Hi!
So I installed a new gpu yesterday, and on a first run it run fine, Nvidia experience said that the drivers are up to date too. When I rebooted my PC I got no signal on my monitors, So I tried to take off the CMOS for a few seconds and place it back, no That I did that the PC keeps turning on and off and monitors still say no signal. Also Looking through tthe fan I can see lights on my mother board and my keyboard lights up too, so I doubt that Momo is dead.
Anything I could do?

Thanks!

Whenever you remove the CMOS battery you should leave it out for at least 30 seconds to ensure the CMOS settings get cleared. While you're waiting to reinstall the CMOS battery, re-seat the GPU. Also, check the 6/8 pin power connections on the GPU AND on the Power Supply. Ensure that your monitors are connected to the GPU and not the MOBO.

If you have another open PCI lane, try moving the card to another PCI slot.

Additionally, sometimes monitors do not auto-detect input. You may have to set where they are looking for signal... For instance, if one is connected to the GPU by HDMI, set that monitor's input to HDMI. If the other is connected to the GPU via DVI, set the monitor input to DVI.

From my previous post....

IS theree any possibility of PSU failure, when I restarted the computer? Or perharps a driver confllict or something? And is there a explanation of PC turning on and off for only 2 seconds and repeating that process?

This is commonly referred to as a 'boot loop'. I've experienced this a few times myself and fixed it by removing the CMOS battery for a few minutes.

Please post the model/brand name of the following components: motherboard, GPU, and power supply so I can look into it further.

Here is another thing to try, to eliminate the PSU as the culprit.

If you have a spare (known to be working) power supply.... you don't need to remove the Chieftec psu from the case, just disconnect the leads to the motherboard (20+4) and replace that connection with the known-good power supply. If the computer stays on (doesn't go into an infinite reboot loop), you know it's the power supply that failed. If it continues to boot loop, you will want to either contact MSI (mobo manufacturer) to either troubleshoot or start the RMA process on your motherboard.

If you don't have a spare PSU, no problem. Perhaps just verify the 20+4 pin connector is seated correctly. Unplug it, and reseat it. You may have bumped it during the installation of the new GPU.

My own personal experience with PC repair shops... they are terribly unqualified. I hope they're better in your area. Best wishes.

I'm having the same problem with a gpu. It's very frustrating and very hard to diagnose at this point as there are no error messages to indicate what may be going wrong.
