I bought a new computer one year ago, it's worked fine (Windows 7).
A few months ago, it started to not boot unless I removed my USB headphones connected to a USB hub, everything else worked fine.
Today I pressed the space bar by mistake while the computer was going to sleep (which I assume caused the problem), and it rebooted it said that it had lost all hibernation information:
and has been acting strangely ever since:
- when it boots, it brings up a different boot screen (Asus Express something). I have to remove all USB cables before it boots further
- the first time it booted, the date had been set back to January 1, 2002. So I fixed the date, rebooted and now it keeps the date fine.
- I also noticed in BIOS that the boot sequence was reset to "floppy disk" first so I switched that back to the DVD
- the computer used to be very quiet, but now the fan runs loudly.
- in general it seems as though the mother board / BIOS has been reset to factory values or something like that
- also, every time I choose sleep or shutdown, after two seconds it starts back up again.
Here is a screenshot from speedfan showing that my first two cores seem to be too hot, which may be the reason the fan is running so high and hence so loud (although actually 50C-60C degrees turns out to be quite normal, perhaps they are not overheating, I'm not sure what they were before this issue):
Fifteen minutes later the CPUs seem to getting hotter:
Here's the basic info about my computer hardware:
- Asus P5QL Pro Sockel 775 Intel P43 max. 8GB DDR2-1066 ATX
- Intel Core2 Quad Q9300 Sockel 775 2.5 GHz FSB 1333 MHz Boxed 2x3MB L2 Cach 95W Yorkfield
- 2x Team Group TVDD2048M800C5 2038MB (2GB) DIMM DDR2-800 / PC2-6400 CL5 184pin Non-ECC
- Arctic Cooling Freezer 7 Pro CPU-Cooler Socket 775
- BE Quiet System Power BQT S6-SYS-UA-450W Netzteil 450Watt
- BE Quiet SilentWings BQT-T9225-LF Case Fan 92mm 16 dBA 32.6 CFM 1800rpm
Can anyone diagnose what happened / is happening to my motherboard/computer, and how I can fix it?
@barlop (in comments), thanks for the suggestion, my CPU still seems to be clocked correctly:
@barlop (in comments), I couldn't find anything in my event viewer recorded around the time when I put it to sleep and had the hibernation problem (in application, system, security events) and under hardware events there is nothing:
