removed the battery from the mother board and shorted out the pins for it's setup memory for like three weeks. I think it's toast. But I have money invested in it. Last year I put 8gigs of memory in it. And there's the quad core. Turns out, they don't make or sell LGA775 stuff anymore. I checked on ebay for a replacement board and they are just way to expensive for a USED board. I need to find some sort of replacement LGA775 motherboard that has a lot of SATA connectors on it because I want to plug in a lot of old hard drives. I have a BIG case and a BIG power supply for it so there is no problem with putting 10 or 12 drives in it if I want. I need to find a motherboard that's compatible with the CPU and the memory sticks I have so I don't have to buy new memory and a new CPU. I want to spend as little as possible. I'm hoping to find a motherboard that's under $50 that I can pop my memory sticks and CPU in. MAYBE someone has an old LGA775 motherboard that will work with my memory and CPU that we could trade for some satellite stuff. I have a little collection nowdays.. TL;DR Can I swap a dual core CPU for a quad core CPU without My Theater 4 having a stroke? Thanks!
