View Full Version : HP a6340a gone funky, help with trouble shoot please

Hi there guys,

My flatmate's old HP a6340a desktop computer, acting funky:

Core 2 Dual processor (don't know what exactly)
2 GB of RAM (2 x 1GB)
Radeon HD5450 graphics card
500GB Seagate HDD
Windows Vista

what it is actually doing once it gets turned on:

CPU fan goes, case fan goes, DVD drive light blinks for a few times
No display
About 3 seconds later, everything gets shut off
Wait another 3 seconds, turns itself back on again
The process repeats, until you long press the power button to shut it down.
No beeps can be heard during the process.

What I have done so far:

Brand new power supply (guaranteed to work properly), didn't help.
Booting without DVD drive, didn't help.
Booting with just 1 RAM stick at a time, didn't help.

out of frustration, I pulled both RAM sticks out (booted without RAMs), exactly
the same symptom...:badpc:

Any ideas? it seems to me that both RAM sticks are gone..or perhaps it is something
worst?? any recommendations will be greatly appreciated :D

You've done a good job of eliminating issues.

What remains is moslt likely the graphics card, or the motherboard as the problems.

But before doing anything more, make sure that ALL unneccessary USB devices are disconnected - all thumb drives, all external drives, and give it another try.

Then try without the graphics card. With luck the mobo will have a built in alternative graphics system, which you might have to activate via the BIOS.

Thanks Paul.

There is no USB device connected other than a USB keyboard.

Will remove the graphics card and try again, will keep you posted.. :D
