PC stuck at BIOS

My computer is really old (7 years) and I plan on building my own new computer soon for the first time. But, for now I still need this one and it isn't working (I'm posting this from my dad's laptop). Around the beginning of the summer I first had a problem where my computer would not boot. Everything inside the computer sounds like it is running fine but the normal BIOS screen has small white lines over it. It gets stuck like this and does not boot properly until I restart it several times. The screen looks like thishttp://mail.aol.com/36912-111/aol-6/en-us/mail/get-attachment.aspx?uid=27744200&folder=OldMail&partId=1
This happened whenever I turned off my computer and turned it back on, but always fixed after a few more restarts. This morning though I restarted it at least 30 times and it wont work. I've searched around for a lot of solutions and none of them have worked so far. I've reseated my ram sticks, CMOS battery, and video card. None of this worked. I tried using my old monitor and I got the same screen. I also tried starting it up with no USB devices plugged in so I do not think that it is my power supply either. I cannot access the Boot Menu or BIOS Settings. I can't do anything at all to change the screen. I have no idea what to do now.... :cry Thanks for your help in advance

 

I removed it from the optical drive and that did not work. Perhaps I need a completely new CMOS battery?

 

A new CMOS battery is definitely worth a try. A bad battery can cause weird boot problems.

In the meantime try unplugging the computer, remove the CMOS battery, plug back in and try to boot without the battery. If no go then unplug, put the battery back, plug in and try to boot. (Sometimes this scenario works for some reason.)

If still no boot replace the battery. Some machines require a good battery to boot properly.

 

Well that didn't work either =\. I am gonna go buy a new battery today. Either way I think it's time I got serious about building my new computer...:cool

 

It's not the battery because I put a new one in and it still doesn't work.

 

Does the motherboard have onboard video in addition to your video card? If it does you could try connecting to that instead of the video card.

Other than that the last thing to try is go back to plodr's suggestion but disconnect the power cables from both the HD and optical drive. So you have as little attached as possible. Just RAM, keyboard, video card and monitor. ( This would only be a test to see if you can get to the normal BIOS screen without it being scrambled, you obviously wouldn't have any devices to boot to attached.)

 

Neither of those worked either =\. Someone else suggested that maybe my motherboard is messed up. That would mean there's no hope right? Because there's no way I'm buying a new motherboard for this computer I wouldn't be using for much longer...

 

It could be the motherboard but you are getting something on screen. Usually a bad motherboard is just bad, you get nothing.

Unplugging AC and removing the battery for a minute should reset CMOS. So if your CMOS had been corrupted then it should have been reloaded to defaults already. But the scrambled text sure sounds like a CMOS problem to me.
The new battery should have done something to alleviate the problem. I think you should go ahead and reconnect the HD and/or optical drive and take a break and leave it unplugged with the battery out for several hours/overnight. Put the battery in and connect AC and try starting it multiple times (like you have in the past) to see if you still can get it to boot even once.

 

I think that it did get reset because when I started it, it sounded like it started up twice really fast in a row. But this happened last time I took out the CMOS battery for a while and nothing has happened. Even after restarting it several more times.
