This is a running thread of mine that I started asking for help picking out a video card. Recieved the card and the machine isn't booting. Instead of typing everything all over again I figured I'd start a thread over here (since to me it has to do with BOTH pieces of hardware, not just one or the other.) and get input from here as well. Trying to get as much coverage as I can. Thanks for any help!

*Quick breakdown*

Computer normal boot(onboard video) = all fans at full speed(until into windows and speedfan takes over) and power light on the front of the case is on.

Computer with RAM removed = fans at full speed, power light on, post beep for no RAM.

Computer with 3.0 video card installed in 1.0a slot = no light on the front, all fans running at min. speed, no display.

Computer with 3.0 video card installed in 1.0a slot and RAM removed = no light on the front, fans all running at min. speed, no display, NO post beep.

Latest BIOS update is from 2007.

Sometimes incompatibilities like this happen and there's nothing you can really do but get a different card. Since the 260X worked some PCI-E 3.0 cards should work as well.

Try the GeForce GT 630 or 640 from Nvidia. PCPartPicker is great site for finding the cheapest possible prices.

*Added a little more info*

Card works in another pc.

Tried power supply from other pc (CX500, MORE than enough to handle R7 240 card).

Tried doing out of case hookup. Only thing connected was PSU, RAM, CPU, new video card.

Tried changing settings in bios from auto to PEG/PCI-E (not sure that would matter if pc isn't even getting to POST)

There's quite a bit of info in the original post, if you don't feel like reading everything or just have another questions then please ask and I'll give you as much as I know. Thanks!

*Edit*
I will go through this page more thoroughly today/tomorrow. However, doing a quick scan I'm 99.9% sure I've done everything on the page. *shrugs* Doesn't hurt to try one more time. Only insanity will prove if it does any good. :D

*sigh* I really should have expected this, but I just got e-mails from both ECS and DIAMOND. DIAMOND says the motherboard can't support/handle a 3.0 card and ECS says the card isn't compatible with a 1.0a slot. *bangs head on wall*

PSU is fine. I put an R7 260X into the machine (with dedicated power) and the machine booted right up. So I'm wondering does the board get blamed for not pushing enough power to the PCI-E slot? Or does the card get blamed for trying to pull too much power since it gets all of it's power from the board? (No dedicated power on this card).

Another twist to throw in is that at one point I forgot to plug the six-pin plug into the 260X but the machine still booted fine (just no display). *shrugs* I don't know enough about the engineering details side of things to know what's going on. So I'm assuming that I either pick out a 2.0 card or a 3.0 card that's on par with the R7 240 but with dedicated power? Or do I contact other makers of the R7 240 and see if they can guarantee that their card will work with 1.0a because of the power issue?

Yeah, I'll have to definitely do some thinking. I can't afford to buy a card at full price and then turn around right away and only get 50%-75% of the price back. Like with that R7 240 from Newegg, not only am I going to have to pay for shipping to send it back but also a 15% restocking fee. So I'm looking at losing $15-$20 on the card I just bought.

Well, I REALLY didn't want to go this route, but I think I'm just going to get a new/different board. I was trying to keep the money in this thing to a minimum. My wife made a good point though. If we're going to spend $50-$70 on another video card that may or may not work why not just get another motherboard? lol This will also allow me to put more ram in the pc. Now off to find an LGA775 MB. Thanks for all the help! Sorry I wasted your guys time with this video card issue.

Just to let everyone know, I figured out the problem. Well, actually it was figured out FOR me, but still. :D It's because the PCI-E slot on my board is a PCI-E Lite slot. Which means it will physically accept and run an x16 card, but only puts out the power for an X8 card. Which means it only puts out 25W of power. Someone over at overclock.net pointed it out last night.
