Locked

PC turns on, no beep, no image

By Jambass ·
Hi,
Before anything I want to say that, yes, I searched for problem and I found people in a similar situation before posting this. And sorry for any language mistakes.

My problem is that my computer turns on but doesn't make any sound (it usually does)and shows no image. I already switched the battery, cleared CMOS, tried other RAM sticks on every slot, video card (basically the hardware in the pc i'm using to write this). Then you might say: "Ok then it's fried... buy another one." :) BUT it has a particularity... If I let it disconnected from electricity, say for 1/2 days, when I connect everything again the PC works like nothing ever happened. Then I put my Hiren's Boot CD to test it and IT PASSES IN EVERY TEST. The thing is that when I reboot, if not the first at the second time it fails again...

I'm frustrated! Please, any help?

EDIT: Sorry guys I forgot to mention one thing (Maybe a very important one). When it boots well this message appears: "Checksum error - Press F1 to continue" and pressing F1 everything runs smoothly. Is a corrupted BIOS the reason for the problem?

PROBLEM SOLVED

REASON: Motherboard overheating.
SOLUTION: I followed dpalsen suggestion and put a big fan next to the motherboard. Everything runs smoothly now!

Thanks for all replies!

A thought....

I would look on the motherboard, particularly for "Popped caps" aka Popped up Capacitor. Basically they are the round cylinder objects with an x on top, they should be straight across, if some or even one of them are bumped up that could be the cause of the issue...

Capacitor's can be tricky, because they have a wide variety of issues they can cause... With all different symptoms.

I just saw your Edit, with the checksum error. that can be caused by a number of things, RAM timings, HDD cable's ect... Also is there a BIOS update available for your motherboard? What is the model?

I'm with patb071

A quick test.

Remove the Power cord from the PSU to discharge the Capacitors in the Power Supply. Then press the Power button for 10 seconds to discharge the Capacitors on the Motherboard. See if it will start. If it does start you can replace the (PSU) Power Supply Unit as it is faulty.

I tried and it did not start. I couldn't make the pc run well since I posted though.

Thanks.
