In Need Of Help plz. gateway w350a computer does not boot.

My problem is that the laptop will not boot or anything. There would be time where i would go press the power button and the dvd drive would make noise as if it checks for a cd and usually then the hard drive light comes on and the computer boots. But there were some times just the dvd drive noise happens but drive light doesnt come on nothing on the screen comes on but after a few seconds the cpu fan turns on. And thats what its at now so i decided to open it up and boy were the HS vents were clogged.so i cleaned the fan and heat sink vents with some compressed air. and all clean and tidy but its still not booting. My best guess is that after many failed boots and the overheating the cpu might have burned out? Ive tried reseating the ram, taking the power plug off and battery out and holding power button down for 30 secs then putting the battery back in and plug and still the same result.hopefully someone can help me solve this. Anyone with any thoughts, suggestions? Thanks in advance. btw cpu is an amd turion tl-58 the laptop on the bottom says model w350a i know its a t series just not sure which one. could be t 1616 but not sure at all.

 

What GPU does it have?

 

I believe its the radeon x1270.

 

I dont fully understand, does it boot ok sometimes or is it completely dead?

 

it used to not boot sometimes. but now it doesnt boot at all. no bios no post shows. just the cd drive sound and the cpu fan turns on like 5 seconds later and nothing on screen.

 

Have you tried removing/replacing the CMOS battery and then trying to reseat the ram modules.

It might just need to have the system flushed to give it a restart.

 

yea i just finished trying that. i replaced the thermal paste this time using arctic silver and still same results. here im including pics of the cpu before i reapplied the paste. should i be worried about the black ring around the cpu? i also included a small video clip of what it does when i press the power button. is there other things i should look at maybe the gpu. then again im not sure where it is located any suggestions?





in this clip you can see the all the lights blink then the dvd drive light and usually the hard drive light would blink and it would boot but as you can see that doesnt happen now. but the cpu fan does come on and hard drive does spin.

 

I dont think it's the CPU.

Do you hear any beeps?

Does an external monitor work?

 

Thanks for everyone trying to help me.

No beeps, external monitor does not work. Could the hard drive be a cause at all?

 

take it out.

You should still be able to get into BIOS without a HDD

 

yea i figured if the hdd was bad it would still boot and give me something like disk not found. what else could my problem be?

 

Im going to replace the drive see if that does anything. would overheating burn the gpu? and then cause the laptop not to boot?

 

nope new hard drive didnt do the trick. how can i know that its definitely the video processor

 

It's hard to guess what it could be.

When you plug in the power cord, do the lights work properly?

 

I'm having the exactly same issue. Did anybody every found out what the problem is?

 

Have u tried to boot the laptop without the battery on it just off ac?
