PC wouldn't boot - beeps - can any forum members please help?
Hello
I have an PcPwhich will not boot and just emits a series of beeps. I contacted HP support, but they are not helping because it is out of warranty. The members of the forum you will suggest how to proceed...
Thanks in advance

product_name: HP Pavilion Media Center TV m7475.uk, a desktop PC Bundle
PART_NUMBER: EV989AA
operating system: Microsoft Windows XP Media Center Edition
description of the problem: when I turn on the computer it does not start and emits continuous about 3 second beeps separated by approximately 2 second gaps.
The motherboard has AWARD BIOS.
I looked at the beep codes for the BIOS on the HP site that says
Continuous beep without pause = serious related problem of the system such as overheating of the CPU.
It is not clear if this meens a continuous beep or an endless series of beeps.
I looked inside of the case and the fins under the processor fan are very clogged with dust and lint, upward which means that the airflow to the CPU has been very poor.
What are these beeps indicating?
What is the overheating of the CPU?
The CPU is likely to be damaged?
The motherboard has a certain type of cutting to protect the CPU overheating?
If I remove the cooler, clean mud, clean the old thermal paste and replace the cooler new thermal paste, what might solve the problem?
Is there anything else that could cause this and how to solve it?

Hi thanks for the reply.
It looks like the web page I've seen.
I cleaned the fins of the cooler and reassembled the heatsink on the processor with the new thermal paste, but the machine is still there as before beep.
I tested the power supply with a Maplin PSU tester.
All voltages are within the tolerance but the Power Good signal appears in the form 00ms and the tester flags this up as a fault.
The leaflet said that the PG should be between 100-900ms.
Could be the cause of the problem?
Unfortunately I do ' t have a spare PSU to test the computer with.
I'm not sure what good the signal power is supposed to do. I tried a web search, but I found no good explanations.
See you soon
Tony
Sorry to be the bearer of bad news, but your Maplin power supply Tester is pretty much worthless. It only said the advertising.
Unplug the power connector on the PSU. Remove and then reinstall the memory modules. Give each module in the same slot DIMM you removed since. Connect the power connector to the power supply and press the power button to see if it will boot into Windows.
Please post your results.
Kind regards

I have Windows 8 is installed and an iso of Windows 8.1 on my USB.
My previous version of windows (which is already installed on the hard drive) will erase if I boot from a bootable USB. Please help me!
When you upgrade to 8.1 Windows it will replace your Windows 8.0. The only way I know to have both is to buy a copy of Windows 8.1 and install on another partition or drive. Hope this helps and if you need another post to help and we will be happy to help you.

Y580 NEW plant all the time? Can't do anything PLEASE HELP...
I recently bought a Y580 for almost $1000 (something like 2 or 3 weeks). First of all, it worked perfectly, but yesterday I had to reboot using the button, because it crashed. Now, whenever I start it, either I get a black screen or it freezes when I open something like firefox, explore or just a folder. AND the worst thing is that Ctrl + Alt + Delete does not work so I can't open the Task Manager.
I don't know if this can help, but once when I reboot the computer, I noticed a message saying something about Verifyhost.exe. And I don't know if it's a coincidence, but "Lenovo TouchZone" reappeared with these questions (I had deleted when I got my computer).
I'm begging you help me please I am a student and I bought this computer because I needed a good for the College. first of all, I was happy about it but now I'm really angry and I don't know what to do. I can't contact the support cause I don't have a phone that's why I am posting this here. Please help me.
Thank you
I did a system restore and now everything works. Hope this helps those who have the same problem. I hope that this will never happen again - very bad experience.
