Help!!!!! pc hangs on bios screen during startup

Motherboard ??

Try swapping the ram sticks around or removing one or the other sticks, try cleaning the processors contacts with a pencil eraser (had an issue with one LGA755 where this really helped), try the eraser on the edge connector of the ram sticks (it can remove surface dirt without abrasing the contacts and has worked for me on quite a few machines).

What do.u mean by motherboard??

I tried swaping the ram sticks but still the problem persists.
Can I use a pencil eraser directly on the gold coloured contacts on the processor ? Will it not damage the processor?
I used pencil eraser on the ram sticks but nothing happened. Please reply

How can you be sure that the motherboard isn't fault??  

I am not sure about any of the components & I don't have a spare motherboard to cross check each & every component.
So please tell me how can I find out which component is faulty?

The problem occurred when at midday I started my PC watched a movie and then I just turned of the monitor and went to have my lunch, when I returned back I turned my monitor on but nothing displayed on the screen and my monitor went into power saving mode bit the CPU was still on and the hard disk led was still glowing I restarted my PC but everytime I use to to get stuck on the BIOS screen or os startup screen.it worked fine the previous day I played games watched movies

might be over heat issues , according to my knowledge if your cpu is too hot you don't get o go past bios screen and sometimes not even bios screen .


try reset cmos ( if you don't know , easiest and fastes t way is removing battery in mother board wait for 5 mins and put it back )


and make sure cpu fan is running ..


idk these are the problems I faced when my pc ran into similar disaster.

I've used the eraser on a LGA755 core2 quad which refused to post, it posted with an alternert processor so I decided to clean the contacts on the original processor with an eraser and it started working.

I had this and it was faulty ram.

Hope This Helps

Here are the possible issues with your PC :
1. Check out if your PC is over heating ?
2. Check out if the CPU Fan is working properly ? Try cleaning the fan with a brush !
3. Re-apply the thermal paste on your processor.
4. Try putting the RAMs in different combinations.
5. if it doesn't help, get your BIOS upgraded !

BEST OF LUCK !!
