Computer constantly restarts --- works fine in safe mode.

Hello everyone,
I am back with more computer issues.

So yesterday. My room mate decided to run an Ethernet cable from our router upstairs and change our router location. (this I dont believe has much relevance to my issue, but explaining what happened yesterday). He said he only removed my Ethernet cable and did not touch anything else.

So as to my surprise yesterday, I turn my computer on... it loads normally but then my monitors begin to flash and turn off.
I have a 26" and a 22" one VGA, one HDMI running on a 2gb MSI gtx 770.
The monitors turned off for about 15 seconds, then I saw my desktop again, then it turned off and actually restarted.

It loaded, I thought maybe for some odd reason an auto update restarted it. When it signs back in, it begins happening again.
I assume a virus, or something screwy along those lines. So I boot to safe mode. I run MSE and malware byes...nothing.

I check the cables in the back, everything is in correct and tight. I browsed around and found nothing online giving me any idea what could be causing it.

Has anyone ever experienced this issue, or know what could be causing it? I cleaned my computer out recently, I dont think theres too much dust in there. Anything you would recommend, or where to star in determining the issue?

Thanks.

Sounds like you might have a hardware issue of some sort that started happening. When you cleaned out the system; did you remember to do it with the system off? If not; the blowing around of dust inside the case could have shorted something. Only reason i say this is because I mistakenly did that once and i heard a loud pop sound and suddenly my system shut off. Fortunately for me it didnt do any permanent damage. But back to this issue; I would check your power supply; as often when a computer suddenly reboots without reason it could very well be due to a partially faulty power supply that is starting to go bad; and or a possible motherboard issue. For the power supply i would try and get hold of a volt meter and test to make sure your power supply is still putting out proper voltage. However; if it is a motherboard issue; there is not much that can be done short of replacement as the mb is the heart of the system next to the cpu.

Hi thank you for the reply.
I cleaned my computer out about 2 weeks ago. Its been running fine since.
I was thinking power supply. When my old one had started to go, it would turn off completely. This just restarts and goes in a restarting loop.

Hello Brian,

Since it works fine in Safe Mode, you might see if troubleshooting with a clean startup may be able reveal a culprit. If so, then you could either disable it, or reinstall a newer version if a driver.

Thank you for the suggestion. I am definitely going to try this. I am goign to try anything. Hopefully this can help pinpoint the issue, and maybe a clean install could be a good fix. Hopefully I dont have to buy new hardware. Damn christmas season.

If not then test the hardware from the Troubleshooting Steps for Windows 7
then if hardware tests okay continue with the rest of the steps which often will uncover the problem.
