HP Pavillion a6352f will not boot

[scratch99]

I've done everything with no success. If anyone can help, that would be great.

This machine has been acting up for a while. It would work and then for some reason it would not boot. The screen would stay blank, then it would work again. It had vista as the original operating system. I reformated the hard drive and installed windows xp. Again it worked for a while and then died again and has been dead since. Now only the keyboard lightflshes and the cd drive flash when it is powered on.

I've replaced the motherboard and power supply. I've tried a different disc drive. I've tried a single memory module (there are 4) in each different slot. I've tried to get into the bios. I've disconnected all devices from the mother board and tried to get in the bios after reconnecting each one. I've removed the battery and let it sit foe a day. Anyway I've tried everything and still have the same problem. The only thing I have not tried is to get a new memory module and try that in a memory slot, but what are the chances that all memory modules in that machine would fry at the same time.

Have you tried to install the Windows Vista again on your system.?? Check whether the same problem occurs when you install Windows Vista. Have you flashed your BIOS while installing the Windows XP on the machine?? This can occur when you flash the BIOS and unfortunately there is no solution other than sending it to the Service Center. Give the more details about your machine so that we can come to know about the exact problem.
