Specs: Windows 7
Hi I Have a very serious problem on my pc & i will be greatfull if anyone provide me working solution detecting my problem...
My PC has..
1. AMD Sempron Processor (Ready for w7) 2.71 GH
2. 1 GB Zion DDR2 RAM
3.500 GB SEGATE SATA
4 Year old pc, Now Dual Boot Window 7 and Windows 8
Since i have buy my desktop there was no mejor/minor problem regarding my hardware & any other except 2 year ago pc was not booting as power key was not working when i was pressing button but after 2 days it automaticaly solved,this problem was arised 4-6 times in my pc 2year ago in a gap of average 6months,everytime after minimum 1 or 2 days it automaticaly solved.

So, After that from 2014 my pc was working fine but in last 6months my pc's both version in 7 & 8 also graphics not working, i mean to say resolation is like XP , & streatched after everytime format it automaticaly hapens even i instal motherboard driver,
& also when i started my pc date & time automaticaly set to 2002
everytime, and after booting showing that :- "press F2 to load defult setup & continue"
and when i press this pc works in normal & run
These all was ok & has solution BUT NOW THE MAJOR PROBLEM & I WANT SOLUTION FOR THIS IS----
Now (in last 20days) when i start my pc with 7 it runs but after some time(2or 3 hour) it crushes with some deep yellow sreecn or sometimes other ,this is not bluescreen, this is like if i open my ram during machine on...is like that...
also if i start with windows 8 as i have dual boot, so it crushes as soon as it on welcome screen on w8.
& after that my pc did'nt on or power not work for 2/3 hour , BUT PROCESOR FAN work & dvd writer on for 10-20 sec. but power button does'nt reflected its light & after some time 12hour power work and machine run,but if i wait 2 or 3days or more pc starts more normaly & reliable but again after a time get crush. on same method
THANKS FOR READING LONG NOTE, I THINK THIS WILL HELP YOU TO UNDERSTAND MY PROBLEM, MY QUES IS...WHY AFTER CRUSH INSTANTLY NOT WORKING POWER BUT PROCESSOR FAN WORK FOR LILLTE TIME & AFTER SOME TIME (3DAYS) IT ON, & EVERYTIME SHOWING PRESS F2 TO LOAD DEFULT SETUP & CONTINUE & DATE & TIME SET 1 JAN. 2002 YEAR AFTER ON....IS IT A PROBLEM FOR BIOS BATTERY OR ELSE?
WHAT IS THE PROBLEM?
THAK YOU.FOR READ.

"date/time reset"s usually indicate time to replace the CMOS battery... It's usually a flat shiny disk and clips into socket on the motherboard. Usually about the size of US/Canadian quarter, or a UK 10p piece (same size an an olde "shilling").

Is this a homebuilt PC or a bought one? If the latter what make/model. If the former - what make/model is the motherboard?

That initial info will enable us here to be more specific with the cmos battery (location etc) and also other possible problems/solutions too.

Check the cooling fans - surprising how much dust that can accrue around the vents...

RAM - it "might" be giving you grief; but there are other things to try first...; before considering changing any;- although one can clean the edge contacts to good effect (see below).

A few utilities to run at some stage... will likely follow from pholks various here...

Meanwhile... Power down fully; remove power cord too - important to do that.

Locate RAM modules and carefully remove each. Clean their edge contacts with a soft pencil style eraser. Ensure no "bits of eraser left on the edges. re-insert each module and then remove and re-insert a second/third time. Then leave then in. Re-inserting a few times ensures that any oxide in the board sockets is also (hopefully) removed... The eraser routine cleans the oxide off the RAM modules.

Power up and see - apart from the date/time (CMOS battery problem) - if things improve? If you can secure a new battery first - prior to RAM cleaning - do so; better order of events.

Also whilst you have case open - carefully check the cooling fan on the CPU; ensure it does run...

Thank You for reply
here i am further updating my current status after doing as u mentioned
1.CMOS battery i have already replaced & now there is no issue with date & time
2.Cooling Fan- There was huge dust in there but i have also cleaned it. but problem not solved
3.RAM- i have cleaned it up...but problem is still
FURTHER I AM MENTIONING MY CURRENT SITUATION
Windows 8.1
amd sempron zion 1gb ram
500gb sata
after 3-4 days when i use my pc then its start normaly & works good but after 2days everytime the same problem happened...& there every time when i restart or power on my pc problem is still going on repeatedly
& again after 3-4 days its works fine...i am testing it since 25days..
this is my present status & problem means some yellow,green type screen.
& the screen is divided 3 to 4 crack horizontaly with yellow or anather colour as cthe colour changes sometimes
so, now what is the problem?
my processor is fixed with motherbord ,is it a problem of processor over heating? need paste for it?
as i tested 7-8sec run my pc withour cooling fan but in that time processor was heated like untouchable in just 7seconds...........
