My friends family have a self built PC: i5-2500K not overclocked 16GB Corsair 1600Mhz RAM, Corsair 850TX power supply 2 by 2Terabyte & 1Tbyte Seagate hard drive - all 80% empty & fully defragged Win 7 64 ultimate fully updated Office 2007 fully updated Asus Nvida 550 GTX graphics Fractal design R3 case USB 3.0 Pioneer bdr 207 ebk & times 22 Samsung DVD writer Thermaltake Frio cpu cooler Asus sabertooth P67 motherboard It is running through a Belkin power surge protector. They have done a chkdsk & memory test via memcheck - no errors. The problem they are having is that when they press the power button the blue light around said button normally gets bright blue. But since last week the fans come on the power button flickers a light blue & the PC need switching on at least twice. They have checked CPU temperatures via core temp. It says 27-32 Celcius on all four cores. In the BIOS the computer is set to normal. They have done a virus scan via Norton, malwarebytes, superantispyware, spybot & emsisoft - all clear. The PC currently runs fine in Windows. What is causing my problem please? I have changed the power supply to a Corsair CX 750M.The same thing is happening. What else can I do? thanks to all the advice in advance. Thanks to all
Go to "Control Panel" > "Hardware and Sound" > "Power Options" > "Change what the Power button does" and see if the settings need to be changed.
agreed..sounds like it's going into sleep mode instead of powering off. The bios should have a setting for this
I am extremely grateful for your replies. I looked on the computer & it says : Power Options" > "Change what the Power button does" - it says "shut down" when I press the power button.
I have replaced the power supply. So what can be done about the motherboard? Will a bios flash to a newer version help? Since they have not flashed the motherboard bios (rev B3) since I built the machine.
Probably do no harm updating the bios and see if it does make a difference also check power plan (also advanced settings) not just what the power button does.
it could also be something as simple as a USB device holding up the system. Try unplugging all peripherals like external hard drives, printers etc. Just something to check before spending more on other parts
Hello all, I did what redroad asked of me. The computer at boot up needed a repair, this did not work & then a system restore. I could luckily still get into safe mode & back up all my documents to a physically separate internal hard drive. The computer & for now it is behaving. Also all I have plugged in is a usb 3.0 hub & my Samsung laser printer as well as a Microsoft mouse.
No, I do not think so. I left the machine off for a few hours as to see if it boots fine when starting from cold. It works now.
I am still posting from work - so I will be brief. I opened up the front of the case, lookes at the wirs & saw nothing broken. I re-inserted the wires at the motherborad & then tried again. No problem booting. That was last night & I will try again tonight.
Hello all, I have this that came with my motherboard: ASUS Q-Connector MAXIMUS IV EXTREME GENE-Z/GEN3 SABERTOOTH 55i 990FX P67 X58 I re inserted all the wires from the case & so far so good. Thanks for your help.
