Problems With My Pc...

[Sepu]

hi

It's since months that I've problems with my PC.
Sometimes, when I start it, it says in the BIOS "The CPU frequency it's wrong, the computer is in safe mode.."
I can choose the CPU frequency btw:
-Manual
-1800
-2400

The CPU is a 1.8 Ghz, so I choose 1800, but the problem continues again and again.
Now, since yesterday, I tried to switch on the PC, but it doesn't do the Beep of the BIOS anymore
I can't understand if I've to change the MOBO or maybe the power supply, because I put off every other hardware and the BIOS doesn't start anyway.

Any idea? thanks
Chris

I once had a problem that sounds a bit like yours !!!
Are you at least able to go into your Bios ???
If yes, go into your bios and try putting everything at DEFAULT !!!
That solved my problem !!! hope it helps

Hi there, thanks for the reply.
I took the PC back to the shop....I couldn't access the BIOS.
I tried to reset it by myself, but I don't know where I failed.
Anyway, they reset the BIOS, but there was a problem with the main HD.

Finally, I lost my main HD with 40Gb of shit on it

Now I bought a new HD, today I had a lot of problems on reinstalling the hardware (it continues to reboot, dunno why).

At the end, I'm back online

PS: Still have problems.

It starts correctly, and then it says a black window with "No signal detected" and continue to reboot.
The black window come in a different time each time, during the load of Windows, or when I'm just entered and I can see my Desktop

I will try post in some other forums, I don't think someone here can help me

later

Sudden reboots..I took care of a similar problem a while ago.
The way u discripe how things are unfolding..let me see.

sudden reboots and difficulties with the processor, HardDisc damaged etc. I'm not saying I know 100% what's the problem, but I could be a case of leaking capacitators. I wouldn't harm to at least exclude it though.

I would advise u to open up ur case and check-out the capacitators on the board. Look carefully at them and see if there are any of them with black/brownish stuff on top of 'em or at the base (where they are connected to the motherboard)coming out. Also try to determine wether there are any bulged capacitators present on the board.

Here's an article has some picturs of what a leaking capacitator looks like. Don't all the technical talk in the article, just look at the pic's

Leaking capacitator can cause un-stable behaviour of your system, damage parts such as hard-disk's, CPU, soundcards and videocarts and ultimately lead to a destroyed motherboard (if you look at the pictures you can figure out why)

A different cause may be faulty RAM, this also happen occasionally and also causes unpredictable behavious of ur PC

[Sepu]

right now they only thing that happens is that I switch it on, I leave it reboot itself for around 10 times, and every time it loads some seconds more.
At the end, I can login into windows, and it works...

It's really weird because after all these reboots, it works

Thanks for the reply and the inputs;)

sounds like your processor could be overheating which can cause your PC to reboot. Make sure the fan on your processor is working correctly.

[Sepu]

the temperature is good for what I can see in the BIOS....

[sorrowman]

I wouldn't say that the temperature reading right after booting or not booting at all (since u r going to the BIOS) is giving a good indication of how the systems temps look. Plus, I also don't think the CPU is overheating. When CPU is overheating it will just slowdown, or completely shut-down the PC (depending on the hardware security measures supported by ur mother board, but sudden-reboots don't happen when CPU is overheating.

To tell something about the temps you have to let it run for a few hours idle (do nothing with it) and the have it running a bit when stressed (rendering a video is serious CPU intensive works, so if both go down well the CPU is probably OK.

What type of CPU du u have, AMD Athlon XP, Sempron, Athlon 64, or Intel P4, Celeron or something

It also may be worth checking out al the electric connectors, and wires in the case, is the HD connected OK to the mother board, same for DVD-rom/DVD-RW/Floopy drives etc. Somewhat loose wires can also lead to unstable/unpredictable behaviour.

Since the behaviour seems to be evolving all the time I wouldn't be surprised if u end up with a wrecked PC in the end, so make some backups while u still can before things go down the drain.

[Sepu]

I will check all my connections, and try to remove the 2 DVD-ROM to see if it works...if not maybe I've to format the HD.

The CPU is a Intel Pentium IV 1.8Ghz, the temperature is good.
I remember I had a problem with the fan, and then when the temperature was too much high on the start, I couldn't start the PC anymore..

So, this isn't the problem right now.
