Pc keeps rebooting

[offerz]

My pc keeps rebooting after 2 secs. And on for 2 secs till I unplug.
I've tried reaseating the ram use 1 stick blow slots use other sticks in other slot and also I tried the cmos jumper and it wouldn't even boot when I had the pin installed. I had it powered on and connected the jumpers on the motherboard. It stayed off until I let go. Also tried reaseating the cables. And connecting more Hdds and disk drives. Nothing worked. No pins bent and tried removing and replacing the cmos battery. No luck. I also have no paste under the cooler but when I turn on the pc and let it turn on a few times and remove the fan CPU is cold. Plugged in a keyboard and it lights up. I have a coolermaster 520w modular power supply. With. A led on the back. When I turn it on with cable Inserted the led doesnt turn on. When pc Is turning on it is blinking for about 0.1 sec and turning off while pc is on. Help me please

i had the same issue a while back and it ended up being the PSU. Sounds like you have a bad power supply

Could be. I just tried the "paperclip" trick and the psu is no longer powering on. I did get a video that the psu was spinning without stopping from the seller. Green+black on the same row and one pin is missing.......

 

[japps2]

yeah...you need a new PSU. should be able to get something for $60-$70

 

[offerz]

Thats a lot

 

[offerz]

Didn't do it. Bought a new one no success

 

[offerz]

Bought a 300w be quiet in box. Still same effect. Everything spins and so then just shuts down and restarts

 

[japps2]

check your power on connector and pins. other than that I would start looking at the motherboard. did you buy all the parts new?

 

[japps2]

also, check to make sure your CPU power is plugged in...the 4-pin plug at the top of your motherboard

 

[offerz]

All used. Psu new and all pins are not bent and CPU supported. 8pin connected

 

[japps2]

do you have access to a friend's PC to check parts on? I've had the issue you are describing twice...once it was the CPU cooler not being plugged in and therefore the fan not spinning up and cooling the CPU...it would thermal shut down the system after about 2 or 3 seconds because the CPU was overheating. the other time was a bad PSU. What type of CPU and motherboard?

 

[offerz]

H81m-s2ph
Intel stock and i3 4160 2x2 GB ddr3 10600u 09 11 a1 m378b5773dh0 by Samsung and cooler master paste

 

[offerz]

No one has 1150 socket

 

[japps2]

wait...I just re-read the original post...you don't have any thermal paste under the CPU cooler? that would do it...apply thermal paste and set you cooler up normal and see if that works

 

[offerz]

I applied it today when I installed new psu. No effect its cooler master e1

 

[japps2]

double check all you wires and cables. re-seat everything. make sure your reset SW isn't plugged on the power SW. troubleshooting guide: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems


hopefully it's not the motherboard...trying to find old hardware can be challenging.

Done that red whole quide. Nothing helped. Not psu maybe unsupported ram. Or dead main bios can't figure how to get into backup

 

[offerz]

I have decided to sell the worthless thing so I can buy an older 2th gen i3. Or buy an 1151 new board. I've bought 2 boards from gigabyte within an year and all ware dead when I got them. Though the sellers said they worked. One with an Pentium 1151 and now an 1150. I'm never buying gigabyte again instead I'll buy Asus or asrock.

 

[offerz]

I will close the thread. Thank you all for the comments but again nothing worked.

 

[japps2]
