I have a Gateway lx6810-01 desktop. I started off having problems with random shut-downs - so bad that sometimes it wouldn't even complete booting before a shutdown (only sometimes was it that bad, not always , but I couldn't figure  out why it did this only sometimes).  I read that my particular model desktop is notorious for random shutdowns, so I purchased 2 case fans and 1 PCI sIot fan with hopes the added circulation would fix the problem. I installed the new  components, however when I started the system back up, all the fans came on but no beeps during startup and no display on the monitor.

 

My first thought was graphics card failure, so I swapped the card with a card from another computer I knew worked. That didn't fix anything, same problem. Next I thought somehow the motherboard failed. Replaced the mobo. This didn't remedy the new issue either. What else could cause the computer to not beep, but all fans come on, and no monitor display? Prior to adding  fans, I had a display. When I replaced he mobo, I didn't hook the new fans up just in case the fans had blown the previous mobo, so I  now ruled out the fans as the culprit. 

 

Help!

First thing to do is to check all of your connection from the PSU to the peripheral devices, you may have cause a connectivity problem.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Could be a lot of things - bad PSU, the RAM, graphics card, other PCI/PCIe cards that you might have installed, failed components on the mobo, badly seated CPU/failed CPU. 

I would reseat all the components first and blow some compressed air and try to reboot, then would start by removing all addon cards, minimum ram and see if improvement, if not then look at PSU first and go up the list of components starting from cheaper to more expensive.
