tanveer 59 Report post Posted May 28, 2012 (edited) I have a dual boot windows 7 and ubuntu PC. Since last 2-3 days, it reboots on its own and I see the screen attached. If I press f2, I can boot into any of the systems but then the system reboots again. What can be the problem and possible solutions? I hope my hard disk is not failing. I am tired of corrupt hard disks Specs of my desktop intel Core 2 duo 2.4ghz processor 4 GB DDR 2 ram Asus motherborad Edited May 28, 2012 by tanveer Share this post Link to post Share on other sites
Genius 817 Report post Posted May 28, 2012 There is nothing that we can tell by your screen shot ... It's normal I think the problem lies in your PC CPU fan or SMPS fan - or your system is getting heated by other means. Needs Chilling Share this post Link to post Share on other sites

prafull4u 24 Report post Posted May 28, 2012 Tanveer just check the cpu and motherboard Temperature while the machine is up and running, once i faced similar issue due to faulty Processor fan and the CPU temperature was going too High. And does that F1 F2 option comes every time you boot your machine.. I will suggest you clean the CPU unit and check if the problem still persist.. Share this post Link to post Share on other sites

Will check the temperature. About that F1 F2 thing, I know it appears on every boot. But only for a split second. And then it automatically goes to boot menu.

viper_in_blood 4 Report post Posted May 28, 2012 reload the windows os if the problem is cropping up too much.....os gets corrupred sometimes... Share this post Link to post Share on other sites
tanveer 59 Report post Posted May 29, 2012 I get the problem with both OS. So I think it is hardware related only Share this post Link to post Share on other sites
ami1 237 Report post Posted May 29, 2012 (edited) BIOS is not reporting any problem - its only saying it couldn't load saved settings. This happens either on hardware change OR because BIOS CMOS battery is down so it can no longer keep BIOS settings saved and loads defaults every time. There's nothing wrong with any hardware or OS or windows/linux Bootloaders Do the following:- 1. Press F1 to go into BIOS and then select option to "Save and Exit". Then reboot. 2. If you still get the same message try removing your USB mouse and rebooting and do F1 >> Save again once. 3. If you still get the message then replace your BIOS CMOS battery There's no issue if you keep using the PC with F2 load defaults every time till you get time to replace cmos battery. Its not critical. Edited May 29, 2012 by ami1 Share this post Link to post Share on other sites

Sent from my MB525 using Tapatalk cmos battery costs 20-100 bucks at the max. but did you try getting into safe mode of windows. does it still boot up. at least that will confirm whether ur windows is faulty. cos if it still does its definitely hardware issue. how is ur ram distributed. if you have empty slots then pls change ram from existing slots. sometimes there something that deposits over time and makes it difficult for system to read ram and it goes into boot cycle.

prafull4u 24 Report post Posted May 29, 2012 Tanveer you still didn't told abt your CPU temp while usage.. try speedfan to check the temperature. And CMOS battery will never cause the OS to reboot and the change is only required if you are getting that F! & F2 page every time you boot the machine and it should never cost more than 25/- rupees Share this post Link to post Share on other sites
Honest 836 Report post Posted May 29, 2012 Tanveer Ji, its seems to be faulty RAM. In your PC, if you have 2 dimms installed then try removing 1 and check whether your problem get solved or not. Share this post Link to post Share on other sites
thilak.kmb 19 Report post Posted May 30, 2012 Since it is a dual boot there should be a grub. It may be that there is some problem with the grub. I think you can go for a new grub. Share this post Link to post Share on other sites
ami1 237 Report post Posted May 30, 2012 Sorry, I didn't read the rebooting issue. I thought you are worried about the F1 F2 problem only. Please ignore earlier post. Boot with a ubuntu livecd (or any other linux live cd or live usb) and see if LiveCD OS also reboots after running for some time. If it doesn't, then it should be HDD problem. If it does, then its probably RAM or CPU. Or maybe a loose connection in your power supply or power switch etc. You can also run 'memory check' option on boot menu of ubuntu livecd or any other livecd. This option should also be there in most BIOS. If its not HDD or RAM then check cpu temp. Usually if an OS stops due to critical hardware error (like hard disk etc) then windows will give a blue screen with error num and linux will give a kernel panic screen with details. If these don't come up then it could be power supply issue or sudden errors in CPU or RAM. See if windows error logs last event gives you anything. Share this post Link to post Share on other sites
tanveer 59 Report post Posted June 6, 2012 I tried to disconnect the mouse. Did not work. I checked the cpu temp. Attached SS Please opine Share this post Link to post Share on other sites
ami1 237 Report post Posted June 7, 2012 Run the memory check in BIOS. If its OK then Boot with a livecd and see if it still reboots. See if you have a disk check option in bios, if its there you can use that instead of livecd. These 2 things should tell you about any memory / hard disk problems.

Jignesh_patel6744 7 Report post Posted June 7, 2012 Mostly it seems to be a memory problem...it normally behaves like that incase of memory prob....may be remove memory, clean it properly and re-plug it. Share this post Link to post Share on other sites
