Emachine T6520 Wont Start Up

Yes as long as your T6520 comes with at least a 400 watt power supply. It has the required 16x PCI Express slot.

Hi, you are having a problem with your add on cards, try to pull out everything that you have add on to you PC, then try to put 1 by 1 and try to turn on. If it beep once its OK, but if it's continue then the add on cards are the defective.

Hello
Try reseating the video card in the pci slot,remove completly then reinstall.

Also check your monitor video cable for being tight.

Last..Does this card require 24 volts? check for a 4 pin adaptor plug on the card.It may need its own power.

it should be printed on the motherboard itself. if not, go google emachine t6520 front panel connections.

You really aren't giving much info, so here are some beep - codes, also make sure nothing came loose on the motherboard or other components ( do this ONLY if you know how ) Safety first.

Switching DDR cards solved the problem. I was getting long beeps every 2 seconds. No short beeps. Just one long beep every 2 seconds. Thanks Josh Whitehead.

You have to reinstall the operating system

Based on your previous troubleshooting, with both built-in video and alternate video card, I'd guess you have a bad mobo. Anything else that was wrong with it (RAM, CPU, etc) and you'd get beep codes.

Sounds like it's time for a replacement board. If the eMachine is out of warranty, it might make more sense just to go ahead and upgrade now, as they are so inexpensive. If you are capable of replacing the board yourself, that would be the cheaper alternative.

Hope this helps - remember to rate (and great troubleshooting, btw!)

Make sure your monitor is plugged in and try again
