Screen frozen on Kubuntu logo 'quivering'.

[Shabakthanai]

A friend's student daughter brought me her laptop. She was installing Kubuntu and upon restart, the screen is frozen on the pre-login Kubuntu screen. The image is quivering.

Her processor is an Intel dual-core Gen210133 which I am unfamiliar. Apparently Sandy Bridge, but not much else is discussed in my initial search.

I am about 6 hours into a Memory test which shows only 1 hour and 22 minutes of wall time. The computer has made the 3rd pass and shows no errors, and I am not sure of the implications, other than if it is a memory problem, it is new to me.

Any attempt to restart to install an operating system is rejected at this point.

Does this sound like a HDD problem or

The memory provided by the manufacturer is unusual to me, 6GB in a 4GB - 2 GB configuration. I always balance the slots and thought it recommended.

Memory : 6039M 41359 MB/s

- Slot 0 : 4096 MB PC3-10600 - Hynix Semiconductor HMT351S6BFR8C-H9
- Slot 1 : 2048 MB PC3-10600 - Samsung M471B5773DH0-CH9

IMC : Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz / BCLK : 405 MHz
Settings: RAM : 2702MHz (DDR3-5404) / CAS : 9-9-9-24 / Dual Channel

The computer rejected my attempt to enter the BIOS to change the boot order so I could install again from USB ISO.

Any Recommendations Strange, HuH? Even at my level of understanding, someone asks for help

'Balancing' the amount of memory is not necessary. Most systems will use the lowest common denominator on the memory. IE: 9-9-9-24 timings will work with all the memory in the system. Remember this is dual-channel memory, so the 'mismatch' isn't seen by the other channel. But timings have to be the same so the system will set the slowest that both banks will run at.

If you can't get into the BIOS I'd check the manufacturer's website for how to reset the BIOS to it's defaults.

I'd also guess you may be looking at disk problems. If it boots a LiveDisk then boot one that will run checks on the HDD. But get into the BIOS first.
