Aspire 4540 flickering...help...
Bob2004:
Look up the manual for your laptop, and see what it says about error codes. Most computers will beep in different sequences at startup if there's an error (eg. 3 short beeps for memory error, 2 long beeps for overclocking error, etc) (some will have lights instead - I had an old DELL PC which had 4 lights on the front which lit up in different combinations to indicate errors), and the manual will explain what each code means. That should give you an idea of where the problem lies.
EDIT: That said, I just looked up the service manual, and it makes no mention of any error codes, so maybe your laptop doesn't have this feature. If you got a manual or anything with the laptop, check that too.

is a bad videocard bios possible? it'll ultimately solve even the flickering problem if it is the case.
Edit: i mean't bad bios version, like a buggy version, this could also apply to the motherboard's bios which would also solve why win7 was getting rejected, or thats what i remember him saying a couple of days ago.

No idea if it'll fix the problem, but the service manual I linked definitely had instructions for restoring faulty BIOS (though you probably need a recovery CD to do it), and it had diagrams showing where the various jumpers for clearing settings and things are. Since the graphics card is integrated into the motherboad, I'd assume they share the same BIOS, but who knows.
Personally, I think it's unlikely to be the problem, but it's worth a try. I'm more inclined to think the cause is related to the beeping problems that occur when reinstalling Windows - modern computers normally only beep to indicate an error, so it might well be a code of some kind.

Most laptops (by most meaning all the laptops I worked with) doesn't have a feature to overclock them. I wouldn't overclock them anyways. Do you have an external mouse connected to the laptop?
