|Long story short i think my CPU may be dying.|
The problem is is that there are so many odd ball factors to consider that it could be any one of the components or programs on my computer causing it to fail.
Intel Q6600 @ 2.93, v3.75, Custom Air Cooling, Temperature: 33-45 degrees.
8800gt Custom fan non-overclocked.
Asus P5KC Motherboard (Intel P35 Chipset) Non-overclocked.
Creative PCI soundcard, PCI-E Wireless Card
I have had my pc for about 3 years now. One year after i bought it i thought i would give it a bit of a spring clean. I added a new soundcard, wireless adaptor, New Fans for the cpu and gpu, updated all the bios and attempted to overclock the cpu (the standard cooling on the 8800 gt was terrible)
When installing the new cpu fan i needed to take the motherboard out of its case. in doing this i managed to fry the onboard network adaptor and disk drive input (i have forgotten the name of it but i replaced my disk drive with a sata one to solve the problem) as far as i know only these two parts of the motherboad were damaged as i have had no further problems with my pc untill now (2 years).
I managed initially to overclock the cpu to 3.2 changing the volts to 3.75 to maintain stability with temperateures varying from 45-53 degrees. Over the following few months i slowly stepped down the overclock at the sign of any issues as a safety measure. reaching my final speed of 2.93 that i have stayed at untill now with no problems. The need to step down may have been ram related, i attempted to under/overclock my ram at some point in time but decided to leave it on auto for the sake of ease and step the cpu down to scale. When stepping down the overclock i forgot to lower the voltage, which may or may not have been causing the CPU to degrade faster than usual.
One final hardware Factor may be my PSU. This may just be a reflection on its build quality, but whenever i turn on my computer the psu fan bashes against its own casing for about 3 minutes untill it heats up and the bashing stops. THe fan still spins but just makes a horrible noise.
It may also be useful to note that for about 4 months prior i have neglected to run any anti-virus or anti-spyware scans, but having only had one case of a virus being found on my pc for the 3 years i have had it it seems unlikely to be a problem. The active antivirus software has been running, i just havent ran any scans recently. I use AVG and AD-Aware anti spyware.
about 4 weeks ago after restarting my pc it claimed that one of my disk drives was corrupt and it needed to run checkdisk. I ran checkdisk and it them worked fine with no apparent loss in data.
About 3 days ago i shut down my PC after a hefty windows update, As far as i know everything went well and shouldnt have been an issue but is the last thing that happened before the problem began.
The morning after i turned on my pc and made a coffie as usual and came back to see that the computer had made it to the dektop and completely frozen. The image on the screen was of the dektop. The mouse pointer was unresponsive, Alt-Ctrl-Delete and other commands failed to give any response. I attempted to disconnect and reconnect my mouse and keyboard. when i reconnected them there was no reponse and no power was sent to them (LED's on the wireless emmitor usually light up)
i pressed the main power button to turn off the pc. (similar to interupting using task manager and shutting your pc down from there) that was also non responsive. i then pressed the reset button, the pc restarted and worked fine for the rest of the day.
the next day the exact same thing happened. this time it froze twice and required two restarts untill it worked fine. on the second time the it worked fine for about 5 mins and then froze in a similar way. and then went into a bluescreen. i restarted and it worked fine. It remained on for at least 12 hours operating completely fine whilst i played two epic games of Sins of a Solar Empire XD.
Now we get to today.
The exact same thing happened as on the second day. First power on the computer freezes at the desktop, second it reaches the desktop and works fine for five minutes freezes and then bluescreens. This time on restart it goes into the bios menu and reads overclock failed, enter setup.
i chose to ignore this the first time and choose to continue startup assuming that the cpu would just default itself back to stock speeds of 2.4, only to get a bluescreen.
on the next startup all of the system fans ran, but the monitor did not display any image giving the response -no signal- when turned on. no harddrive noise occured suggesting that the computer didnt make it past the inital bios startup.
this happened several times each time i restart it doing the same thing.
i then disconnected the power checked all the cables and component connections and tried again.
the pc started up reading overclock failed. i manually reset all of the clocks to stock speed and started the pc as normal. This time i reached the desktop and the pc worked. I opened various hardware monitoring utilities to check voltages and temperatures. everything seemed to run as normal.
i went to get lunch, came back and it was working fine. i went to check my e-mails and search the interwebs only to be cut short about 5 mins into it by another bluescreen. upon restart it no longer mentions the overclocking failed message, but bluescreens after about 5 mins of activity.
and this is my current situation.
THe bluescreen reads something like: windows has shut down your computer to prevent hardware damage.
So from all this information i have narrowed it down to:
-Broken CPU from overclocking
-Broken PSU because its of a poor quality
-Broken RAM after failed tinkering (mabe crashing due to build up of data over 5 mins)
-Broken Motherboard because of my bad hardware installation.
-Broken Windows attempting to prevent hardware damage where none is evident.
-Computer is too cold in the morning and has bad connections untill warmed up.
If anyone can help me it would be a huge help: I have recently finished my studies and have little to no money at the moment so buying a new pc is out of the question.
thanks to anyone in advance.
Edit: i think the computer actually freezes midway through the blue screen.
it does the first 3 checks to 100% but when it gets to the fourth; dump to disk, it only reaches 70-75% and then stops.
when it reaches the blue screen in safe mode it completes the dumpt to disk task and then restarts but restarts unresponsively with no display or power given to usb controls or hard drive noise suggesting it insta crashes.
