W764b - Completely random freezes

Sadly enough updating the BIOS hasnt fixed the problem, in fact, it only made it worse..

Atm my computer only boots up half of the time, it first gave an error about expressgate, which I disabled in BIOS to solve it. It then finally started again and I resumed my usual things, hoping it was fixed. After 10 or 15 minutes my system crashed again, same way it did as described in my original post.

Ofc I had to hard reset my system again, it started and locked at the loading screen, I did another hard reset and ran system repair. Everything works again, but I'm still expecting it to crash sooner or later.

I'm afraid that all this hard resetting is damaging my system, startup used to be alot faster at first and fans seemed to make less noise aswell. If it's not BIOS, what else could be the problem?

I was just wondering if you ever solved this problem. I am having the same problem, random freezes just like yours with no indication of why. The only difference is I have experienced this with xp and 7. It actually got worse with updating the bios just like you.

Yes it's solved, turns out it was one of my ram sticks was broken. They replaced them under garantee and i haven't had a crash since. I Hope it is as simple for you, gl anyway :).

I have an Asus m4a79t deluxe motherboard and am a little concerned it might be the motherboard. I also think it might be the memory or power supply but don't have the means to switch components because I don't have extra ones laying around.

I've run memtest to verify if my memory is having problems but it seems to run fine. How did you come to realize the memory was broken? I just don't want to buy more memory if that's not the problem. I'm glad to hear your problem was solved and thanks for replying back.

i have EXACT same problem... maybe my RAM is bad too.. but do not want to risk of buying it. i did buy a RAM that was very very cheap.... >.>; 2G

Because I couldn't find a solution I just did my computer back to the shop and asked them to look at it. He was only a month old so whatever the problem was, it was most likely caused by something during assembly. They found out what the prob was, not sure how they did it tho, they didn't tell me.

It was a bad bios flash. Asus has the latest bios version as 2402 but it doesn't do anything for my motherboard. I flashed it with the prior one that was 2304, I believe, and it seems to have fixed my problem. This bios did have something that it fixed/added to my motherboard. My motherboard was m4a79t deluxe btw.
