I m currently in Pune . I have a desktop back home ,configuration of which is given in my signature , The setup is overall 4 years old . Graphics card ,sound card & SMPS are 2 years old .
Now major connections are
Power connection -> UPS(which gives no backup) ->SMPS
PC->Sound card ->5.1 speaker
PC->Graphics card->DVI port ->LCD monitor
The CPU is run in 30% overclock using Bios settings itself ,ie the Bios provide 30% performance increase option . However no liquid cooling ,only 3 fans installed along with CPU,GPU & SMPS fan .
Installed Operating system - WIN 7 Ultimate , SP1 + Latest updates (up to last week)
Internet - Through wifi ->Wifi card installed in MB
Problems - >
1. The PC FREEZES at any random point . Normally it freezes at welcome screen /
"configuring new updates " /after loading windows ,running it for say 10 minutes.
To check whether windows is causing any trouble , i decided to restore windows through acronis rescue disk in DOS environment ,after selecting DVD-Rom as first boot device , using a backup stored in PC itself ( in a logical drive ,not c: ). After restore session begin PC freezes at 30% . So i m guessing it is definitely a hardware problem ,as the acronis environment is normally driver free ,& if i m not wrong the hard disk has gone to dark side.
2. Once this problem occurs ,the monitor suddenly losses signal . What i mean is the monitor display " Digital , Power saving mode " . Normally it shows so when computer is in sleep . Also the LED in monitor changes to orange which shows that monitor is thinking that PC is in sleep mode. However even after tapping multiples time in keyboard ,there is no change in computer ie black screen & no signal .
Also if at this stage i press "Reset" or "Power" button in CPU ,there is NO RESPONSE . What i mean is nor does the PC reset nor shutdown . If i do a cold shutdown ,by pressing the power button for a long time then the PC shut down but refuses to turn on next time (ie there is no response even if i press the power key" . The only way is to manually flip the power switch in switch box where UPS is connected off-on . I don't know how but it sort of reset the PC & it turn on next time when i press the Power key.
Now these freezing problem is comparatively new ,but the monitor losing signal is quite old ,about 2 years old . Previously i used to think that maybe ,Monitor or the cable connecting monitor to GPU is in fault . But they seem to work very well when i use them with some other CPU (Friends) .Only in My cpu this problem occurs. I have not tested my GPU in others PC ,as i don't have faith on my friends who seems to overclock every thing that they can lay hands on .
3. A seemingly new problem has also start occurring . Whenever this freezing problem occurs in windows ,& speakers are on ,suddenly a screeching noise of atom bomb level becomes to come from speakers ,all 5 of them . This does not occur if i use the inbuilt sound chip of motherboard or if i degrade the sound quality from 96000 KHz to 44000 KHz . But I don't think that sound card or speakers are culprit as they don't have their own brain unlike graphics card . This problem get solved for few days if i reinstall the drivers ,but whenever the freeze occurs that sound occurs . If the speakers are connected to internal sound card ,then if at that time freeze occurs the atomic scale sound does not come.
To check whether might be GPU is culprit ,one day after the monitor lost signal ,i opened up the cabinet . Both CPU & GPU were working ,with their respective Fans rotating . So i just could not understand what is happening .
Also once in a while my sister said she smelled a burning smell near my PC ,though when she investigated or when i investigated later ,no smell was present . Incidentally the freeze problem began to occur a few months after this burning smell . Though the "Lost signal " was from a great while ago .
Once some body told me that this problem is due to inadequate power supply . Previously i was using the inbuilt cabinet SMPS of 420 or 450 . Now i have a Zebronics platinum series SMPS that is 500W (bought 2 years ago) & instead of a small exhaust fan in normally smps ,it has a big one facing downwards . However even after installing the Performance SMPS ,i m having the problem . The truth in these 2 years i have not even played High - Performance games in a while ,in fact the only thing why the pc is being used ,is to test java programs as my sister is pursuing her BE-Computer & to see movies once in a while . Does these 2 jobs have so much power consumption capacity , this i m unable to digest .
Also so far as i know from last 1 year the PC is not even running in overclock condition as whenever this freeze problems occur it seems bios reset it self to factory settings.
Please suggest What might be the Problem ? Or should i say What might be the problems ?
