I have an hp h8-1214 that i got from best buy. It supposedly has 300w psu, amd fx 6100, and an amd 7450.
I went to frys to get a new card, the amd 7750 because it was the best card for the current psu i have.
I installed it yesterday, the fans spin, however nothing is shown on my monitor. It goes into powersave mode as if nothing is connected to it at all.
Im beginning to think its my psu or the gpu is dead.
I cant test the gpu on any other computer and the pci slot isnt busted because my stock card (amd 7450) works fine when i put it back in.
Im fairly new to all of this upgrading stuff, any help is appreciated.

Hmmm... It actually could be your PSU.
I'd recommend this PSU:

Actually the Corsair builder series isnt all that great... It's about the same as the one I put up there.
Bottom line: upgrade your PSU because it is most likely your problem
Here are the two PSU's we recommended:
500w:

430w:

There was a coolmaster 500w for 50 bucks at frys. Should i try getting that and replacing the gpu with a 7770 since ill have more power? I kind of want the asus one as it seems smaller and the gigabyte is a behemoth..
If it is a psu issue, do my current symptoms check out? Like the fans spinning and pc coming on but no display whatsoever (Not even bios)

So i went and got a lepa 500w.Hooked it up, then realized the atx 12v connection on my board is 4 pins and the one on the psu is 6.
Is there a way around this?!
That might be a GPU connector (they are 6 (+2) pin). The 12v connectors should be 4+4, you only need to plug in one 4 pin head.

I only had a 6 pin and a 6+2 after i connected everything.
On the box it says it has a 24 pin main power, 4 pin peripheral, 6 pin pci-e, 6 pin + 2 pci-e, sata, 4 pin floppy, and a 4+4 pin CPU.
Im guessing the 4+4 pin is the one i need to use but i couldve sworn i only had the pci cables left once i hooked it up.
Also, the 4+4 is one solid piece. Its not broken in half. Do i have to split it myself?

I just opened my pc. I dont see a place where i couldve used that 8 pin. I must have over looked it once I panicked and thought that i needed to use a PCI-E cable there.
FML
So, i guess im going to put her down for another surgery and try this 4 pin.
I guess my next question would be, if this works, do I need to uninstall my previous gfx driviers? Also, will it be able to display through HDMI on boot with the new GPU or do I need to get a VGA cable?

Im gonna return everything back to frys and either get all diff branded stuff or order it from newegg. This has been an embarresment of hassle.
((Buy the CX430M it's modular and you only have to hook up:
Assuming you only have that card:
1. 24pin MOBO power connector
2. 4/8 pin CPU connector
3. GPU 6 pin connector
With that you will only need to plug in 3 cables to your power supply. That would be a good option.

Also - Another person suggested that I may need to go into the BIOS and set it to display through PCI-E.
This card didnt use the PCI-E cable from the PSU, so is it really a PCI-E card? Would I need to do this anyway or should windows default to it on its own?
Another suggestion Ive seen is that because the GPU is drawing power from the mobo, it may not be getting enough. They suggested to find a card that DOES use an external cable.
Does anyone know of a card similar to the 7750 or 7770 that uses the PCI-E cables?
