My windows 7 keeps restarting repeatedly. It started doing his around two day ago. I've resetted the computer twice since then and it keeps lagging. It takes forever to reset. It lags booting up ad everything. I don think it my hardware cause I've had this computer for around a year and I've never had this problem before.

Please provide your full system specifications, including the brand and model (not just wattage) of your PSU. Thanks.

How do I get to the windows logs? An I custom made the computer. I'm pretty sure it's not the hardware. It has been working.

Click start > search and type "view event logs".

Open event viewer by searching on the start menu for "Event Viewer", on the left hand side expand "Windows Logs", then click on "System" and look for any errors around the time & date that a restart occurred. If you see "Critical - Error ID 41.... Kernel - Power.... The system has rebooted without cleanly shutting down...." then I would bet it's an issue with your power supply. Especially if your PC has been working fine for a year and this only recently started occurring, chances are your PSU is going bad. If you don't see any Kernel - Power errors look in "Application" logs.

Can you list your system specs? Be sure to include your power supply in the list.

Have you tried the "repair" mode?

If there were no errors found, it looks like you might have power issues with the computer - either that or fans are not spinning creating heat issues. Both will cause the computer to restart. I would suggest removing the cover and observing the fans - make sure that all are spinning properly, and free from obstructions (dust is an obstruction - canned air can clean it up).

I've already dusted it out. Heat shouldn't be a problem... All six of my fans work perfectly.

So it powers on, makes it to a certain point in the boot process, then automatically restarts? Does it restart at the same exact point every time?

What do you mean by "resetted", did you reformat your HDD and reinstall windows? If not I would probably try that or else a new PSU... If you've got files on the PC that you're unable to get to in order to back them up before reformatting you might want to try a new power supply first, but that would mean spending money.

Can you list your system specs? Do you know what brand/model/wattage your power supply is?

It's not the PSU. I just replaced it this morning and it is still in the reboot loop.

The boot sector from the hdd may be corrupted, so every time it tries to load the needed file from there, it gets stuck and reboots. That's my best guess. Boot up HDD Regenerator and do a full scan for bad sectors. This is one of the possibilities. The other one would be to check the BIOS section called Hardware Monitor to see if you get high temperatures. If that's the case, consider cleaning up the fan, the radiator, the old thermal paste from the CPU, put there some new paste, put everything back in place, and go again in HM to see the new temps. You can also try to boot the system with only one bank of RAM (IF you have at least 2). If you only have one, try putting it into another slot. If none of these is the problem, i'll come back with other suggestions.

Aaaa...you think? :) )) It's reached 102 degrees man. Clean the fan, the heatsink, replace the thermal paste.

Having just realized that yellow-power ftw hijacked this thread belonging to Nicolas Cristy, I'm clearing all of that out, with apologies to Nicolas.
Yellow-power ftw, if necessary please begin a new thread of your own (as it appears your problem was resolved). Thank you.
