Do u have v-card? Use memtest to see if the memory is ok.

Thanks for the info.I have just tried a memory test and it was OK.
The computer is a HP Compaq Pressario SR5340AN. It has a Chipset nVidia MCP61 Motherboard. Do you think maybe this could be the problem?

Try to reinstall video driver(un-install video driver then restart the system and install new driver)?

If you get ANY symptoms BEFORE Windows loads, they are NOT caused by any software problem - that's (a) hardware problem(s).

The video symptoms CAN be caused by ram (installed in the mboard, removable) error problems. If the ram passes a ram diagnostics suite of tests, e.g. memtest86 or memtest86+ (different author), that's probably not the cause.

Freezing can be caused by zillions of things - hardware or software.

"Do u have v-card?"

Computers have a video adapter, but it's NOT a video (adapter on a ) CARD unless it's on a physical card that plugs into a slot on the mboard, and the physical card is removable.
Onboard video - a video adapter built into the mboard that is not removable - is NOT a CARD.

He use nVidia 6150se integrated. "

His mboard / main chipset does have that, but it also has a PCI-E X16 slot, and he has not stated whether he's using the onboard video.


If the ram passes a proper ram diagnostics suite of tests......

If you are NOT using a video card installed in the PCI-E X 16 slot, there are only a few things that can cause your video problems

- your video adapter that's built into the main chipset is defective or damaged

- your mboard is otherwise defective or damaged

- there's nothing wrong with the onboard video or the mboard but your power supply is failing

If you ARE using a PCI-E X16 video card in the PCI-E X16 slot,

- try removing the video card (AFTER you have removed the AC power to the computer), connecting your monitor to the onboard video port, and using the computer

Your problem could be caused by

- a poor connection of the card in it's slot. Unplug the AC power to the computer, or otherwise switch off the AC power to the computer , remove the video card, wipe off it's contacts, install it again, make sure it's all the way down in it's slot and that it's bracket is screwed to the case, then restore AC power and try the computer.
NOTE that PCI-E X16 slots have a clip or sliding piece that locks down the inner end of the card that you must move out of the way bto remove or install the card,

- a defective or damaged video card. NEVER plug it in or unplug it when the PS has live AC power to it, Even when the computer is not running, your mboard always has power in some places, including some of the contacts in thwe PCI-E X16 slot, if the PS has live AC power going to it.

- a failing power supply.
It could be failing either because
- it's been damaged or is defective
- or - you installed a PCI-E X16 card that has a video chipset that draws more power than the capacity of the original power can handle and the PS was damaged because of that.
The power supply that came with your computer has a 300 watt (total combined output) capacity.
The HP parts list for your system does not state the part number for or who made the power supply. Some HP / Compaq computers have a BESTEC power supply - those have a reputation for being much more likey to malfunction or fail completely.

Your mboard was made by ECS (Elite Computer Systems) for HP / Compaq.

ECS has a reputation for using the cheapest possible components in their mboards, including the electrolytic capacitors, and sometimes those capacitors were not not properly made and they tend to fail prematurely .

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

What to look for, mboard symptoms, example pictures:
Home page that site
- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.

Pictures of blown capacitors, other components, power supplies, fried Athlon cpus, etc.:

Failing power supplies are common and can cause your symptoms.
Check your PS.
See response 4 in this:

If you can borrow a power supply from another working computer, try connecting that.

If it is failing, you can usually replace it with any decent quality standard sized standard ATX PS with the same capacity or greater.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo (in quality) PS.
See response 3 in this:

Note - I may have mentioned Cooler Master in that - I have recently found some models have only a 1 year warranty, some are known to have premature fan failures, some are known to develop failing electrolytic capacitors.

If you're using a PCI-EX16 video card installed in the PCI-E X16 slot....

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you see any evidence of failed or failing electrolytic capacitors, the same problem is likely to happen again, if you need to replace the mboard and manage to find a used one for a reasonable price
