Really Unstable

Now my PC is crashing/restarting loads and i'm really frustrated now.

Ive tried everything i can think off :confused:

But i will have to explain as im desperate for help so i know what to do.

1: Bought a new 1gb ram stick and installed it correctly, The result was it made no difference to my PC.

2: I have taken my graphics card out and i'm currently using onboard graphics, This also has made no difference.

3: Changed over my PSU to a PSU i know is fine, No change.

4:Checked all cables fans etc. This had no effect either.

5: Performed an intensive drive cleaner then reinstalled, Still no change.

6: I checked my HDD for any errors and also checked S.M.A.R.T and that reports that my HDD is in a good working order.

7: Scaned for any Virus/Malware and it came up clean.

I scanned for errors using PC Doctor and my onboard graphics video memory test failed. I did a further scan using Windows memory diagnostics and that failed the test.

Is it possible that a broken ram slot or just a dying MOBO could report ram as bad even if its new? Or actually make it break? Basically it restarts almost constantly plus programs,Internet crashes loads.

What the hell is wrong with it? And does it look like i should purchase a new MOBO and a new CPU? I really am desperate for an answer.

It would help of you told us what components you are talking about?

Did you build this PC yourself or?

Did you try memtest to?.....

Or try just the new stick of ram on its own?...

Could be that the ram you have in there (not the new stuff) is faulty....

Windows Memory Diagnostic has been known to pick up errors that memtest misses, though how accurate it is i do not know.

A friend uses it at work (works in IT fixing PC's etc) and he says it's a very good test, can't say i've ever had to use one though, i've usually got spare ram lying around to bung in a system, much quicker for testing.

The ram may not be compatible with the mobo, or it might need the timings and voltage to be set manually in the BIOS.

This pc is a HP A1128.UK

I took the old ram out and replaced with the new ram stick, As memtest said my old stick was broke.

AMD64 3000+
SOCKET 939 MOBO ddr 400
XP HOME
1GB 400MHZ PC3200 SUPERTALENT [new ram]
400 Akasa PSU [took that out and replaced with the original one]
X800 GTO2 [took that out]

So i'm back to using the computer as i first got it. Also i was having these problems before i replaced the ram, And thought it would fix it.
