My PC keeps restarting every 4 seconds

generalcardinal · Feb 25, 2015

My desktop Pc that I have had for about 3 years had been switching itself off every now and again for the last couple of months but for the last few days whenever I try to switch my PC on it just restarts/ reboots itself after about 4 seconds over and over again. I have tried putting a different PSU into it and made sure all the cables were properly attached. I regulary run all kinds of scans for malware and Trojans. Tomorrow I plan to see if my CPU needs more thermal paste applied to it. Please advise.

Try with reapplying thermal paste first then,

If the problem persist try removing one stick of ram if you have more than one in the memory slot,

If still unsuccessful, remove the hard drive then try to boot up

Re-applying the thermal paste made no difference and I tried booting up with all my hard drives unattached, both of which failed to make any headway. I have 4 sticks of RAM, what is the next step?. Thanks.

Well I have tried to take out each of my RAM sticks 1 at a time and still the PC only stays on for a few seconds. So its not:-

RAM
Thermal paste on CPU
PSU
Hard Drives.

Please advise.

Try a paper clip test on the power supply

Thanks for the reply. I did the paper clip test and the fan was spinning on the PSU. The guide mentioned it could be the power button or I need to clear the CMOS and I have done these and the same keeps happening...

If you can, Try with a different psu

Since you have 4 sticks of ram, there's little chance that all can be broken at the same time

If the problem persist even with a different psu then, its a broken

Cpu
