Windows 7 - Continuous post beeping after PSU replacement

So first I had this problem which I think I may have solved. Windows will not load into or beyond login

Now I have replaced the video card with this one. Newegg.com - SAPPHIRE 100292DDR3L Radeon HD 5450 1GB 64-bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready Video Card

After replacing the video card the computer was non-responsive, after testing the PSU I found out it had gone bad. I found it weird that it blew up at the same time I replaced the video card. I did take the proper precautions with an anti-static wrist band while doing both jobs.

This is what I replaced the original PSU with. Newegg.com - Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply

Now with all of this having been done when I try to start the computer I get 17 post beeps. I have tried to search Google and my documentation for an explanation of the beeps with no luck. I don't know what to do now, everything has been plugged back in exactly as it was before. Any help is appreciated.

do you still have the old video card ? if so try replacing it and let us no what happens.

The old video card is fried, I'm concerned If I put it back in the computer I'll end up starting this process all over again.

found this link with beep code error numbers maybe it will help you.

That is actually one of the the search results from Google, but having looked through it there isn't anything that has an answer for 17 beeps. Also I am not sure of my BOIS version.

so it's 17 beeps in a row ? are you shore it's not more then 1 error being beeped out ?


scrooge

can you take out the video card and boot and let us no how many beeps it gives with the card out.
also do you have another computer you can test the video card on?

Your motherboard manual states

The following Award BIOS beep code descriptions may help you identify possible computer problems.
(For reference only.)
1 short: System boots successfully
2 short: CMOS setting error
1 long, 1 short: Memory or motherboard error
1 long, 2 short: Monitor or graphics card error
1 long, 3 short: Keyboard error
1 long, 9 short: BIOS ROM error
Continuous long beeps: Graphics card not inserted properly
Continuous short beeps: Power error

So long or short beeps?
Long beeps, try taking the graphics card out and use the onboard graphics.
When you replaced the power supply you did plug in the 8pin 12V connector?

If it is short continuous beeps then it sounds like you do not have the power supply connections installed correctly. The Gigabyte motherboard has a 24 pin main power connector and the Rosewill has a 20+4 connector. Be sure that both the 20 pin connector and that green 4 pin connector are plugged in and that the orientation is correct.
Most times the connectors will only go in orientated one way but we have seen one too many times the situation where someone has forced it in wrong.

Be sure the 8 pin 12v connector is plugged in next to the CPU.

Yep 17 short beeps. I've let it run the cycle 4 times before I shut it down.

I just took the video card out I tried to start it up again. Same results, 17 beeps, unfortunately I do not have another computer to try this on all of the other computers in the house are notebooks.

You Sir are a god, Where did you find those I poured through that book and found nothing on those codes + rep for you!

All plugs are installed correctly the 20+4 and the 4 pin up near the I/O plate. I've tried with both the 4 and 8 pin connector, the first PSU I used only had a 4 available. I'm not sure if that is the Northbridge or the South. There is only one difference with this PSU VS the previous The -5 V pin number 20 has been omitted. I compared them side by side and confirmed all colors and voltages. This is from my Rosewill manual "-5V is a legacy output and has been removed from all power distribution requirement since version 1.2. Only some M/B dated 1993 or older use -5Vfor ISA slot."

Thank you all for your help. I am really just lost on what to do now.
